本标准实施规程为有意采用土工合成材料加固柔性路面结构骨料基层的路面设计师提供了指南。土工合成钢筋旨在在路面使用寿命期间为交通荷载提供结构支撑。在本指南中，基层加固是指在粒状基层内或正下方使用土工合成材料。当提到土工合成材料时，讨论仅限于土工织物、土工格栅或土工格栅/土工织物复合材料。本标准以前被指定为临时标准PP 46。

This standard practice provides guidance to pavement designers interested in incorporating geosynthetics for the purpose of reinforcing the aggregate base course of flexible pavement structures. Geosynthetic reinforcement is intended to provide structural support of traffic loads over the life of the pavement.For the purpose of this guide, base reinforcement is the use of a geosynthetic within, or directly beneath, the granular base course.When referring to geosynthetics, the discussion is limited to geotextiles, geogrids, or geogrid/geotextile composites.This standard was formerly designated as provisional standard PP 46.
