CITY INVESTIGATES DIFFERENT ROADWAY REPAIR METHODS

Although total reconstruction was the best engineering solution for a long lasting road, this option was dismissed because of economic constraints and the fact that significant portions of the roadway had already been patched. Also ruled out was the use of a simple, thin asphalt overlay, which would eventually show extensive reflective cracking and allow water to seep through the pavement, again promoting deterioration. Using a non-woven engineering fabric in conjunction with a tack-coat application and a thin asphalt overlay is an accepted approach to solving crack retardation problems and appeared to be a viable solution. However, while exploring this method further, the Maryland State Highway Administration's Northern Regional Laboratory informed that a new method of fiber-reinforced pavement existed. The process uses short polymer fibers and is an offshoot of the now-banned asbestos reinforcement, and rubber-reinforced asphalt paving techniques.
