About this file
This document is an Attachment A for a Pennsylvania Department of Conservation and Natural Resources (DCNR) solicitation for Driving Surface Aggregate (DSA) for the Moshannon region, specifically for Little Medix and Jack Dent Roads. The solicitation number is 6100063794, with an estimated tonnage of 3,928 (subject to increase or decrease based on departmental needs). The attachment provides detailed specifications for contractors or quarries supplying DSA, requiring them to complete either Form A.1 (Contractor Acknowledgement) or Form A.2 (Quarry Letter of Intent), but not both. Contractors must demonstrate the ability to create and supply DSA that meets specific gradation, material composition, and performance requirements.
The DSA specifications include precise sieve size percentages, with requirements such as 100% passing 1½ inch sieve, 65-97% passing ¾ inch sieve, and specific guidelines for material composition. Technical specifications mandate a pH between 6-12.45, Los Angeles Abrasion loss less than 45%, and a Plasticity Index of ≤4. The document emphasizes that fines passing the #200 sieve must be rock material, with no clay or silt soil allowed. Limestone and sandstone aggregate can be mixed to meet distribution requirements. The material must be delivered at optimum moisture content, determined using the Proctor Test ASTM D698. Failure to comply with these specifications 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
(FORM MUST BE COMPLETED BY BIDDING CONTRACTOR)
Solicitation # 6100063794 FD09 - Moshannon Little Medix and Jack Dent Roads Approximate Tonnage – 3928 (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.
Passive Sieve
Low Percentage
High Percentage
1 ½ inch 100% -- ¾ inch 65% 97%
#4 30% 65% #16 15% 30%
#200* 11% 15%
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.
