Minimizing Premature Cracking in Asphaltic Concrete Pavement.

摘要

The objectives of this research were: (1) to prepare a series of recommendations dealing with materials specifications,mix design,structural materials selection,and construction requirements that can be used by asphalt pavement designers to reduce the possibility of premature cracking in the pavement;and (2) to suggest procedures for verification of the recommendations. All available information from recent and current research and field experience was reviewed and evaluated. Recommendations were prepared for minimizing fatigue,low-temperature,and reflection cracking. It was determined that,because of the large number of variables,conventional experimental programs for field verification of the recommendations would be very costly and time consuming. An alternate procedure,using Bayesian analysis methodology,is suggested for verification of the recommendations for minimizing premature cracking.
