For the past three years the Bituminous Section of the Virginia Highway Research Council has been working toward minimizing reflection cracking of both rigid and flexible pavements. For the last two years, the section's efforts have been focused on flexible pavements and the Pavement Section has concentrated on rigid pavements and transverse cracks resulting from cement treated bases. The materials used in the experimental work done so far polypropylene fabric, glass fabric, nylon, and latex all offer tremendous potential of extending the life of asphalt overlays for several years. However, the results of these experimental applications are still inconclusive because of the relatively short time they have been down. This year two new materials were added to those used in the past and new techniques in applications were also tried.
