About this file
This document is an Attachment A from the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of Administrative Services related to a Driving Surface Aggregate (DSA) solicitation. The solicitation (#6100063922) is for the Tioga DSA Colton Road project with an approximate tonnage of 400, which can increase or decrease based on departmental needs. The document outlines detailed technical specifications for DSA and requires bidders to submit either a Contractor Acknowledgement of DSA Specifications (A.1) or a Quarry Letter of Intent (A.2) form with their bid response.
The technical specifications for the DSA include precise sieve size requirements, with specific passive sieve percentages ranging from 1-inch to #200 sieve, and additional technical parameters such as pH range (6-12.45), Los Angeles Abrasion loss (<45%), Plasticity Index (≤4), and optimum moisture content guidelines. Notably, the specifications mandate that fine materials passing the #200 sieve must be rock material, with no clay or silt soil permitted, and allow for limestone and sandstone aggregate material to be used to adjust aggregate distribution. Failure to comply with the submission requirements could result in a non-responsive bid determination and potential disqualification.

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 |
| with their bid response (either A.1 or A.2.). |
DO NOT attach both acknowledgements.
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 # 6100063922 FD16 - Tioga DSA Colton Road Approximate Tonnage – 400 (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. 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 11-17%.
pH: 6 – 12.45 as measured by EPA 9045C LA Abrasion: < 45% 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.
