沥青路面大修工程中的结构、材料设计研究

A Study of the Design on the Asphalt Pavement Material and Structure for Large-scale Maintenance

本文首先分析了目前沥青路面大修工程的诸多特点,同时探讨了我国目前沥青路面在结构设计和材料设计方面的不足之处,在此基础上提出了更具针对性的大修工程中沥青路面材料设计和结构设计相统一、协调的设计方法。分析认为:在设计之前,应首先对沥青路面所处位置的交通条件、气候条件、水文地质条件、路面原始条件进行详细的调查分析,寻找出导致沥青路面发生病害的主要因素,从而得到控制路面使用性能的主要指标,之后进行完善的路面材料、结构综合设计,对延长沥青路面的使用寿命是十分有效的。

This paper firstly analyses many characteristics of the large-scale maintenance work on the as- phalt pavement and discuss the limitation of the material and structure design on the asphalt pavement in Chi- na. Base on the above discussion, this paper establishes the harmonious and idiographic design method of the material and structure design on the asphalt pavement maintenance work. The fact indicates： The compre- hensive designing of material and structure on asphalt pavement is very feasible and effective after finding the main factors resulted in pavement distress, based on the detailed survey of traffic conditions, climate con- ditions, pavement original conditions and so on.
