Description

technical field

[0001] The invention relates to the field of asphalt, in particular to a cold-mix asphalt and its preparation method and application. Background technique

[0002] A large number of asphalt is used as the pavement material for highway pavement or bridge deck, but because asphalt is a thermoplastic material, the asphalt pavement material usually adopts a hot-mixing method during the construction process, and the construction process of the hot-mixing method is complicated and often requires large-scale equipment , and consume a lot of fuel; at the same time, the construction process is affected by the climate, the process coordination requirements are strict, the material utilization rate is low, and the waste is serious. Therefore, people gradually turn their attention to the development of cold mix asphalt.

[0003] CN100434479C discloses a kind of SBS asphalt liquid which is a cold-mix repair material for pavement pits and its production process. The SBS a...
