PERMEABILITIES AND LOAD SUPPORT CHARACTERISTICS OF MATERIALS USED AS BASE OR SUBBASE COURSES IN NEW JERSEY HIGHWAYS

This report describes an investigation of the drainage and load carrying characteristics of natural, bank-run soils, and quarry processed materials, which are used as base and subbase layers in the current design sections of New Jersey highways. These characteristics are evaluated in light of the design assumptions held by the Department regarding th subject materials. They are further evaluated in the context of the constraints and/or requirements placed upon them by the highway "environment" and loadings. Insight regarding the effects of "blending" (the addition of coarse, crushed aggregate to bank-run soil) is provided, along with commentary on future availability of materials. Finally, some analysis and discussion of theoretical permeeability prediction methods is presented. /FHWA/
