Indoor Study on Road Performance of Macromolecule Polymer Bitumen Waterproof and Cohesive Layer (PCMA)
Abstract:
The quality of waterproof and cohesive layer determines the service life of bridge deck pavement. Conventional modified bitumen bonding layer exits some deficiencies that its shear strength is low, construction process is complexity and it need to spread gravel. In order to solve the problem, the new type of waterproof and cohesive layer called PCMA is developed and researched. Through the indoor test study on road performance of the PCMA, the results shows that PCMAs shear strength, drawing stress and fatigue life are significantly higher than other waterproof and cohesive layer. It is especially suitable for hot and humid regions.
