Experimental Paved Shoulders on Frost Susceptible Soils
Four paved-shoulder types were included experimentally in a construction project that also included continuously reinforced concrete pavement. The shoulder types were a bituminous-aggregate mixture (BAM) that served as both base and wearing surface; a cement-aggregate mixture (CAM) and a pozzolan-aggregate mixture (PAM) surfaced with bituminous concrete; and paving grade portland cement concrete (PCC). The BAM, CAM, and PAM mixtures also were used as pavement subbase. The construction took place in an area of frost-susceptible fine-grained soils that had been associated previously in Illinois with severe winter heave of the CAM and PAM shoulder types and concurrent freeze-thaw disintegration and structural failure. Durability improvements were made in the new CAM and PAM mixtures. (Modified author abstract)
