UNIVERSITY OF TOLEDO TIME-TEMPERATURE MODEL LABORATORY AND FIELD VALIDATION

This report validates the use of The University of Toledo Time-Temperature model to predict the temperature of a cooling layer of freshly placed hot asphalt concrete. Both laboratory and field tests were conducted to demonstrate that the model predicts the average temperature from the time the asphalt concrete layer is placed until 20 minutes after placement. To use the model, it is necessary to know the thermophysical properties of asphalt concrete. These properties for the materials used in the State of Ohio were measured and are reported. The appendices include HP-97 programs which can be used to implement the predicting model. (FHWA)
