Abstract

The main aim of this paper is to analyse the performance of different intelligent compaction measurement values (ICMVs) and compare them with spot test measurements for asphalt pavement. To accomplish this, a two-layer asphalt testbed was constructed using an instrumented double-drum roller. All ICMVs [compaction meter value ((Formula presented.)), compaction control value ((Formula presented.)), roller-integrated stiffness ((Formula presented.)), and vibratory modulus ((Formula presented.))] were calculated using the same accelerometer data collected during the construction of the asphalt testbed. The analysis of ICMV data showed a strong correlation between (Formula presented.) and (Formula presented.), while (Formula presented.) and (Formula presented.) demonstrated a strong correlation only when double jump of the roller drum did not occur. Further, none of the ICMVs recorded during the last roller pass of asphalt compaction showed an acceptable correlation with asphalt densities [measured using a non-nuclear density gauge (NNDG)], mainly due to the influences of the underlying support and asphalt temperature on ICMVs. A correction method to decouple the influence of underlying support on (Formula presented.) was developed and validated using existing data from the literature. The applicability of this method for different field scenarios was demonstrated using numerical modelling.
