Field Trial of Solvent-Free Emulsion in Oregon

摘要

This final report summarizes construction, laboratory and performance information gathered by ODOT personnel from a single field trial of solvent-free emulsion mix constructed in June 2001. The solvent-free emulsion mix presented several placement problems as it built up on the laydown screed and gouged the mat. A second project trial section, scheduled for construction during 2001, was not completed due to construction scheduled problems. Following standard ODOT design policy, both the solvent-free and conventional emulsion mixes were overlaid with a chip seal shortly after placement. After fourteen months, the performance of both mixes appeared to be equal. The indirect tensile strengths of the two mixes were statistically similar at all ages up to one year.
