About this file
This document is the Attachment A for the DCNR DSA (Driving Surface Aggregate) Specifications related to a state contract opportunity. It outlines the requirements for the Contractor or Quarry to acknowledge and confirm their ability to competently create and supply certified DSA that meets the specified sieve, pH, LA Abrasion, and Plasticity Index requirements for two project solicitations - Rothrock Laurel Run Road (Approximate Tonnage 1800) and Michaux Laurel Run Road (Approximate Tonnage 1800). The Contractor or Quarry must print, complete, sign, and date the appropriate acknowledgement form (Contractor or Quarry) and include it with their bid response. Failure to comply could result in the bid being deemed non-responsive and the Contractor being disqualified.
The document provides detailed technical specifications for the DSA, including sieve size percentages, pH range, LA Abrasion limit, and Plasticity Index. It also specifies that the fines passing the #200 sieve must be rock material with no clay or silt soil, and that lime kiln dust and cement kiln dust may be added to account for up to 50% of the fines. The material must be delivered at the optimum moisture content or up to 2% below, as determined by ASTM D698 Proctor testing.

ATTACHMENT A
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 |
| of the Contractor and Quarry respectively. |
b. The authorized representative must include their title with their signature.
| c. | Representatives must be knowledgeable of DSA and be prepared |
| to answer all questions on the product. |
| 3. | The Contractor must then include the appropriate fully executed form |

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 # 61000000000 FD05 - Rothrock Laurel Run Road Approximate Tonnage – 1800 (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.
