Evotherm Warm Mix Asphalt Technology Applied on Ultra-Thin Pavement in China
With the characteristics of Evotherm warm mix asphalt technology introduced, the existing problem about hot mix asphalt technology applied on ultra-thin pavement was put forward. The research on the workability of Evotherm warm asphalt mixture was conducted by measuring the Brookfield dynamic viscosity of Evotherm warm mix asphalt and hot mix asphalt (HMA) at different temperatures, which can guide the mixing and compaction temperature range. Based on test results of laboratory performance, the warm mix asphalt ultra-thin pavement was paved in China at low air temperature. The temperature vs. time curve of Evotherm warm asphalt mixture was derived theoretically by Pavecool® software in advance. The field temperature vs. time curve was also obtained by field test result of Evotherm trial road, which can guide the compaction occasion of the Evotherm warm mixture. The pavement performance of trial road was positive, which demonstrated that the application of Evotherm warm mix asphalt on ultra-thin pavement was successful at low air temperature in China.
