路面透水表层临界空隙率研究

Research on Critical Porosity of Pavement Porous Course

采用重正化群方法分析透水表层所形成连通空隙的临界空隙率，并提出一个公式，用以计算透水表层的集料级配，可得到与国外经验相近的结果。

Renormalization group method is used in this paper to analyse the porous surface course critical porosity of the voids which are continuous and connected one another. The aggreate gradation of a porous surface course is calculated by a formula, and get values which are approximate to empirical ones in foreign countries.
