Here’s yet another example of how Integrated Paving Solutions can save time and money in paving. In this case, the Hopkins High School in Hopkins, Ma., used full-depth reclamation (FDR) to replace a deteriorating asphalt road with cement.

The half-mile look asphalt road is heavily used by school buses and needed a replacement material that would make the road more durable to bus traffic and to reduce the cost. The Garrity Paving Company completed the work. The first day consisted of the pulverization of the old pavement. During the next morning, in approximately four hours, the entire FDR process was completed. The cement spreader was provided Cement Quebec and Essroc Cement provided the cement.

With FDR, the full thickness of the asphalt pavement and a pre-determined portion of the underlying materials are uniformly pulverized and blended to provide an upgraded homogeneous base material. Cement is blended into the soil and recycled asphalt to provide a stronger base for future asphalt or concrete paving. FDR has been estimated to be about 50 percent less expensive than traditional full-depth repair.

An FDR demo was conducted in Hopkinton last month and about 40 people attended, including representatives from the Massachusetts DOT, state and local governments.
