About this file
This is a specifications and acknowledgement document for a state contract opportunity issued by the Commonwealth of Pennsylvania, Department of Conservation and Natural Resources (DCNR), Tioga Forest District, for Solicitation #6100065142 FD16 - Tioga Strait Run Road. The project requires the delivery, paver-placement, and compaction of approximately 3,750 tons of limestone Driving Surface Aggregate (DSA), with tonnage subject to adjustment based on departmental needs. Contractors must acknowledge their ability to competently create and supply certified 4" MINUS aggregate meeting specified standards and must submit the appropriate acknowledgement form (either Form A.1 or A.2) as part of their bid response. Failure to comply with the acknowledgement requirement will result in a non-responsive determination and disqualification.
The 4" MINUS aggregate specifications require compliance with Section 9106 of the PA Vehicle Code, mandating that all material be derived from natural stone formations and crushed rock. Material must meet specific sieve gradations (ranging from 4-inch down to 1/2-inch), pH levels of 6-12.45, LA Abrasion less than 40% loss per AASHTO T-96, Plasticity Index of 4 or less per ASTM D4318, and optimum moisture content between 4-6% per AASHTO T255. Contractors may either submit Form A.1 (if they will create and supply the aggregate directly) or Form A.2, a Letter of Intent from a supplying quarry not owned by the contractor. All acknowledgement forms must be signed and dated by authorized representatives who are knowledgeable of the 4" MINUS product and include the representative's title; only one form should be submitted with the bid.
