When residents in the vicinity of Bradley Road brought the attention of dust clouds being generated by traffic speeding through the last gravel road in the Township, the staff under the direction of Manager Barry Luber sought the most cost-effective way to reduce, if not eliminate the problem. The Township reduced the speed limit and Warrington Police Chief Dan Friel ordered extra police patrols on the roadway however, that did not resolve the issue. The road, which dates back to the 1800’s has poor drainage and is marshy ground and to rebuild it to today’s standards would be extremely expensive. Since it is used by emergency service vehicles, closing Bradley Road was not a viable option.
The solution that the Township Engineer, Tom Zarko, P.E. CKS Engineers, came up with was a relatively simple one. Penn State University had been developing a specific type of material for use on gravel roadways that would be long-lasting and not crumble and generate dust problems. The product is Driving Surface Aggregate, or DSA as it is commonly known. It had proven effective in Central Pennsylvania where there were miles of gravel roadways, but never applied in the Eastern part of the State. After a great deal of effort a quarry in Easton was found that would agree to manufacture this material. The Township’s Public Works Department under the leadership of Joseph Knox will grade the road and make some drainage improvements and then the contractor, A. H. Cornell & Son Inc. will apply the DSA to the road. This will eliminate the dust. In addition, a barrier of flexible delineators will be installed by Public Works that, combined with the reduced speed limit, should slow the traffic down.
This project is being funded by a grant from the Bucks County Conservation District (BCCD).
In summary, the combination of new technology, cooperation with Penn State University and BCCD and the use of local forces generated a low-cost solution to a major problem.
This project is slated to begin during the first week of September.
