EFFECT OF UT TIME-TEMPERATURE MODEL ON DURATION OF ASPHALTIC CONCRETE CONSTRUCTION SEASON. EXECUTIVE SUMMARY
Weather conditions in Ohio were studied at four sites for which hourly records were available for a significant number of years. Air temperatures and wind velocities were analyzed during the months of March, April, May, October and November, together with other weather data. Application of a previously developed thermodynamic model resulted in a set of "limiting curves" of wind velocity vs air temperature which define permissible combinations of those variables for construction of bituminous mats of given thickness, for given base surface temperature. The criterion of acceptability was an average mat temperature of at least 175F, ten minutes after placement. Solar flux was found to have little influence during the first ten minutes and this parameter was assigned a constant value representative of Ohio during the months in question.
