沥青混合料骨架特征影响因素的研究

Study on the Skeleton Properties of Asphalt Mixtures

研究粗集料级配和混合料级配对骨架特性的影响 ,提出粗细集料分界筛孔的通过百分率是确保合理骨架的关键。

The influence of coarse aggregate gradation and mixture gr adation on s keleton properties was investigated in this paper. According to the test results , it was found that the percent passing the sieve of dividing coarse and fine ag gregate is the key factor to ensure right skeleton.
