Résumé
An extensive study was conducted on a test section of asphalt pavement to produce needed temperature data from the desert portions of the Southwest. Solar radiation data were recorded concurrently for use in correlation with the temperature data. Typical temperature patterns for each month of the test period are presented and explained with the aid of heat transfer theory. Statistical analyses of the data show the average minimum and maximum temperatures throughout the test period as well as the temperature durations at various levels. Evaluation of the statistics has led the author to suggest possible modification of the present methods of testing asphaltic concrete in desert areas. Correlation between solar radiation and temperatures substantiates the theory that shallow depths are greatly influenced by the sun’s energy. Prediction of pavement temperatures is possible with the use of information from weather reports.

Mots clés : Pavements, Asphalt — Testing. ; Highway research.
