REFLECTION CRACKING OF BITUMINOUS OVERLAYS FOR AIRPORT PAVEMENTS; A STATE OF THE ART
This report surveys current methods and practices pursued by various pavement authorities in an effort to reduce the incidence of reflection cracking of bituminous overlays. The most common theoretical, analytical and laboratory efforts in this connection are also presented. Latest information concerning these measures and their successes, failures and uncertainties is stated from interviews with cognizant personnel in the field, and at universities and government research agencies. Other information is presented from construction records, site visits and published material. The findings in this research effort are that the state of the art in preventing reflection cracking of bituminous overlays, excluding afew institutional efforts, has not developed along systematic lines and, to date, there is no methodology by which the degree of effectiveness of any method in place can be predicted under a variety of conditions. Also, field experimentation has not yielded reproducible results partly because of lack of good experimental design and statistical methods, adequate quality control and documentation of all significant variables.
