Definitions
- This invention relates to new and useful asphalt emulsions used for spray applied road construction or repair applications and to non-paving applications such as roof and asphaltic coatings.
- Tack coat is a spray emulsion applied to the existing surface to improve adhesion with the new paving.
- Cold mix is emulsion mixed with aggregate for pothole patching or moderately thick paving up to two inches thick.
- Fog seal is a cosmetic spray applied to the finished pavement.
- Chip seal is a spray emulsion that is then covered with a thin layer of stones.
- Slurry seal and microsurfacing are mixtures of emulsion and a complex mixed aggregate which is applied on top of old pavement .
- emulsions can be cationic, anionic or non-ionic depending upon the emulsifier.
- a critical emulsion characteristic is the amount of time from when the emulsion is mixed with or contacts the aggregate until the asphalt and water in the emulsion separate which causes the asphalt to set giving a firm water resistant coating which holds the aggregate together and adheres it to the old pavement.
- the set times are normally categorized as quick set, rapid set, medium set and slow set. ASTM standards have been promulgated for standardized emulsions within these set time categories which are commonly used for contracting specifications (See ASTM D 2397) .
- Microsurfacing and slurry seal systems use a cationic or anionic asphalt emulsion in water, which is mixed at the work site with an aggregate containing a high quantity of fines or dusty material. For such applications at least 25%, and sometimes as much as 90% of the aggregate will pass through a 16 mesh screen (USS) .
- USS 16 mesh screen
- the emulsion breaks and the asphalt/aggregate separates from the water phase. Before the emulsion breaks or sets, the mixture is applied to the road surface and leveled.
- Microsurfacing systems tend to be polymer modified and can be applied in relatively thick layers, as they are commonly used for rut filling. Slurry seal systems are typically applied in layers only as thick as the largest stone in the composition.
- Amidoamine and imidazoline and their associated quaternary e ulsifiers have been described as cationic emulsifiers for such microsurfacing and/or slurry seal applications as have polyamines such as alkyl aminopolypropylamines and other more complex surfactants.
- polyamines such as alkyl aminopolypropylamines and other more complex surfactants.
- breaking of a cationic emulsion is usually triggered by the contact with stone or other aggregate material, much work has been done investigating cationic emulsifiers which provide longer breaking times so that the mixture does not set up in the mixing equipment before the slurry can be applied to the road surface.
- chip seal Another road maintenance method is known as a "chip seal".
- a chip seal application an asphalt emulsion is sprayed on to the road surface and then clean, frequently washed, narrow size range, stone aggregate, typically about 1/4 inch (6.4 mm) and containing little fines material passing thru 200 mesh, is spread on top of the sprayed emulsion.
- Aggregate sizes used for various types of chip seal contain essentially no material passing 16 mesh, and may go as high as 3/4 inch mesh, or even higher, with each application typically using a narrow fractional size range within these parameters.
- the chip seal application is only one stone thick, but in the chip seal technique the aggregate is not mixed with the asphalt emulsion before being applied to the road.
- the repair is typically finished with light tire roller compaction.
- VIM-65 chip seal emulsion formulations
- ASTM D 2397 CRS-2 emulsion a rapid setting emulsion, such as an ASTM D 2397 CRS-2 emulsion, is mixed with stones at a rate of 30 g emulsion and 200 grams of prewetted and towel dried stones for a maximum of 30 seconds, followed by an immediate washing with sprinkled water (using quart can with 18 holes of 0.125 inch dia) , until clear water is obtained or 3/4 of can has been emptied.
- 100% coverage of the stones with a tacky asphalt coating must be observed.
- Conventional cationic rapid setting asphalt emulsion formulations typically provide only 60-75% coating under this test.
- chip seal and slurry- seal /microsurfacing are not mixed with the aggregate prior to application to the road surface
- this VIM-65 test includes mixing simply to insure reproducible exposure of the stone surfaces to the emulsion and to defined a fixed period of time for the emulsion to set.
- a proprietary formulation capable of passing this test has reportedly been developed by some suppliers, but that formulation is said to be highly unstable, with a safe storage time of only a few days or less.
- the practice of adding a destabilizing agent to an asphalt emulsion is known but is extremely risky and unacceptable.
- One of the critical specifications for emulsions is the 'sieve test' which measures the amount of deemulisified asphalt that is captured on a #20 USS mesh screen after the emulsion has been stored, typically for a 7 day period. If more than 0.1% is captured in the screen the emulsion fails the test and should not be used for spray applications because it can plug or partially plug the spray nozzles which will cause uneven emulsion application to the road surface and subsequent failure.
- the emulsions are frequently stored in tanks of 50,000 gallons (189,000 L) or more. If the emulsion breaks in such a large tank, the resulting mixture of water and asphalt is very difficult to separate and reprocess. The asphalt is frequently not pumpable until heated above the boiling point of water thus potentially creating steam in a dangerous situation. Even though there are some similarities between chip seal and slurry seal applications, there are very few emulsifiers developed for one application which are used extensively in the other application. The fundamental reason is that the aggregate used in slurry seal contains a large amount of material passing through #16 Mesh which, due to its high specific surface area, reacts very strongly with the emulsifying surfactant.
- the aggregate used in chip seal is much larger, has a smaller specific surface area, and thus reacts to a lesser extent. This is compensated for to some extent by the fact that the surfactant use levels are much higher for slurry seal than for chip seal. But even so, if emulsions made with most chip seal emulsifiers were used in slurry seal/microsurfacing they would most likely break prematurely causing the slurry seal mixture to become hard and unflowable in the mixing equipment, or to become too stiff to spread in an even thin layer on the old pavement and adhere well to the old pavement.
- amidoamines or imidazoline emulsifiers prepared from fatty acids or their esters, and ethylenepolyamines can be employed effectively as emulsifiers for sprayed emulsion applications, and further that, within narrow use ranges, such emulsifiers may be used to prepare stable asphalt emulsions useful for the most demanding chip seal applications.
- coating percentages in excess of 90% can be readily obtained under the rigorous VIM-65 test, described above, and preferred compositions can be formulated which fully meet the 100% coating requirement under this test.
- the emulsions prepared in this manner have little tendency to break in the storage tank under conventional storage conditions for cationic rapid set emulsions. Under the conditions of the sieve test, described above, not more than 0.1% of the emulsion will be retained on a 20 mesh USS screen after a storage period of 7 days.
- the invention is a surface repair or finishing method comprising: (a) applying an aqueous asphalt residue emulsion onto a substrate surface; (b) applying stone aggregate to the emulsion after the emulsion has been applied to the surface, wherein the stone aggregate comprises no more than 10% by weight of material of less than 16 mesh USS size, and the emulsion comprises a fatty acid/ethylenepolyamine emulsifier characterized by at least one fatty acid residue and an ethylenepolyamine residue, the fatty acid residue (s) and the ethylenepolyamine residue together forming an amidoamine compound or an imidazoline compound or a mixture thereof.
- the method is particularly useful for chip seal road repair applications. However, it may also be advantageously employed in flat roof installation and repair applications, where ambient temperature application allows for reduced production volatiles and less hazard to workers compared to conventional hot tar roofing techniques .
- a further aspect of the invention is a surface repair or finishing method comprising spray applying an aqueous asphalt residue emulsion onto a substrate surface, wherein the emulsion comprises an asphalt residue content of at least 60%, and a fatty acid/ethylenepolyamine emulsifier characterized by at least one fatty acid residue and an ethylenepolyamine residue, the fatty acid residue (s) and the ethylenepolyamine residue together forming an amidoamine compound or an imidazoline compound or a mixture thereof.
- spray application of such emulsions can be used to provide asphalt coatings on concrete substrates such as concrete pipe and on other substrates such as automobile underbodies . For these latter applications, too, spray application of a rapid setting storage stable emulsion provides reduced environmental and safety hazards compared to spraying hot tar.
- a further application is an aqueous asphalt emulsion composition.
- the emulsion comprises, on a composition weight basis: 65-80%, preferably 68-75%, by weight of the emulsion of asphalt residue; and
- a fatty acid/ethylenepolyamine emulsifier characterized by at least one fatty acid residue and an ethylenepolyamine residue, the fatty acid residue (s) and the ethylenepolyamine residue together forming an amidoamine compound or an imidazoline compound or a mixture thereof.
- the emulsion is suitably prepared using a conventional asphalt residue material for the specific application contemplated for the emulsion.
- a conventional asphalt residue material for chip seal road repair, AC5-AC20 asphalts, blends thereof, and equivalents of such asphalts are preferred, more preferably AC10 asphalt or equivalent.
- the emulsion contain at least 65% by weight of the asphalt residue content, more preferably at least 68% by weight.
- the maximum asphalt residue load which may be practically formulated for spray applications will be about 80% by weight or less, more typically about 75%. For some pour and spread application techniques somewhat higher asphalt residue loading may be practical.
- amidoamine or imidazoline emulsifiers of the invention are suitably prepared from fatty acids or their esters, and ethylenepolyamines .
- ethylenepolyamines includes ethyleneadiamine and ethylenediamine oligomers of the formula:
- Suitable ethylenepolyamines include, in addition to ethylenediamine, diethylenetriamine (DETA) , triethylenetetraamine (TETA) and tetraethylenepentaamine (TEPA) , etc.
- DETA diethylenetriamine
- TETA triethylenetetraamine
- TEPA tetraethylenepentaamine
- emulsifiers are fatty acid amidoamines and imidazolines based on diethylenetriamine (FA-DETA) .
- fatty acid may be reacted in known manner with diethylenetriamine to produce an amidoamine or imidazoline.
- fatty acid esters especially methyl esters and triglycerides, can be used to make amidoamines and imidazolines in place of fatty acids and thus the method of making the emulsifier should not be considered limited to direct acid/amine reaction products .
- the fatty acid residue is suitably derived from a saturated or unsaturated C 12 -C 22 fatty acid or a mixture of fatty acids, at least 75% of which are C 12 -C 22 fatty acids.
- the fatty acid moiety is a saturated or unsaturated mixture at least 75% of which is C 14 -C 22 , more preferably Ci 4 -i 6 - Preferred fatty acid moieties are obtained from tall oil fatty acid (TOFA) , tallow fatty acid, porcine fatty acid, palm oil fatty acid, cannola oil fatty acid or rapeseed oil fatty acid, or the triglycerides or methyl esters thereof.
- TOFA tall oil fatty acid
- tallow fatty acid porcine fatty acid
- palm oil fatty acid cannola oil fatty acid or rapeseed oil fatty acid
- the triglycerides or methyl esters thereof or the triglycerides or methyl esters thereof.
- the presence of minor amounts of imidazoline does not materially change the performance of the emulsifier, in fact reaction products which are predominantly imidazoline are useful as emulsifiers in the invention.
- the level of emulsifier used should only be as high as necessary to give a storage stable emulsion and the asphalt residue content should be as high as possible, as indicated by passing the sieve test. It is also believed that very small asphalt droplets should be minimized as they may stabilize the emulsion excessively.
- the amidoamine and/or imidazoline emulsifiers of this invention allow an effective emulsion to be easily made.
- the emulsifier may suitably be included in the emulsion in an amount of about 0.75% by weight or less, preferably about 0.5% or less.
- the emulsion contain about 65-80% asphalt residue and 0.1- 0.5% of the emulsifier.
- the emulsifier may be prepared at a mole ratio of fatty acid to ethylenepolyamine of 1:1 to 1:1.5, or even higher, and may include both monoacid and diacid adducts .
- the Saybolt-Furol viscosity is suitably 100 sec. or greater, preferably 200-300 sec.
- Preferred formulations contain about 68-75% asphalt residue and 0.15-0.35% of the emulsifier and have a pH of between 2.5 and 3.0.
- the emulsifier is suitably dissolved or dispersed in water by neutralizing with a mineral acid, suitably at a temperature of about 140° to 150°F (60-66°C), to form an emulsifier solution or mixture such that at least most of the emulsifier is dissolved in water.
- Hydrochloric acid is the preferred mineral acid.
- the mineral acid is added in an amount to provide an acidic emulsifier solution, preferably with a pH range of 2.5-3.0.
- the asphalt residue is added gradually while hot (typically about 280°F (138°C) or higher) to the emulsifier solution in a high shear blender. Typically this is done with continuous flow of both liquids through a continuous colloid/emulsion mill. The mixture is blended at a speed and time which produce a small particle size. Typically the majority of the emulsion is in the range of about 10 micrometer to about 60 micrometer average diameter on a weight basis.
- modifying polymers which may be included in the asphalt residue include, but are not limited to, styrene butadiene styrene block copolymer (SBS) , styrene isoprene styrene block copolymer (SIS) , ethylene vinyl acetate copolymer (EVA) , ethylene methacrylic acid copolymer (EMA) , ethylene acrylic acid copolymer (EAA) , or a combination of two or more of these compounds .
- SBS styrene butadiene styrene block copolymer
- SIS styrene isoprene styrene block copolymer
- EVA ethylene vinyl acetate copolymer
- EMA ethylene methacrylic acid copolymer
- EAA ethylene acrylic acid copolymer
- Break control agents will not usually be needed or desirable in the compositions of the invention. However, it should be understood that minor amounts of conventional break control agents could be used in the inventive formulations to fine tune the break times for specialized applications. Viscosity control agents such as CaCl 2 or NaCl also may be used in the inventive formulations in some cases .
- the formulations of the invention are preferably used in road repair applications such as chip seal applications and spray seal applications such as described in US Patent Nos. 5,474,607 and 5,518,538.
- road repair applications such as chip seal applications and spray seal applications such as described in US Patent Nos. 5,474,607 and 5,518,538.
- preferred emulsions without break control agents will usually break to a large extent in 30 seconds or less in order to achieve high area % coating on the stone after the water wash.
- the preferred emulsions are storage stable for at least one week as determined by passing the sieve test. More broadly than the VIM-65 test there is a need for faster breaking chip seal emulsions for road repair applications in colder regions or areas subject to impromptu rain showers.
- the fast breaking chip emulsions are also attractive for roofing applications commonly done with hot tar thereby eliminating the safety and environmental disadvantages of hot tar.
- the emulsions can be spray applied as fast setting asphalt coatings, for instance on concrete pipe or on automobile underbodies with lower safety or environmental concerns than hot applied or solvent-based asphalt coating systems .
- Asphalt emulsions meeting ASTM D 2397 standards for cationic rapid set emulsion CRS-2 were prepared using the emulsifiers commonly used for chip seal or slurry seal applications and amounts set out in Table 1.
- Use level and Asphalt residue are the respective weight percentages of emulsifier (100% active) and asphalt in the final emulsion.
- the emulsifiers were added as emulsifier solutions in water (solution pH 2.5-3.0 adjusted with
- the emulsions were tested in accordance with VIM-65 and the stones coated thereby inspected for coating effectiveness.
- the coating %, estimated by inspection, was recorded and is also reported in Table 1.
- Tall oil fatty acid-diethylenetriamine (TOFA- DETA) amidoamines containing a significant amount of monoamidoamine were then prepared at different ratios of TOFA:DETA as indicated in Table 2.
- the emulsifiers had a residual acid value of 4.2.
- the ratio of monoamidoamine to diamidoamine (Mono/Di) was in the range of 1.8-2.2.
- emulsifiers designated E and F were prepared by post addition of TOFA to Emulsifier B to provide acid values of 6.5 and 8.5, respectively.
- An emulsifier designated G was prepared by post addition of TOFA to Emulsifier C in an amount to provide an acid value of 8.5.
- the amidoamine emulsifiers prepared in Example 2 were used to prepare emulsifier solutions with mineral acid (HC1) and water at 140-145°F (60-63°C) .
- the mineral acid was added in intervals and the pH noted. In all cases the mineral acid was added until a stable emulsifier solution pH of 2.5 - 3.0 was obtained.
- the emulsifier solutions were mixed for at least 15 minutes (20-25 minutes for the Emulsifier A solution) to assure complete or maximum dissolution of the emulsifier.
- Asphalt emulsions were prepared from the various emulsifier solutions using varying amounts of AC10 asphalt residue and varying use levels as shown in Table 3. The emulsions were prepared using a Charlotte G5 colloid mill in the manner described in Example 1.
- the coating % results show that the TOFA-DETA emulsifier gives exceptionally good performance, which can be optimized by careful adjustment of asphalt residue amounts, emulsifier use levels and emulsifier use levels.
- the Examples 3-24 and 3-25 fully met the requirements of VIM-65 without emulsion destabilizing ingredients. The emulsions above all passed the sieve test for storage stability.
- Example 1 TOFA-DETA emulsifiers were tested at various use levels for both % coating under the VIM-65 test and for % asphalt washed off during the VIM-65 test.
- AC10 asphalt was used except for Examples 4-1 and 4-6, where a 60/40 weight basis blend of AC20 and AC5 asphalt was used to approximate the characteristics of AC10 asphalt. Results are given in Table 4.
- Sample 6-2 is a commercial TOFA-DETA imidazoline emulsifier.
- Emulsions were prepared and tested as in the previous examples at an emulsifier use level of 0.225 wt%. Except as indicated in Table 7, the emulsions were prepared from AC-10 asphalt. All of the emulsions passed the sieve test. Results are given in Table 7.
