摘要
随着交通量和轴载的增加,对路面使用性能的要求越来越高,这也促进了路用土工合成材料产品的不断发展。国内外对土工合成材料应用于沥青路面进行了大量的室内与现场试验及理论分析工作。结果表明,土工合成材料能有效防止各种病害,改善路面的使用性能。对目前土工合成材料在沥青路面结构应用的几种设计方法进行了分析和评价,并根据美国地沥青协会(AI)所提出沥青路面罩面的设计程序,介绍了土工合成材料用于沥青罩面加筋,以减薄罩面厚度的设计方法。
With the growth of traffic volume and axial load, the requirements for pavement performances are higher day by day, and thus many types of geosynthetics products used for road have been developed. The laboratory and field test achievements and the theoretically analytical investigations on improving performance of geosynthetic-reinforced asphalt pavement are evaluated. Those design methods of geosynthetics-reinforce asphalt pavement are analyzed. Furthermore, in accordance with the design procedure for asphalt overlay proposed by the Asphalt Institute in the United States of America, a design method for asphalt overlay with geosynthetics interlayer on cracked pavement is introduced.
