Lean Mix Concrete Base Widening
An experiment was established in Illinois in 1951 on a typical widening and resurfacing project to determine whether portland cement concrete widening strips with cement contents lower than that considered standard for regular paving concrete would serve adequately under dense-graded bituminous concrete resurfacings. Cement factors of 1.31, 1.19, and 1.07 were used in addition to the Illinois standard of 1.42 for pavement concrete constructed with the aggregates used on this project. Condition surveys were made periodically during the 14 years in which the pavement served before a second resurfacing was placed for differences in pavement performance attributable to variations in the cement contents of the widening strips. This evidence was concluded to suggest that cement contents can be reduced where environmental conditions are no more severe than those to which the experimental site was exposed. (Author)
