现有路缘石通常有两种形式，一种为普通混凝土预制，一种为石材加工，它们均为不透水材料。路缘石下的基础一般为细实混凝土，也为不透水材料。由于路面底层为厚度较大的夯实基础层，为不透水层，加之路缘石及下部基础均不透水，导致路面层内部水无法下渗或通过路缘石及其基础排出。路面结构层以及面层与基层界面的水不能顺畅排出路面结构，是路面产生早期损害的诱因之一。基于一项专利技术，设计了一种新型混凝土路缘石。新型路缘石可排出路面层内部水，且与通常采用的路缘石在造价上差异不大。 There are two forms of existing road stones, one is prefabricated for ordinary concrete and one is for stone processing. They are all impervious materials. The foundation under the edge of the road is usually fine concrete, and it is also an impermeable material. Because the pavement bottom is a thick rammed foundation layer, which is impervious to water, and the curb and the underlying foundation are impervious to water, resulting in the water in the pavement layer can not be infiltrated or discharged through the curb and its foundation. The surface structure of the pavement structure and the interface between the surface layer and the base layer can not smooth out the pavement structure, which is one of the causes of the early damage of the pavement. Based on a patent technology, a new type of concrete pavement stone is designed. The new road edge Shi Ke discharged the inner water of the pavement, and was not very different from the commonly used road stone.
