This project will involve pit development of a government source, mining materials, crushing pit material into a blended surface course aggregate with commercial source additives.
Items to complete:
Crush and Stockpile Aggregate includes development and use of pits, either government source or commercial source, to the specified gradation, including adding approximately 2% bentonite by weight to achieve desired properties. Actual % will be based on contractor’s initial materials testing. This includes clearing and grubbing, removing overburden, mining, crushing, mixing aggregate with bentonite using a pugmill, weighing, creating stockpiles (including any loading or hauling to create stockpiles), testing, and final site reclamation including placing overburden, waste materials, mulching, and seeding. Perform the work in accordance with MSHA 30 CFR, part 56.
Surfacing - Aggregate Surface Course includes necessary surface preparations before placing aggregate such as: material and quality control testing, surface preparation (reconditioning), clearing and grubbing, spreading, watering, compacting, temporary traffic control, erosion control measures, and all other incidental work to surface the road (see surfacing typical on sheet G-05).
Surface to the compacted depth specified in the drawings for the full roadway width, including all existing turnouts and widenings. Intersecting roads shall be bladed, shaped and surfaced for a smooth transition. Spread control and staking for aggregate is the responsibility of the contractor.
Protect the environment and resources impacted by all construction activity according to all legal requirements, regulations, specifications, and best management practices (BMPs).
East Leesburg Pit: Develop pit for operations, including clearing and grubbing, all incidental to crush and stockpile aggregate payment. Mine, crush, and blend aggregate with approved additives, stockpile material in the pit for surfacing.
