REFLECTIVE CRACKING CAN BE STOPPED

An overlay project to stop reflective cracking in a Jacksonville airport is described. Weathering cracks up to 2 inches, and the increasing use of a 30-yr-old pavement (consisting of 4 inches of mixed-in-place sand-asphalt topped by 2-inch overlay of asphalt concrete) prompted plans to upgrade the pavement. The plans consisted of the following phases: chemically removing plant growth from the craks; cleaning the pavement and eliminating wind-blown sand from the cracks; applying an asphalt-aggregate slurry seal to fill cracks; applying a surface treatment with coarse aggregate of 3/4-inch uniform size; and placing a hot-mix asphalt concrete course in 2 lifts totaling 3-1/2 inches in thickness.
