The prevalence of reflective cracking in asphaltic concrete overlays is a major factor contributing to the premature failure in the pavement system. This reflective cracking is caused by cyclic stresses induced in the overlay by movements in the underlying pavement. Recent work done with heavy duty membranes has shown that they may be useful in retarding this reflective crack formation. Seven different types of heavy duty membranes were placed over portland cement concrete pavement joints at a site in Pennsylvania before the roadway was overlayed with asphaltic concrete. Control sections, without any membranes, were also built into the project for comparison purposes. This work will evaluate the ability of these membranes to reduce the occurrence of reflective cracking over transverse and longitudinal joints and to function as a water stop once cracking has occurred.

This compendium gathers the latest advances in the area of Accelerated Pavement Testing (APT), a means of testing full-scale pavement construction in an accelerated manner for structural deterioration in a very short term. Compiling novel research results presented at the 5th International Conference on Accelerated Pavement Testing, San Jose, Costa Rica, the volume serves as a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of a pavement structure during its service life (10+ years) in a few weeks or months.
Geosynthetics for Reflective Crack Control

Reflective cracking due to shrinkage and brittleness in asphalt pavements can seriously degrade an asphalt overlay before it is near its design life. Geosynthetics have been used to impede the reflection of existing transverse cracking to the new overlay. The geosynthetics are intended to minimize the tension transferred to the overlay from the existing pavement. The Oregon Department of Transportation (ODOT) installed a test section consisting of 120 transverse cracks treated with five different geosynthetic types, 22 transverse cracks treated with crack filling only and a control section of 20 untreated transverse cracks. The test and control sections were constructed over an open-graded asphalt concrete pavement. The overlay was also an open-graded mix. The 140 transverse crack section is located on US Highway 97 between Milepoint 213.58 and Milepoint 217.64.

Prevention or control of reflection cracks in asphaltic concrete overlays has been a problem from the inception of this type of construction. The many different treatments that have been tried in an effort to solve this problem are: (1) reinforcement within and below the overlay, (2) bond breakers, (3) stress-relieving layers, (4) asphalt-mix additives, and (5) placement of fabrics between the existing pavement and the overlay. At the present time, no treatment has been tried that will completely prevent the formation of reflection cracks. Some treatments do delay the formation of cracks, while others do not appear to help at all. Indications are that fabrics do have some beneficial effects, such as a moisture barrier, even though the overlays develop reflection cracks. The fabrics that have been tried for the control of reflection cracks included: (1) Petromat, (2) Bidim, (3) Typar, (4) Cerex, (5) Mirafi, (6) Structofors, (7) Bituthene, (8) Protecto-Wrap, and (9) Fiberglass. Asphalt-rubber interlayers, as formulated by the Arizona Refining Company and the Sahuaro Petroleum Company, show promise in retarding reflection cracks. (Author).
