Book Description
A procedure for the nondestructive evaluation of military roads and streets is presented. Nondestructive testing is performed with the Road Rater 2008, an electrohydraulic vibrator which measures the load-deflection response of pavements. From the measured load-deflection response, the dynamic stiffness modulus (DSM) is calculated. Correlations of the DSM to the number of allowable passes of an 18,000-lb single-axle dual-wheel load, determined from conventional destructive testing and evaluation procedures, are used with existing analytical relationships to determine the number of allowable passes the pavement can support, and, if required, the overlay thickness. This report also describes the testing equipment, testing techniques, data reduction procedures, and computational methodology used in developing the evaluation procedures for both flexible (AC) and rigid (PCC) highway pavements. An operator's guide describing the day-to-day maintenance and operation of the NODET is presented in Appendix C.

Book Description
A logical method for pavement evaluation utilizing both nondestructive procedures for structural analysis and pavement condition distress to identify maintenance needs is presented. Alternatives for maintaining desired serviceability are categorized as routine maintenance, major maintenance, rehabilitation, and reconstruction. The alternatives are selected based on levels of the pavement condition index and results of nondestructive testing structural evaluation. A flowchart outlining the decision process of identifying appropriate alternatives is presented. Specific treatments are selected as a function of the pavement type and the severity level of the distress. Keywords: Airfield pavement; Condition survey; Roads and streets.
