PaveCool has been developed to assist contractors, inspectors and engineers to make rapid decisions regarding cool-weather paving. A heat flow model is used to compute the temperature drop in the mat and the time it takes for the asphalt mix to cool from it’s delivery temperature to the minimum compaction temperature. If the user feels that there is an inadequate amount of time available to compact the mixture, options can be explored to extend the time. For instance, increasing the lift thickness or mix temperature will increase the window of time for effective compaction of the pavement.
Bruce Tanquist is the Pavement Computer Applications Engineer at the Minnesota Department of Transportation, where he has created PaveCool.
