About this file
This document is an attachment to a state contract opportunity issued by the Pennsylvania Department of Conservation and Natural Resources (DCNR) for Driving Surface Aggregate (DSA) for the Moshannon Benner Run Road project. The solicitation number is 6100054151 FD09, and the estimated quantity is 8,500 tons, though the actual quantity may increase or decrease based on the department's needs. The document outlines the technical specifications for the DSA, including requirements for particle size distribution, pH, LA abrasion, plasticity index, and optimum moisture content. Contractors must either complete the "DSA Contractor Acknowledgement of DSA Specifications" form or the "DSA Quarry Letter of Intent" form, depending on whether the contractor or a quarry will be supplying the DSA. These forms must be signed by an authorized representative and submitted with the bid response.
The document does not provide details on pricing terms, set-asides, incumbents, funding sources, or other commercial aspects of the contract. It focuses solely on the technical specifications and requirements for the DSA product.

CONTRACTOR ACKNOWLEDGEMENT OF DSA PRODUCT
Solicitation # 6100054151 FD09 - Moshannon Benner Run Road Approximate Tonnage – 8,500 (Tonnage is estimated and can increase or decrease based on the needs of the Department.)
By signing this acknowledgement I, _______________________________________ (Print Name), an authorized representative of ____________________________________________ (Name of Contractor), confirms that ___________________________________________ (Name of Contractor) has the ability to competently create and supply certified Driving Surface Aggregate (DSA) for the Solicitation listed above that meets the following specifications.

The fines passing the #200 sieve must be rock material. No clay or silt soil may be added. Limestone material passing the #200 sieve may be used to make up a deficit in the distribution of sandstone aggregate rock, and vice versa. All added material passing the #200 sieve must be derived from rock material that conforms to program specifications. Lime kiln dust and cement kiln dust may be added to DSA to account for up to 50% of the fines passing the #200 sieve. The amount of particles passing the #200 sieve will be determined using the washing procedures specified in PTM No. 100.
*If the Plasticity Index for the Material is 2 or below, then the #200 sieve is permitted to be 10-17%.
pH: 6 – 12.45 as measured by EPA 9045C LA Abrasion: < 40% loss based on Los Angeles Abrasion test, AASHTO T-96 [ASTM C 131] Plasticity Index: ≤ 4 based on ASTM D4318 – Standard Test Method for Liquid Limit, Plastic Limit, and Plasticity Index of Soils.
Optimum Moisture: Material will be delivered and placed at optimum moisture content, or up to 2% below that value, as determined for that particular source. The optimum percentage moisture will be determined using Proctor Test ASTM D698, procedure C, Standard.
