摘要
结合深圳已施工的低噪声透水沥青路面典型工程,从原材料选择、混合料配合比设计、施工控制及其注意事项、养护管理等方面介绍了低噪声透水沥青路面在湿热地区市政道路中的应用。实践表明,低噪声透水沥青路面可以大幅度提高行车安全,排水、降噪和降低城市热导效应,在南方湿热地区极具应用前景。在湿热地区应用该技术主要须解决低噪声透水沥青路面水稳定性和热稳定性两大问题,而高粘度改性沥青的使用及其技术指标的确定是保障该技术稳定性的关键,同时还应进一步加强材料技术指标在南方湿热地区的区域性研究。
This paper introduces the application of low-noise porous asphalt pavement in the municipal roads of hot and humid area from the aspects of the raw material selection,mixture mixing ratio design,construction control,the points for attention and maintenance management in a constructed low-noise porous asphalt pavement project of Shenzhen.The practice shows that the low-noise porous asphalt pavement can greatly improve the driving security,drain off water and reduce the city heat island effect with the very applicable prospect in the southern hot and humid areas.This technology used in the hot and humid area can mainly solve two great problems of water stability and thermal stability of low-noise porous asphalt pavement.And the use of high viscosity modified asphalt and the determination of its technical indexes are the key to guarantee the stability of this technology.Also it is necessary to further strengthen the regional study of material technology index for the southern hot and humid areas.
