About this file
This document is an attachment to a request for bids (Solicitation # 61000 FD16 - Tioga Road) from the Pennsylvania Department of Conservation and Natural Resources (DCNR) for the supply of certified Driving Surface Aggregate (DSA) material. The approximate tonnage required is XX, which may increase or decrease based on the needs of the Department. The document outlines the specific physical and chemical properties required for the DSA material, including sieve size distribution, pH, LA Abrasion, and Plasticity Index. Contractors must either complete the DSA Contractor Acknowledgement form (A.1) or have a quarry complete the DSA Quarry Letter of Intent (A.2) to confirm their ability to supply the required DSA material. Failure to provide the appropriate completed form could result in the contractor being deemed non-responsive and disqualified.
The document provides details on the acceptable composition and properties of the DSA material, including allowing for the addition of lime kiln dust or cement kiln dust up to 50% of the fines passing the #200 sieve. The optimum moisture content for the delivered material is also specified. The successful contractor will be required to provide the DSA material at the specified quantities and quality for the duration of the contract.

Signed Acknowledgement of DCNR DSA Specifications
1. The Contractor must choose the appropriate acknowledgement letter:
| a. | DSA Contractor Acknowledgement of DSA Specifications (A.1) |
| This form is used when the Contractor will be creating and | |
| supplying the DSA. |
| b. | DSA Quarry Letter of Intent (A.2) |
| This form is used when the DSA will be created and supplied | |
| by a quarry not owned by the Contractor. |
| 2. | The appropriate form must be printed, completed in its entirety, signed, |
| and dated. |
| a. | Both A.1 and A.2 must be signed only by approved representatives |

4. Failure to comply with this requirement could result in a non-responsive determination and subsequent disqualification for the Contractor.
CONTRACTOR ACKNOWLEDGEMENT OF DSA PRODUCT
Solicitation # 61000 FD16 - Tioga Road Approximate Tonnage – XX (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.
