About this file
This is a specification acknowledgement attachment from the Pennsylvania Department of Conservation and Natural Resources (DCNR) for the delivery, placement, and compaction of approximately 1,300 tons of limestone Driving Surface Aggregate (DSA) to Blankley Road in Bedford County at Buchanan State Forest. The solicitation number is 6100065502 for project FD02. Contractors must submit either Form A.1 (Contractor Acknowledgement of DSA Product) if they will create and supply the DSA themselves, or Form A.2 (Quarry Acknowledgement of DSA Product—Letter of Intent) if a quarry not owned by the contractor will supply the material. Both forms must be printed, completed in their entirety, signed, and dated by approved representatives knowledgeable of DSA specifications. Only one form should be attached to the bid response; failure to comply with this requirement may result in non-responsive determination and disqualification.
The DSA must meet strict specifications including sieve analysis requirements (1-inch at 100%, ½-inch between 65-97%, #4 between 30-65%, #16 between 15-32%, and #200 between 11-15%), pH levels between 6 and 12.45 as measured by EPA 9045C, LA Abrasion loss of less than 45% per AASHTO T-96, Plasticity Index of 4 or less per ASTM D4318, and optimum moisture content delivery at plus or minus 1% as determined by Proctor Test ASTM D698 procedure C. All fines passing the #200 sieve must be rock material with no clay or silt soil permitted; limestone and sandstone materials may be used interchangeably for fines provided they meet specifications. The estimated tonnage of 1,300 tons may increase or decrease based on the department's needs.

Solicitation # 6100065502 FD02 - Buchanan Blankley Road Approximate Tonnage – 1,300 (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% 32%
#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 +/- 1% of that value, as determined for that particular source. The optimum percentage moisture will be determined using Proctor Test ASTM D698, procedure C, Standard.
