高速公路沥青砼路面破坏的原因包括内因(材料、结构)与外因(荷载、自然气候、水文地质)及施工工艺等多种因素。本文结合渝昆高速水(富)～麻(柳湾)、昭(通)～待(补)、嵩(明)～待(补)公路在管养过程沥青砼路面损坏原因进行分析,并对沥青砼路面损坏养护进行探讨。 The causes of highway asphalt concrete pavement damage include internal factors (material, structure) and external factors (load, natural climate, hydrogeology) and construction technology and other factors. In this paper, the causes of damage to asphalt concrete pavement during the process of tube maintenance are analyzed based on the combination of Yu-Kun high-speed water (rich) ~ hemp (Liuwan), Zhao (pass) Damage Maintenance of Asphalt Concrete Pavement.
