Research Development on Trackless Wheel Emulsified Asphalt in China
Asphalt pavement is a multi-layer elastic system structure.Being a tack coat,emulsified asphalt make multi-layers structures a whole stresses system so that the service life of roads was directly affected.However,the ordinary emulsified asphalt is often picked up and contaminated by construction traffic,resulting in poor bonding at the interface.At present,the research on trackless wheel emulsified asphalt is still in the early stage in China.The preparation methods are varied and the test methods are divided,resulting in uneven performance of commercially available products.Based on years of practical experience in highway maintenance projects in Beijing,a literature search to examine the research progress of trackless emulsified asphalt was conducted in China in this study.the failure mechanism,preparation,performance testing,and applications were elaborated.The suggestions were put forward for the research emphasis and development direction of trackless emulsified asphalt in future.
