EFFECT OF BASECOURSE SATURATION ON PAVEMENT

Recent investiations have suggested that a high degree of base course saturation could be an important contributing factor to pavement failures. Research has shown that a degree of base course saturation of 80 percent is sufficient to create pore water pressure build up and associated loss of stability when a pavement is subjected to repetitive traffic loading. In this paper, factors associated with pore water pressure build up in partially saturated or saturated base courses are reviewed in general terms, and a theoretical and experimental research program aimed at obtaining a clearer understanding of the problem briefly outlined. The above research is being carried out by the University of Auckland as part of a major research project undertaken for the National Roads Board on base course and subgrade drainage design. /AUTHOR/
