Abstract:

Fluctuation in temperatures significantly affects pavement stability and the selection of asphalt grading to be used in pavements. Ability to accurately predict the asphalt pavement temperature at different depths and horizontal locations based on ambient air temperatures helps pavement engineers in performing back-calculations of pavement modulus values. In addition, it helps engineers in selecting the asphalt grade to be used in various pavement lifts. The top pavement layer normally is exposed to greater temperature fluctuations than the layers below it. Knowledge of the temperature distribution in asphalts allows for a more sophisticated specification of asphalt for lower lifts (through specification of less expensive asphalt binders in lower lifts) and thus provides an economical solution to rising pavement construction costs. The study also examinations of the variability of predicted pavement temperatures on various pavement materials such as dense and open-graded asphalt mixes. 91 p.
