Study on the New Waterproof Bonding Material of Bridge Deck Pavement

摘要

In our country, the waterproof bonding layer destruction is a main reason which lead to bridge deck pavement damage, the effective measure is to solve the weak quality question of bonding material between layers, it is a important quarantee for bridge deck pavement durability. This paper has an in-depth research to pavement performance of synchronization gravel waterproof bond layer, the best dosages of asphalt and gravel have been obtained, and the improving construction method has been put forward. The results shows that the synchronization gravel waterproof bond layer with two apray asphalt and one spread gravel method can solved the weak quality question of interlayer cementing material.
