| dc.description.abstract | Warm mix asphalt (WMA) is increasingly being tried in highway paving in the United States. Apart from environmental benefits, WMA is being considered useful in projects involving long haul distances and late season paving operations due to its material characteristics and the rate of cooling during field compaction. This thesis investigates whether WMA cools at a slower rate than hot mix asphalt (HMA) to offer more compaction time. Following an indirect investigative approach, comparative analysis of field observations with software predicted values for two paving projects was carried out. The results indicated that some types of WMA cool at a slower rate than HMA and would allow a longer period of compaction time to achieve the same density as HMA. The findings presented here can be informative to the asphalt paving industry in considering WMA for use in long haul, nighttime, and late season paving. | en_US |
