Bituminous concrete for bituminous road road repair

Bituminous concrete is a kind of organic-inorganic composite material composed of high performance cement, special asphalt, water, fine aggregate and admixture, which combines the mechanical properties of cement-based materials and the flexibility of asphalt based materials. The above components are prefabricated into liquid and powder materials in the factory according to their physical state, and the liquid and powder materials can be mixed by special mixing equipment during site construction.

 1. Clean the base surface: In order to slow down the corrosion of environmental water on the concrete and increase the durability, remove or repair the freeze-thaw denudation, aging damage, dew reinforcement, carbonization, honeycomb surface and corrosion parts of all the structural surface on the concrete to make the base surface qualified.
2, material preparation: pour the glue into the bucket, according to the ratio of glue: powder =1: 4, slowly add the powder with the electric stirring rod, stir until there is no caking, the prepared material should be used up before consolidation;
3, construction: when using asphalt mortar as the overall surface layer, the thickness should not be less than 5mm; When the construction area is large, the construction joint or piecewise staggered construction should be left.
