Abstract
This report documents a preliminary investigation of Kentucky Rock Asphalt (Kyrock) - as a road surfacing material. The indigenous bituminous impregnated sandstone was widely used as a premium quality skid resistant surfacing material during the first half of this century. Redevelopment efforts gained momentum during the 1960's, but for the last twenty years interest has waned.
Laboratory tests were conducted on the Kyrock to determine its applicability in bituminous surface mixes by blending Kyrock with virgin materials in a similar manner as adding recycled asphalt pavement. The findings indicated it was feasible to blend Kyrock and a continuation proposal was presented.
