摘要
牧区道路是一种利用当地材料修建在草原区的小交通量道路。为了选择合适的牧区道路基层结构类型,修建了不同基层类型的试验段和2个试槽,通过承载板法测定了各层顶面的当量回弹模量,利用双层弹性体系理论反算出各层回弹模量。以回弹模量为评价指标推荐了牧区道路基层类型,并对其结构强度进行了评估,完善了牧区道路设计体系。
Pastoral area road is a kind of low traffic volume highway built in grass land. In order to select appropriate base course, four experimental sections of road and 2 testing troughs are built on which equivalent resilient modulus are tested by load plate test, then double layers elastic systems are employed to calculate resilient modulus for each layer. Appropriate base courses are recommended and its structure strength is assessed. Pastoral area road design system has been improved.
