It was found (from full-scale accelerated traffic tests conducted by the U.S. Army Corps of Engineers), that for similar pavements, the relationships between observed failure coverages for different loads and gear assemblies provided a better correlation for flexible pavements than for rigid pavements. The test track results show that there may be variables in tests, which could adversely affect either the performance, more in rigid pavements than in flexible, pavements or only the performance of rigid pavements. Conclusions drawn from the study are presented and relate to the following: joints; crack patterns and stress distribution; inconsitencies resulting from joint systems in rigid pavements; and temperature and moisture differentials and the warping and breakage caused by them.
