Embodiment 1

[0012] A method for preparing a composite epoxy asphalt pavement material. The preparation method includes the following steps: (1) The temperature of the reaction kettle is set to 100°C, and 50kg of coal tar pitch is added to the reaction kettle, and stirred with a stirring paddle at 100°C. While stirring, add 24kg of phenolic resin, 15kg of bisphenol F epoxy resin, and 12kg of benzoic anhydride. After the addition is complete, stir evenly at a stirring speed of 80rpm and a stirring time of 5h; (2) Add Stearic acid diethanolamide is 4kg, the stirring speed is 80rpm, and the stirring time is 2h; (3) The aluminum carbonate powder is ball-milled to 250 mesh with a ball mill; (4) 7kg of the 250-mesh aluminum carbonate powder is added to the reaction (5) After stirring evenly, keep the reaction kettle warm for 3 hours to prepare the composite epoxy asphalt pavement material.

Embodiment 2

[0014] A method for preparing a composite epoxy asphalt pavement material, the preparation method comprising the following steps: (1) The temperature of the reaction kettle is set to 100°C, 55kg of coal tar pitch is added to the reaction kettle, and stirring is carried out at 100°C with a stirring paddle, While stirring, add 27kg of phenolic resin, 16kg of bisphenol F epoxy resin, and 9kg of benzoic anhydride. After the addition is complete, stir evenly at a stirring speed of 80rpm and a stirring time of 6h; (2) Add Stearic acid diethanolamide is 3kg, the stirring speed is 80rpm, and the stirring time is 1h; (3) The aluminum carbonate powder is ball-milled to 250 mesh with a ball mill; (4) 5kg of the 250-mesh aluminum carbonate powder is added to the reaction (5) After stirring evenly, keep the reaction kettle warm for 3 hours to prepare the composite epoxy asphalt pavement material.

Embodiment 3

[0016] A method for preparing a composite epoxy asphalt pavement material. The preparation method includes the following steps: (1) The temperature of the reaction kettle is set to 100°C, and 53kg of coal tar pitch is added to the reaction kettle, and stirred with a stirring paddle at 100°C. While stirring, add 29kg of phenolic resin, 17kg of bisphenol F epoxy resin, and 6kg of benzoic anhydride.

Abstract

The invention relates to a composite epoxy asphalt pavement material and a preparation method thereof. The composite epoxy asphalt pavement material is composed of following components in parts by weight: 50-55 parts of coal tar asphalt, 24-29 parts of phenolic resin, 15-17 parts of bisphenol F-type epoxy resin, 3-5 parts of stearic acid diethanolamide, 6-12 parts of benzoic anhydride and 5-9 parts of aluminum carbonate. According to the composite epoxy asphalt pavement material, the composition materials are heated and fused, agitated, crushed and reacted to prepare the composite epoxy asphalt pavement material; the prepared composite epoxy asphalt pavement material has good corrosion resistance and heat resistance; the composite epoxy asphalt pavement material serves as a bonding layer so that the corrosion stability and the heat stability of a road can be improved.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a composite epoxy asphalt pavement material and a preparation method thereof. Background technique [0002] Asphalt pavement is a widely used pavement material. Asphalt materials can resist the damage caused by vehicles and pedestrians to the road surface, making the road surface more smooth, durable and waterproof. There are many applications on urban arterial roads, highways and other roads. With the prolongation of the service time of asphalt pavement materials, some chemical substances will corrode the asphalt materials, and the asphalt materials will have a certain loss. In addition to the corrosion of chemical substances, in some areas that are exposed to high temperatures all the year round, if the epoxy asphalt pavement material is kept in a high temperature environment for a long time, the asphalt material will be deformed. [0003] To reduce th...
