Field Evaluation of Warm-Mix Asphalt Technologies

摘要: AbstractWarm mix asphalt (WMA) has received considerable attention in the past few years to reduce energy consumption and pollutant emissions during hot (HMA) production placement. However, many concerns questions are still unanswered regarding field performance environmental benefits of WMA. In this study, WMA mixtures containing reclaimed pavement (RAP) were evaluated a project Ohio. The included using Aspha-min, Sasobit, Evotherm three test sections. Furthermore, control section was also produced so that side-by-side comparison could be made between HMA mixtures. Temperature monitored placement considered addition, core samples obtained from sections tested laboratory. Roughness rutting measurements conducted first 46 months service. results study showed signif...
