级配碎石基层在渝湛高速公路中的应用

依托渝湛高速公路粤境段工程，选用三种不同的结构组合方式进行了级配碎石基层的应用。根据材料特性采取了有针对性的施工工艺，通过弯沉、抗压回弹模量、变形模量以及压实度的检测，对施工方案进行了验证，并对级配碎石基层的养护管理进行了分析。

Application of Graded Crushed Stone Base on Yu-Zhan Expressway

Relying on the construction of Yu-Zhan expressway project in Guangdong province China,three different kinds of structure combination models have been carried out at the application for matching unbound graded aggregate base;corresponding technology of construction have been adopted according to the material characteristics;the method statement has been checked by deflection value,compressive resilient modulus,deformation modulus and compressive density;analysis on the maintenance management of unbound grade...
