The State Conservation Commission and the Department of Transportation announced that Driving Surface Aggregate is now approved for Liquid Fuel Tax Funds expenditure to rebuild local roads.

The specification for this item listed as MS-0450-0004 can found in the Bureau of Municipal Service’s Publication 447 (Approved Products for Lower Volume Local Roads).

Driving Surface Aggregate or DSA is a mixture of crushed stone developed specifically as a surface wearing course for unpaved roads. DSA has a unique particle size gradation designed to maximize packing density and produce a durable road surface that performs better than conventional aggregates.

PennDOT’s New Products Evaluation Program for Lower Volume Local Roads is in place through a research project that promotes collaboration with transportation partners and technical advisors to approve products that may be paid for with Liquid Fuels Funds.

DSA was developed under a project by Dirt and Gravel Road Maintenance Program that provides financial incentives for local officials to implement techniques that prevent pollution that can impact state waterways.

Environmentally sensitive maintenance practices have been developed to provide maintenance techniques for unpaved roadways that have been identified as sources of dust and sediment pollution.
