NONCONTACT, NONDESTRUCTIVE DETERMINATION OF PAVEMENT DEFLECTION UNDER A MOVING LOAD. FINAL REPORT

A feasibility study of a proposed method for measurement of highway pavement deflection under a moving load is presented in this report. The proposed method utilizes non-contact displacement sensors to measure pavement deflections at speeds up to 50 mph. Anticipated problem areas with this measurement task are discussed and proposed solutions to them are presented along with equipment recommendations to implement the solutions. Test data are presented on an optical sensor of the type proposed for measurement of pavement deflection. A recommendation is made to build a prototype pavement deflection measurement system based on the results of this work.
