Definitions

  • This invention relates to a polymer modified bitumen (petroleum-asphalt) composi ⁇ tion and a process for the preparation of this composition.
  • the modification of mineral oil bitu ⁇ mens is carried out for improving certain substance-speci ic properties (characteristics) and is above all aimed to extend the tempera ⁇ ture range of applicability.
  • the use of mineral oil bitumens in road construction and insulation is limited thereby that the bitumen becomes brittle (rigid), fragile at lower temperatures, whereas it is softened and looses its solidity and bonding strength at elevated temperatures.
  • the extending of the range of the plastic behaviour of petroleum bitumens can be achieved by the addition of various native and synthetic polymers having a high molecular weight such as the native and synthetic rubber, polyolefines , ethylene/viny1 acetate copoly- mers and the styrene/butadiene, i.e. so- called "SBS" type copolym.ers.
  • SBS type block polymers has not only economical limits but, in additim to the improvement of some properties of application techniques of the bitumen, other technical characteristics are i ⁇ favourably influenced by this modification, e.g. , together with an increase in the cold flexibility, the strength and similarly the resistance to penetration are decreased, particularly at higher temperature.
  • SBS copolymers in a higher proportion seems preferable for the behaviour of the substance at both low and elevated tempera ⁇ tures, the high-grade increase in the viscosity of the composition is unfavourable since it deteriorates the workability and treatment.
  • the quality of starting bitumen has also to be considered ⁇ thus, on modification several viewpoints should be made valid.
  • the aim of the present invention is to develop and prepare a bitumen composi ⁇ tion, by the use of which the properties of the bitumen/polymer mixtures can be modified to a great extent simultaneously keeping the favourable parameters constant by using a cheap additive and, in addition, the bitumen (obtained) can be utilized for both road construction and insulation purposes as well .
  • the modified composition according to the present invention comprises 75-95 parts by weight of mineral oil bitumen, 2-15 parts by weight of styrene/butadiene block polymer, 1-15 parts by weight of vegetable oil, a mixture thereof or regenerated vegetable oil, 0-30 parts by weight of paraffinic, naphthenic or aromatic mineral oil derivatives and 0-25 parts by weight of mineral flour.
  • the process of the invention for the preparation of a modified bitumen composi ⁇ tion comprises adding 0-30 parts by weight of paraffinic, naphthenic or aromatic mineral oil, 2-15 parts by weight of styrene/butadiene block polymer, 1-15 parts by weight of vegetable oil, a mixture thereof or regenerated vegetable oil to 75-95 parts by weight of mineral oil bitumen at a temperature between 170 C and 190 C under vigorous stirring, stirring the mixture at the defined temperature for at least 30 minutes and optionally mixing at most 25 parts by weight of mineral flour with a particle size below 0.1 mm thereto.
  • the bitumen (petroleu -aspbal ) used had a ring-and-ball softening point of 40-60 °C, a penetration of 40-200x10 mm at 25 C, a breaking point (Traass) between -5 C and -15 C and an asphaltene content of 8-15 % by weight.
  • the SBS copolymers suitable for the purposes of this invention had a styrene content of 20-40 % by weight and a molecular weight between 100,000 and 300,000.
  • the mineral oil derivative used had a flash point above 150 C, and a viscosity between 10 and 100 mm /s measured at 40 C. Such types are e.g.
  • the vegetable oil means both drying and semi-drying oils, however, animal fats may also be used.
  • animal fats may also be used.
  • the oils pressed from oily seeds linseed oil, as well as the oil of sunflower, soybean, rape, pumpkin seed, sesam, olive, fish, maize, linseed oil and regenerated oils with a solidification point between -10 C and -20 C and an iodine number of 90-190 may be mentioned.
  • Hog's fat, beef tallow and wool fat are useful animal fats.
  • the vegetable oils or animal fats improve the behaviour of the modified bitumen system at a low temperature without unfavourably influencing its properties at elevated temperatures j they significantly improve the stability of bitumen composition, decrease its propensity to the separation otherwise observed, which occures in the case of co- polymer-modified bitumens.
  • the presence of vegetable oils improves the adhesion of bitumen compositions to the breakstone used in the road construction and, on the other hand, the adhesion of the bitumen compositions to the carrier textile (web) of roofing felt.
  • the mineral oil additives also influence the properties of modified bitumens to a great extent, i.e. the mineral oil additives are effective not only as diluting agents or solvents but, depending on their composi ⁇ tion, they influence the micro- and macro- structure of the composition as well.
  • bitumen used for road construction with a softening point of 48 C, breaking point of -14 C, penetra ⁇ tion of 7.8 mm and an asphaltene content of 14.5 ._ by weight

When examined at -20 C, the retention of particles (grains) which is characteristic of the adhesiveness, is about 95 % .
  • the strength of the asphalt prepared by using the modified bitumen accord ⁇ ing to the composition of the Hungarian standard No. MSZ 07-3210 is better than that of the asphalts prepared with known modified bitumen; and it shows particularly excellent features in the course of investiga ⁇ tion of repeated loading at a higher temperature or adhesiveness at a low temperature.
  • a modified bitumen was prepared by using the bitumen and polymer of the above-mentioned quantity and quality without naphthenic oil fraction adn sunflower oil.
  • the product had a softening pointz of 80-85 C and break ⁇ ing point of -14 C. After a storage of 72 hours at 180 C a sample was taken and the SBS polymer was significantly enriched in the upper part of the sample, a phenomenon indicating that the compatibility of the bitumen and polymer was not adequate.
  • the strength of asphalt prepared by using this modified bitumen possessed poorer properties at normal temperature than the bitumen according to the invention.
  • the grain-retain ⁇ ing ability of the binder was found to be about 50 % at -20 °C.
