Abstract:

WMA overlays were placed in several pilot projects in Connecticut during the 2010 and 2011 construction

seasons. These technologies included Sasobit®, Evotherm™, Advera®, Double-Barrel® Green foamed

asphalt as well as SonneWarmix™. The research team observed placement and collected mix for

laboratory testing. Laboratory testing consisted of rut testing and moisture susceptibility testing both with

the Hamburg wheel-track test and with tensile strength testing. One of the pilot projects included SBS

polymer modified asphalt binder. While the WMA mixes containing the polymer seemed to outperform the

others overall in the laboratory, all of the WMA mixes appeared to perform satisfactorily in the laboratory.

Temperature reductions were observed in the field. With the exception of a couple compaction related

problems in the field (not believed to be caused by WMA technology) all mixes appeared to perform

satisfactorily during placement. Upon revisit to the sites during 2013, all sections were still performing well.

The research team recommends further monitoring of these sections during the coming years.
