Abstract

The invention relates to an antifreeze hard epoxy asphalt pavement material and a preparation method thereof. The antifreeze hard epoxy asphalt pavement material is composed of the following components according to the weight ratio: 28-30 parts of petroleum asphalt, calcium stearate 5-9 parts for vinyl epoxy resin, 18-22 parts for vinyl epoxy resin, 9-13 parts for trimellitic anhydride, 5-6 parts for butyric acid, 4-6 parts for 1-hexene, and 3-5 parts for magnesium chloride. The pavement material is prepared by heating, melting, stirring, pulverizing, heat preservation and other steps of each material component. The prepared pavement material has good frost resistance and high hardness, which can prevent cracking due to cold weather as a road material. phenomenon occurs.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a frost-resistant hard epoxy asphalt pavement material and a preparation method thereof. Background technique [0002] Epoxy asphalt pavement material is used as a bonding layer in roads, and it needs to meet long-term use under various environmental conditions. In the local severe cold area, under the low temperature environment for a long time, the antifreeze performance of the epoxy asphalt pavement material as the bonding layer is very important. If its anti-freeze performance is poor, the road will crack after long-term use, which will affect the smoothness and safety of the road. [0003] In view of the phenomenon that epoxy asphalt pavement materials will crack after long-term use in severe cold areas, it is necessary to improve the antifreeze performance of epoxy asphalt pavement materials. Freeze resistance of pavement materials. Contents of the...
