摘要
重载作用会造成路面结构的强度破坏及使用寿命的缩短。根据对某沥青混凝土路面的现场勘察试验,认为重载车辆作用是导致路面损害的主要原因,初步揭示了在重载作用下沥青混凝土路面各结构层的应力特点,分析了重载作用下路面病害的原因,并提出了防治措施建议。
Heavy load function can break the strength of pavement structure and short the service life of the asphalt concrete pavement. The main reason of pavement distress is the heavy-duty vehicle function according to the investigation and experiments of a certain asphalt concrete pavement. The failure characteristics and the regularity of the pavement are revealed, the failure reasons of pavement are analyzed and some countermeasures for prevention are proposed.
