Material of Road Performance Research on Polymer-cement Concrete of the Permeable Base

摘要

Polymer-cement concrete of the permeable base (PCPB), is a new permeable base used in pavement mainly because it applies modifying agent to concrete and improves the quality of it. The priority exists especially in the application as the material of drain water permeable base in which the semi-rigid type base can not be competitive. Through a lot of experiments, we can get the conclusion that PCPB has a better performance when being pressed, folded. It can stand more load than other material. At the same time, the ratio of pressive strength and rupture strength has the tend of decrease. But these are only superficies. In order to explain this problem, and to provide the theoretical bases, this paper aims at comparing the endurance character between PCPB and other materials and uses the calculation of mechanics to find out the theory.
