• Abstract:
  The main objective of this report is to combine the resilient moduli from laboratory testing of base materials with those obtained in the field using nondestructive testing devices. Laboratory tests were carried out in two stages. First, virgin materials from the quarry compacted to optimum moisture content were tested. In the second stage, similar base materials were retrieved from in-service roads. Specimens were prepared and tested at the corresponding field densities and moisture contents. Nondestructive tests were performed with the Falling Weight Deflectometor (FWD) and the Seismic Pavement Analyzer. h was found that it may be difficult to directly compare moduli from laboratory and field tests. A methodology was proposed that can be used to combine these parameters in pavement design. The proposed methodology should be validated and modified using field tests. Results from accelerated pavement tests should be particularly valuable.
