Missouri Field Trial of Warm Mix Asphalt Technologies: Construction Summary
Warm mix asphalt (WMA) mixtures produced using several different WMA technologies were evaluated in a field project located in St. Louis, MO. The technologies evaluated were Aspha-min zeolite, Sasobit, and Evotherm ET (emulsion technology). A control section was also produced so comparisons could be made between WMA and conventional Hot Mix Asphalt (HMA). Mixture volumetrics, rutting resistance, moisture susceptibility, and dynamic modulus were conducted to evaluate field performance. In-place field performance data was also collected. Laboratory tests indicated all three WMA technologies performed statistically equal or better than the control mixture, except for the dynamic modulus results for the Aspha-min, which resulted in significantly lower values. Field performance for all technologies has been good, with no rutting and minimal cracking after two years of heavy traffic.
