... Most of the studies involved the comparison of specific pavement preservation and maintenance treatments, such as chip sealing or microsurfacing, to hot mix or portland cement concrete overlays or rehabilitation. Although this information is valuable, there is no single source of environmental sustainability data on the suite of commonly used pavement preservation and maintenance treatments.
