Paper Abstract

A review is presented of past and current technology used to measure pavement deflection. The configuration for an improved system for deflection measurement which is currently under development is presented. The rolling wheel deflectometer (RWD) based on scanning Lidar profiling is described and rationale and proposed procedures for RWD use and data analysis are presented. Also included are projected calculation procedures for backcalculation of layer moduli from a rolling wheel load.
