dc.description.abstractThe AASHO Road test is the only comprehensive source of information on the relative damaging effect of different individual axle loadings. From the results of this test a detailed set of traffic equivalence factors was derived by Liddle under idealised conditions at a site where frost action was a significant factor causing pavement failure. The common approach now for road pavements is to reduce mixed traffic loadings to the single unit of equivalent standard axle loadings (ESAL). Which is the number of passages of a standard axle load that causes the same amount of damage as the mixed traffic. In !lie Road test any given pavement section was trafficked by wheel loads of a single magnitude. Relations between wheel load, being half the axle load and damaging power were obtained by comparing the number of repetitions of a load of a given magnitude required to cause structural failure of a pavement with the number of repetitions associated with another wheel load to bring the same failure condition. - The generally accepted interpretation of results yields the well known fourth power relation between magnitude of wheel load and its structural damaging power. A major contribution of the AASHO Road test was to quantify damage through, firstly, quantifying the subjective rating of the pavement condition in the present serviceability rating (PSR) and secondly by correlating the PSR to physical measures of distress defined as present serviceability index (PSI). The serviceability index was thus an explicit combination of various distress types,en_US
