重交通轴载条件下的复合式路面设计应用与造价分析

Composite Pavement Design Application and Cost Analysis Under the Heavy Traffic Axle Load Condition

高等级公路路面设计应在满足轴载作用的条件下,具备行车舒适、低温抗裂、高温稳定、使用耐久、经济合理的设计功能和使用效益,称之为优化设计。基于柔性路面与刚性路面各自具有的功能和特点,故提出复合式路面结构层的设计与应用问题,因此;通过分析路面结构的受力性质与理论研究,利用各自不同的优点进行路面力学特点的互补,可以更好提高路用性能和提高经济效益。

The high grade highway pavement design should be driving comfort, low temperature crack resistance, high temperature stability, the use of durable, economic reasonable design function and using efficiency under the condition of meeting axial load,So it is called design optimization. Based on the flexible pavement and the rigid pavement each has its own characteristics and functions, So we put forward the design and application ofcomposite pavement structure layer. Therefore, through the analysis of the mechanical properties of pavement structure and theory research, using different complementary advantages in pavement mechanics characteristics, can better improve the road performance and improve the economic benefit.
