Description

technical field [0001] The invention relates to the field of traffic engineering materials, in particular to a normal-temperature thermosetting epoxy asphalt mixture used on long and steep expressway slopes and a preparation method and application thereof. Background technique [0002] For the rutting problem of asphalt pavement on long and steep slopes of expressways, the road traffic departments of various countries have done a lot of research work and achieved good results. Usually, SBS modifiers, anti-rutting agents, and recycled engineering plastics are used singly or in combination for the modification of matrix asphalt. These technologies have a considerable effect on improving the high-temperature stability of asphalt concrete. It can better improve the high temperature stability of asphalt concrete. However, for special occasions such as asphalt pavement on long and steep highway sections, traditional thermoplastic modified asphalt mixtures still cannot solve the s...
