Title:

Roller-Integrated Compaction Monitoring for Hot Mix Asphalt Overlay Construction

Accession Number:

Abstract:

This paper documents recent experience using roller-integrated compaction monitoring (RICM) technology on hot mix asphalt (HMA) overlay construction projects in Iowa. Recently, new special provisions (SPs) to specifications were implemented by the Iowa Department of Transportation (DOT) on three projects which required the use of RICM technology for HMA compaction in the break down position. RICM data was collected and analyzed in conjunction with in situ falling weight deflectometer (FWD), nuclear density gauge, and surface temperature testing conducted on the project sites. Results from the field projects are analyzed to evaluate: (a) differences in roller compaction control value (CCV), relative compaction (RC), and surface temperature with increasing pass count, (b) statistical correlations between CCV, RC, and FWD modulus and factors influencing the correlations, (c) RICM pass coverage uniformity using univariate and spatial geo-statistical methods, and (d) evaluate RICM data coverage over each project area. The results, analysis, and experiences documented in this paper can be useful in developing future RICM specifications and QC/QA guidelines for HMA construction.
