• Abstract:
  Current roadway quality control and quality acceptance (QC/QA) procedures for the Louisiana Department of Transportation and Development ; (LADOTD) include coring for thickness, density, and air voids in hot mix asphalt (HMA) pavements and thickness and compressive strength ; for Portland cement concrete (PCC) pavements. Mechanistic design is based on the moduli of pavement layers. As LADOTD pushes toward ; performance-based specifi cations, new parameters of the pavement must be considered for QC/QA. Non-destructive testing (NDT) devices, ; such as the light weight defl ectometer (LWD) and the portable seismic pavement analyzer (PSPA), Figure 1, provide a non-destructive and ; portable means of quick in-place determination of pavement properties, resulting in an increase in sampling frequency to supplement coring. ; The LWD and PSPA are capable of measuring the in-situ modulus of a pavement layer. The measurements of these devices can either be used ; as a standalone measure or, in most cases, be correlated to other pavement properties. Many researchers have shown good trends between ; measurements of the NDTs and other pavement properties, though variability has shown to diff er from report to report.
