高速公路沥青路面早期破坏防治技术研究

Control Techniques Expressway Asphalt Pavement Early Damage

高速公路沥青路面由于受设计、施工、运营管理、气候环境等多种因素的影响,往往容易产生早期破坏,降低路面使用性能,严重影响了路面的使用寿命。必须从软土地基处理、路基填筑压实度、基层质量等方面,完善沥青面层设计,控制施工质量,加强运营管理,采取多方面综合防治措施,才能尽量避免或减少早期破坏的发生,提高路面的使用质量,延长路面使用寿命。

Because of the influence of design,construction,operation management and climatic environment,early damages frequently appeare on asphalt pavement of expressway,which weaken pavement performance and shorten service life of pavement seriously.Only improving design of asphalt pavement and controlling construction quality in terms of soft soil foundation treatment,subgrade filling compactness and base quality,strengthening operation management and taking comprehensive prevention measures,can early damage be avoided or decreased,service performance of pavement be improved and service life of pavement be prolonged.
