WARM ASPHALT MIX TECHNOLOGY AN OVERVIEW OF THE

2.0 INTRODUCTION TO WARM MIX TECHNOLOGY . As originally discussed by Davidson, Tighe and Croteau [1], several new processes have been developed to reduce the mixing and compaction temperatures of hot mix asphalt. These processes are known as warm mix asphalt. The lower temperatures should result in lower plant emissions and lower fuel consumption.
