Asphalt Concrete Overlays of Flexible Pavements. Volume 1. Development of New Design Criteria
Fatigue and rutting criteria were developed and incorporated into a design procedure for flexible overlays of flexible pavements. The AASHO Road Test flexible pavement sections were used as a data base. Field studies were conducted to obtain data and materials were sampled and tested to determine modulus of elasticity values. The fatigue criteria developed in this report is based on observations of distress on in-service pavements along with mechanistic analyses using elastic layered theory to predict strains in the asphalt concrete. The traffic prior to the beginning of Class 2 cracking was combined with the strains to develop a regression model for fatigue. Rut depths, traffic, stresses, and strains were combined to develop a regression model for rutting. Consideration was given to the relation of rutting to temperature. The stresses and strains were predicted using elastic layered theory. A summary of the overlay design procedure is presented as well as a comparison with existing procedures. This volume is the first in a series. The other in the series is: Vol. 2. FHWA-RD-75-76 Asphalt Concrete Overlays of Flexible Pavements - Design Procedures.
