Microcomputer Based Procedure for Load-Zoning Determination on Low-Volume Roads

摘要

A computerized procedure, LOADRATE Version 2.0, for the structural evaluation of light pavement structures has been developed by the Texas Transportation Institute. The report describes the improved version of the LOADRATE program, its User's Guide, and its applications with case studies. The LOADRATE program is a nondestructive procedure which uses data obtained from the Falling Weight Deflectometer (FWD) or the Dynaflect to evaluate the pavement condition. The LOADRATE 2.0 can be used to predict the remaining life of pavement sections, and it also provides estimates for allowable axle loads for test sections. In addition, a capability of making temperature and moisture corrections for the base course modulus is also added to the program. Case studies are provided to demonstrate the use of the LOADRATE procedure for structural evaluation and load-zoning of light pavements.
