Appendix a Correlation of Construction Quality Criteria with Performance of Asphaltic Concrete Pavements

This report is concerned with the determination of relationship between asphaltic concrete surface course specifications and the level of performance of pavements constructed under these specifications. The relationship was investigated through comparative evaluation of deficient (in specification) and nondeficient sections using a combination of pavement condition rating and ride rating as the criteria for evaluation. The analysis and evaluation of the data indicated (1) a recognizable difference in the level of performance for the 100 percent pay or non-deficient sections and the deficient sections for stability and surface tolerance criteria of acceptance; (2) little difference in the performance level between the two groups of sections for compaction criteria deficiency; (3) pot hole patching for test or deficient sections to be much more than the corresponding control or nondeficient section (4) that majority of the sections (control or test) have not reached end of life according to PSI measure of serviceability.
