Quarter Inch Specification
Purpose:
To develop a Seal Coat Specification that will allow the use of locally produced 1/4 inch (Rice) sized aggregates. The use of this material provides a smoother and less noisy ride on low volume > 500 ADT roads.
Local Government agencies have approached PennDOT to test and monitor numerous projects to obtain the information needed to add this product to the specification to the PUB 447 ( Approved Products for Lower Volume Local Roads) so they may pay for this treatment using their Liquid Fuels Monies.
Maintenance - Project No: ECMS E03718 WO 1
Anticipated Outcomes
- Suggest a range of aggregate sizes than can be obtained in Pennsylvania for use in Seal Coats.
- Throughly review and monitor the placement of this aggregate in actual field conditions.
- Gain approval of this product by the seal coat and aggregate industry.
- Implement this specification in the PUB 447 and reach out to municipal governments with information and education on its proper use.
