Description |
A large percentage of pavement networks are reaching the end of their serviceable live. The pavement management system (PMS) is used to determine whether pavement is in need of rehabilitation. The U.S. Federal Highway Administration investigated new measures to improve the PMS system in order to "establish a reliable measure of the structural condition of all bound pavement layers above the unbound base layer as it deteriorates over time." The Traffic Speed Deflectometer and Rolling Wheel Deflectormeter both showed promise in achieving this goal. This report summarizes the study and its results, and is meant a guide for pavement management engineers and pavement investment decision makers. |
