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.
