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.
