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.

This report discusses the major principles which can be used to categorize the various nondestructive testing techniques: static deflections, steady state deflections, impact load resistance, and wave propagation. Due to their simplicity and ease of testing, static deflection devices are widely used. The impact testing technique offers an extremely rapid technique for dtermining the dynamic load response characteristics of pavement structures. The wave propagation technique offers promise of providing elastic moduli values for all of the pavement layers. New techniques such as laser devices, light emitting diodes, and photography offer a potential for rapid deflection measurements using full-scale moving loads.
