高等级公路半柔性路面材料性能及施工质量研究

为了探究半柔性路面材料在不同设计孔隙率下的力学性能、稳定性能和疲劳性能,引用最优设计孔隙率对半柔性路面材料进行材料性能验证。结果表明:半柔性路面材料的各项性能优异;随着设计孔隙率的增加,半柔性路面材料的力学性能增加,但会变得更脆,不利于结构的稳定;在实际工程中,通过严格控制原料配比和施工顺序,半柔性路面材料的力学性能可以达到试验效果,路面抗病害能力有较大的提升。

Research on Performance and Construction Quality of Semi-flexible Pavement Material of High-grade Highway

In order to explore the mechanical properties,stability properties and fatigue properties of semi-flexible pavement materials under the different design porosities,the optimal design porosity is quoted to verify the properties of semi-flexible pavement materials.The results show that the semi-flexible pavement materials have the excellent properties.With the increase of design porosity,the mechanical properties of semi-flexible pavement material increase,but it will become more brittle,and is not conducive to the stability of the structure.In the practical engineering,through the strict control of raw material ratio and construction sequence,the mechanical properties of semi-flexible pavement material can achieve the test effect and greatly improve the anti-disease capacity of pavement.
