ALTERNATIVE REFLECTION CRACK TREATMENTS PULVERIZATION AND RUBBERIZED SLURRY SRI

Nearly five miles of Interstate pavement near the northern Vermont border was rehabilitated during the summer of 1974, using two entirely different methods. A section of approximately two miles was pulverized and compacted and the remainder treated with a strain relieving interlayer of rubberized slurry prior to placement of a two-inch overlay over the entire project. These treatments were required to prevent the reflection of cracks through the new pavement. The two systems were chosen partly as an experimental program and partly due to the varying degree of distress of the pavement. Both were quite similar in cost, with the short-range benefits nearly equal. However, the pulverization process took a great deal longer than the rubberized slurry application. The performance of the two treatments will be evaluated during the next two winter seasons.
