Abstract:

Accumulating evidence that inadequate subsurface drainage of some pavements was related to impervious base courses led to an investigation of the influence of low permeability fine materials on the physical characteristics of typical base courses. It was determined that a reduction in the minus 200 fraction of typical base courses from an average of 10% to an average of 7% was accompanied by a 1,000- to 10,000-fold increase in permeability with no adverse effects on California Beaming Ratio values or on maximum dry densities. These findings led to the development of a suggested revised gradation design mange calling for from 8% to 8% minus 200 material as opposed to the old mange of 8% to 12%.
