In an effort to study the prevention of reflective cracking of a thin overlay, an experimental overlay project was built and studied. Details are given of the control and test sections. Close-up color photos of the travel lane were divided into a fixed number of trapezoidal areas and each area was examined for a crack. Yearly surveys were conducted. Good crack prevention was achieved with heater scarifying with reclamite, heater scarifying with petroset, petromat, fiberglass, 200-300 LA Basin, ground tire rubber under ACFC, reclamite as flush on old AC, 120-150 per Four Corners asphalt, and 120-150 per LA Basin. Those giving 'fair' and 'poor' prevention capabilities are also listed.
