New Practice for Rolling Wheel Load Tests to Evaluate the Structural Performance of Roadway Test Sections with Geosynthetics
1. Scope
This standard practice outlines the requirements associated with the construction and testing of full-scale unpaved and paved roadway cross-sections, with and without geosynthetics, that are built in a controlled manner and trafficked using a rolling wheel load.Keywords

Multiple research and testing efforts currently use large-scale rolling wheel load test devices to determine the performance of geosynthetics in pavement applications; however, difference between test methods and lack of certain types of data collected during construction and testing make it difficult to impossible to adequately compare and/or scrutinize the results. Furthermore, lack of quality assurance and quality control data from construction activities makes it difficult to know whether differences in performance are due to construction and testing variabilities or the geosynthetic. Having clear design targets and allowable limits will improve the accuracy, repeatability, and comparability of performance data from these types of tests.
