This proceedings presents a range of timely and important issues related to characterization of pavement subgrade and unbound materials using new analytical and experimental techniques. The papers cover pavement nondestructive testing using the Falling Weight Deflectometer (FWD), High-Speed Rolling Deflectometer, and Spectral-Analysis-of-Surface-Waves (SASW).

Overview

This proceedings presents a range of timely and important issues related to characterization of pavement subgrade and unbound materials using new analytical and experimental techniques. The papers cover pavement nondestructive testing using the Falling Weight Deflectometer (FWD), High-Speed Rolling Deflectometer, and Spectral-Analysis-of-Surface-Waves (SASW). Different methods of laboratory testing such as triaxial and resilient modulus testing are also discussed. The analysis methods include artificial neural network, three-dimensional finite element techniques, linear and nonlinear material response, static and dynamic analysis of material behavior, and backcalculation of layer moduli. The papers cover characterization of pavement surface, base, subbase, and subgrade layers. The depth to bedrock is also considered.
