Abstract

The invention relates to a seawater-corrosion-resistant bituminous pavement material and a preparation method thereof, and belongs to the technical field of pavement materials. The seawater-corrosion-resistant bituminous pavement material is prepared from, by weight, 10-15 parts of bitumen, 5-20 parts of hemihydrate gypsum, 15-20 parts of Portland cement, 5-10 parts of silicon dioxide, 3-5 parts of silicon carbide ceramic powder, 1-3 parts of glass hollow microspheres, 3-6 parts of paraffin, 6-12 parts of kieselguhr, 20-40 parts of coal ash, 0.5-2 parts of antimold, 0.5-2 parts of a surface active agent and 50-200 parts of water. By means of reasonable combination of the components, the bituminous pavement material has the advantages of being good in seawater corrosion resistance and high in strength.

Description

technical field [0001] The invention relates to a seawater corrosion-resistant asphalt pavement material and a preparation method thereof, belonging to the technical field of pavement materials. Background technique [0002] Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental factors during its use. Therefore, while asphalt concrete has a certain bearing capacity, it must also have good durability against natural factors. That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging and good anti-skid property to ensure asphalt pavement Good service function. [0003] Many roads close to th...
