Careful and detailed analyses were made on the causes for nonloading cracks in semirigid road pavements from the aspects of the subbase course,base course and bituminous surface course of a highway to discover the main factors causing these cracks.

本文通过从路面的底基层、基层和沥青路面三个方面对半刚性路面非荷载性裂缝产生的原因进行了细致分析，找出了裂缝产生的主要因素，并从设计和施工角度提出了一些减少裂缝、延长路面使用寿命的方法。

On the basis of analytical result, we put forward the valid measure that improve the shear strength of asphalt mixture.

并在分析的基础上，提出了相应的提高沥青混合料高温抗剪性能的有效措施。

Through comparing the relation of APA test and shearing test, it put forward the maximal to allow shearing strain of RSCH test:?max, the maximal repetitive shearing times: Nmax and minimum to allow APA rutting dynamical stability, which is comparatively suitable to examine the high-temperature performance of the asphalt mixture.

通过比较APA 试验与剪切试验的关系，提出采用RSCH 试验最大允许剪切应变γmax、最大重复剪切次数Nmax 以及最小允许APA 车辙动稳定度，来检验沥青混合料的高温性能是较为合适的。

Therefore, it was necessary to study the shearing test standards for different size of asphalt mixture. The test parameters, shearing stress coefficient for different nominal size were determined.

为此，对适应不同公称粒径的沥青混合料抗剪试验标准进行了探讨，并确定了适用于不同公称粒径的试验参数和剪应力系数。

Therefore,it was necessary to study the shearing test standard s for different size of asphalt mixture.

为此，对适应不同公称粒径的沥青混合料抗剪试验标准进行了探讨，并确定了适用于不同公称粒径的试验参数和剪应力系数。

There are basically two different kinds of asphalt shingles for you to choose from when you need a new roof put onto your home.

基本上有两种不同的沥青瓦给你选择，当你需要一个新的屋顶推出自己的家。

They cost about twice as much as asphalt shingles.

它们的成本约两倍之多沥青油毡。
