| 摘 要： | 一般认为,只要有足够厚的沥青膜裹附在集料上,就能保证沥青混合料的耐久性.最小的沥青膜厚度被推荐为6～8μm,本文通过不同的沥青膜厚度与沥青混合料老化特性之间的关系,给出一个合理的最佳范围.

| Abstract: | It is generally believed that an asphalt paving mixture should have an adequate asphalt film thickness around the aggregate particles to ensure reasonable durability(resistance to aging) of the mixture.The minimum asphalt film thickness generally recommended ranges from six to eight microns.This study was undertaken to quantified the relationship between various asphalt film thickness and the aging characteristics of the asphalt paving mix,so that an optimum film thickness desirable for satisfactory mix durability could be established. |
