The temperature at which compaction takes place is an important factor in the construction of asphalt concrete pavements. In cold climates, rapidly cooling mats can contribute to poor compaction. Under warm paving and high traffic demand conditions, time of construction is a greater concern, and the compaction schedule should minimize the required time for construction. This research created a computer tool (CalCool), based on theoretical heat transfer considerations, for use by pavement designers and on-site construction crews to predict the pavement temperature during construction and modify designs or compaction procedures accordingly. A model validation study compared CalCool to several construction scenarios. The comparisons were favorable in the single-layer cases, but increased discrepancies were observed Fin the multi-layer cases. Future validation studies are needed to expand the data set beyond the two sites examined in this paper. |
