Problems solved by technology

If epoxy asphalt is used as the bonding material, since the old epoxy asphalt concrete has been completely cured, the new epoxy asphalt cannot penetrate into the cured epoxy asphalt to produce bonding force, which also leads to bond failure

The binding material disclosed by the invention can improve the binding performance thereof, and increase the durability of repair of epoxy bituminous concrete paved layers.

Description

technical field [0001] The invention belongs to the field of asphalt concrete, and relates to a bonding material, in particular to a bonding material used for an asphalt concrete base surface and a preparation method thereof. Background technique [0002] With the development of my country's transportation industry, the number of bridges is increasing, especially the proportion of long-span bridges is increasing. Epoxy asphalt concrete is widely used in bridge deck pavement because of its excellent high temperature stability, low temperature crack resistance, durability, high strength, and good durability. Bridge deck pavement is directly in contact with the external environment and vehicles, and its quality directly affects the durability and performance of the bridge, as well as the comfort and safety of driving. Many bridge decks are paved with asphalt concrete or epoxy asphalt concrete, and the pavement layer has been damaged to varying degrees. These damages mainly in...
