Description
The present invention relates to a kind of semi-rigidity bituminous concrete material composition and manufacture method thereof.
Country often drives increase of goods traffic flow and vehicle load and strengthens in process of economic development along with industrial development, the load that covering of roadway bore also strengthens thereupon.Past, the bituminous (bitumen)concrete pavement was to adopt hot-mixed asphaltic concrete in pavement engineering construction, and by the mode of gravity stratification spreading, and the bituminous concrete spreading is closely knit and reach the design strength of expection.The asphalt pavement of laying through mode thus is called Flexible Pavement, and Flexible Pavement has preferable flexibility, can obtain more comfortable road sense.But because the inborn restriction of material, the hot asphalt paving easily produces phenomenons such as rutting deformation, crack and surface slip because of wheel weight destroy pavement structure.
Because of cement concrete is used in road pavement, this kind cement concrete paving was called the rigid pavement afterwards, and the mechanical failure of covering of roadway reduces thereupon.But because the intensity and the rigidity of cement concrete are higher, vehicle travels on the rigid pavement and jolts greatlyyer, and the comfortableness of travelling is relatively poor, and the higher and required operating technique of engineering cost is difficult, and the maintenance work in paving is difficult, therefore becomes the shortcoming that cement concrete is used in the paving.
Traditional hot-mixed asphaltic concrete has interpolation cement occasionally, but be to use mostly as stopping composition, cement there is no the agglutinating function in bituminous concrete, and its addition upper limit is about 10-15%, adds that the mechanical strength to bituminous concrete there is no significant lifting after the cement.In the known technology, once used and accounted for the addition material of the cement of pellet weight ratio 0.5-2%, found increase in the test-results, bituminous concrete parcel property reduction and stationary value increases and fluidity value becomes big with the cement addition as emulsified bitulith.
Hence one can see that, if with the stopping composition of cement as emulsified bitulith, though can increase a little stationary value or intensity, but generally speaking to bituminous concrete, add cement will make fine granules in the bituminous concrete as stopping composition filling effect, because of cement is reduced by the moisture aquation, its hole is increased, and the ability of erosion of opposing moisture and paving displacement is reduced.Therefore with regard to bituminous concrete improves material, still have improved necessity.
In above-mentioned background of invention, all there are some problems in traditional Flexible Pavement and rigid pavement material, therefore the present invention proposes improvement at its shortcoming, cement is combined the sandstone pellet again through special processing with emulsified bitumen, and develop the Flexible Pavement material that can be used on the normal temperature construction and have higher-strength, and with this surfacing material called after semi-rigidity bituminous concrete (Semi-Rigid Asphalt Concrete).
Another object of the present invention is to be to disclose a kind of existing cement concrete mix plant that utilizes, and reaches the method that the rigid pavement construction machinery carries out material manufacturing and construction.
According to above-described purpose, the present invention provides a kind of employing cationic emulsified bitumen, Type-I cement, F-Type and moulds agent (Superplasticizer), Xylo-Mucine (Na-CMC by force, Na-Carboxymethyl Cellulose), the sandstone pellet of calcium chloride, stone flour and code name III d, IV b and VII a grating is raw material, carries out material mix, cast and maintenance and the semi-rigidity bituminous concrete that forms according to the method for cement concrete manufacturing.
This semi-rigidity bituminous concrete is earlier F-Type to be moulded agent by force to inject emulsified bitumen stirring formation one mixed solution, after the solution of calcium chloride that will mix up in advance and Na-CMC is poured into and is continued stirring until evenly then, pour cement, stone flour and fine granules into mix in regular turn again, then pour Coarse Aggregate again into, when mix can discharging after evenly pour into a mould and maintenance after open the use, needn't be again through manufacturing processedes such as high temperature mix and roll extrusion.
The present invention changes the traditional asphalt concrete fully and must utilize the manufacture of high temperature mix and compaction in layers and heat to mix the kenel that worker's method is constructed.
In addition, the semi-rigidity bituminous concrete that the present invention discloses, not only mix and construction easily, and can replace traditional asphalt concrete heat and mix worker's method, also the waste gas public hazards be can reduce, more can utilize existing cement concrete mix plant, and the rigid pavement construction machinery material manufacturing and construction carried out.
Because semi-rigidity bituminous concrete has factory's manufacturing or job mix, pours into a mould and exempt from the characteristic of compacting, therefore construction more is not subjected to the restriction of landform and landforms, also is not subjected to the influence of weather during construction.And on the Ordinary Rd road surface, pavement, paving, parking lot, basic unit's soil ground improvement, roof water-proof shop layer, cover worker's version non-skid finish, paving, sports center, with pavement engineering maintenance or the like, all can utilize this semi-rigidity bituminous concrete to lay.Therefore, semi-rigidity bituminous concrete is an invention of very having practicality and a commercial value in fact.
The key that semi-rigidity bituminous concrete can be stablized mixing, produce and construct in the mix stage, be to be to use F-Type to mould the buffer reagent of agent by force as emulsified bitumen and cement and pellet, make emulsified bitumen after ease is lost the part free-water, can not make suspension be reduced into asphalt cement and water at once; And when utilizing cement asphalt mastic dehydration degree high more, the high more characteristic of viscosity then, rheological (Rheological properties) with control sandstone pellet can not isolated it, and then make the viscosity of semi-rigidity bituminous concrete can when mix, not produce obstruction, the present invention all can fully grasp because of material physical properties and chemical property relevant in the semi-rigidity bituminous concrete, and the mix technology also can obtain control, so semi-rigidity bituminous concrete can enter and produces in batches and stage that practice is utilized.

Fig. 2 describes in the preferred embodiment of the present invention, the fabrication process flow figure of semi-rigidity bituminous concrete.At first need the mixed solution that cationic emulsified bitumen and F-Type mould agent by force stir (step 41), if in the process that stirs, produce some milks, then must proceed the action of mix, till this milk all disappears (step 42), then pour the calcium chloride Na-CMC solution that modulates in advance again into, allow mix equipment proceed mix (step 43) then.And calcium chloride Na-CMC solution is that calcium chloride is dissolved in the Na-CMC solution of concentration 1%, more even mix and getting.
Mix evenly back adds Type-I cement and stone flour, make mix equipment continue mix action (step 44), add fine granules after stirring again and continue mix (step 45), just pour Coarse Aggregate at last into and stir (step 46), by the time can discharging pour into a mould and maintenance after stirring, after solid firmly, can provide use, needn't be through the manufacturing processed of high temperature and compacting.The process of semi-rigidity bituminous concrete manufacturing and construction can be carried out in normal temperature, but the order of spice then can not exchange with the proportioning of material, otherwise is difficult to obtain colory semi-rigidity bituminous concrete.
Table 3 is described the comparison aspect stable of semi-rigidity bituminous concrete and hot-mixed asphaltic concrete.Newly mix semi-rigidity bituminous concrete because of having quite good denseness, so the homogeneity of material and stability are all good after cast.In hard part admittedly, be engaged in the test of immersion residual strength at semi-rigidity bituminous concrete with 60 ℃ hot water.Can learn that by table 3 semi-rigidity bituminous concrete of three kinds of gratings still keep about 90% ultimate compression strength, yet hot-mixed asphaltic concrete is lower than 75% after corroding through rigorous environment.
Table 3
| Material | The immersion residual strength | The rutting deformation amount |
| Semi-rigidity bituminous concrete III d grating | 89.24％ | 0.43mm |
| Semi-rigidity bituminous concrete IV b grating | 88.78％ | 1.12mm |
| Semi-rigidity bituminous concrete VII a grating | 97.12％ | 1.36mm |
| Hot-mixed asphaltic concrete IV b grating | 75％ | 7.25mm |
| *Remarks | Soak 60 ℃ with the ratio that does not soak | The 7 day length of time is with 60 ℃ of temperature and 19.4kg/cm 2Pressure, pressure testing 2000 times |
Aspect stable, also can utilize the rutting deformation amount of table 3 to represent.Learn by table 3, at 60 ℃ and 19.4kg/cm
2Pressure condition under, the rutting deformation amount of hot-mixed asphaltic concrete is about 7.25mm during the 7 days length of time; But semi-rigidity bituminous concrete III d, IV b under the similarity condition and VII a grating only have respectively 0.43mm, 1.12mm, with the rutting deformation amount of 1.36mm.The stability of hence one can see that semi-rigidity bituminous concrete be higher than hot-mixed asphaltic concrete really.
Table 4 is testing datas of utilizing degree of collapsing, is doing one aspect the workability relatively at semi-rigidity bituminous concrete and cement concrete.Semi-rigidity bituminous concrete is because of adopting the rigid surface construction equipment, so degree of collapsing must be controlled at 10cm or be lower than 10cm.If desired degree of the collapsing 3-8cm of construction compares with the rigid surface, semi-rigidity bituminous concrete of the present invention as can be known is good than the cement concrete workability of rigid surface.Again because semi-rigidity bituminous concrete is after adding Na-CMC, can cause the delayed coagulation of cement, so the presetting period of semi-rigidity bituminous concrete may be longer slightly than cement concrete, is about 3.5-4 hour, so when construction, apart from bigger elasticity is arranged, its degree of collapsing loss was also less during the transporting of material.Therefore semi-rigidity bituminous concrete has convenience in the work than hot-mixed asphaltic concrete and cement concrete aspect the workability.

| Grating | Ⅲd | Ⅳb | Ⅶa | The rigid surface |
| Degree of collapsing (centimetre) | 4-9 | 6-12 | 8-13 | 3-8 |
Table 5 is at semi-rigidity bituminous concrete and cement concrete, and hot-mixed asphaltic concrete does one relatively aspect intensity.Semi-rigidity bituminous concrete is because of adding cement in material, and the decorating film that hydrated cementitious produces also can increase and sandstone pellet agglutinating effect except that bearing the loading.As shown in Table 5, its strength ratio hot-mixed asphaltic concrete of semi-rigidity bituminous concrete can exceed about 2-3 doubly, and that modulus of elasticity is desired only to exceed is about about 20%, so semi-rigidity bituminous concrete is one to have and can bear traffic loading, and has the surfacing material with the close flexibility of bituminous concrete.
