Abstract

The invention relates to an asphalt modifying assistant and belongs to the technical field of assistants. The asphalt modifying assistant contains the ingredients in parts by weight: 15-21 parts of SBS (Styrene Butadiene Styrene block polymer) thermoplastic rubber, 15-25 parts of UPVC (Unplasticized Polyvinyl Chloride), 5-12 parts of CPVC (Chlorinated PVC) and 5-8 parts of kaolin. According to the asphalt modifying assistant, the assistant for modifying assistant is prepared from SBS thermoplastic rubber, UPVC and CPVC, the characteristics of all ingredients are integrated, advantages are enhanced, and disadvantages are avoided, so that the comprehensive performance of the assistant is improved; the asphalt modifying assistant has the characteristics of high-temperature resistance, low-temperature resistance, wet-slippage resistance, crack resistance and long life. Due to the addition of UPVC, CPVC and kaolin, UPVC, CPVC and kaolin mutually generate synergistic effects, and Al and Si ions generated from the decomposition of kaolin play a role in polarizing other ions, so that the shrinking percentage of UPVC and CPVC is increased, the plasticity and viscosity of the assistant are improved, and the anti-corrosion property of the assistant is improved jointly by UPVC, CPVC and kaolin.

Description

technical field [0001] The invention belongs to the technical field of additives, and in particular relates to an additive for asphalt modification. Background technique [0002] The asphalt steel bridge deck pavement structure is a thin layer of asphalt pavement (usually 5-10cm) paved on the steel bridge deck. Sex and other aspects play a vital role. [0003] Most of the currently used asphalt binders for bridge deck pavement are epoxy asphalt, or composite modification of rubber powder and SBS (styrene-butadiene-styrene block copolymer), or rock asphalt and lake asphalt Composite modification of road petroleum asphalt. [0004] As an excellent asphalt modifier, SBS can improve the high and low temperature performance of asphalt to a certain extent. However, if it works alone, the dosage is usually large, and its price is high. More workers hope to find its substitute. [0005] Therefore, it is necessary to develop a new type of SBS asphalt modification additive....
