N2 - The objective of this paper is to present a quantitative decision-support process for selecting nondestructive testing (NDT) technologies to evaluate critical characteristics during asphalt pavement construction. The literature lists mix segregation, in-place compaction, smoothness, temperature segregation, layer thickness, layer bond, and pavement modulus as critical characteristics governing quality pavement construction. Available technologies that measure one or more of these characteristics are identified for unique attributes of test measure, test portability, complexity, test time, environmental limitations, reliability, approved test protocols, training, and cost. A quantitative ranking system determines the most appropriate NDT technologies for quality-assurance measurement. A case study selection is demonstrated uniquely for one agency to measure predefined critical characteristics of in-place compaction, thermal segregation, and modulus using three NDT technologies: infrared thermography, ground penetrating radar, and the portable seismic pavement analyzer. Results from field testing reveal additional aspects of pavement quality measurement beyond traditional density and smoothness measurements.
