Study of APP Modified Asphalt Felt in Preventing Cracks of Asphalt Concrete Covering Layer on Pavement

摘要

On the base of the conprehensive analysis of the reason and the measures to prevent the reflection cracks about airport asphalt concrete pavement covering layer, and through indoor fatigue experiment, on-site construction experiment and following observation on the construction engineering using APP modified asphalt felt as splitproof layer, the article analyzes and studies technological role and effect of APP modified asphalt felt preventing reflection cracks, puts forward problems to be studied in the future, and provides effective way of solving the problem on reflection cracks.
