Statement of Work: Provide a technical and cost proposal to Mill and Overlay the USDA ARS Cotton Gin Laboratory parking area and existing asphalt paved lot with Hot Mix Asphalt at 111 Experiment Station Road in Stoneville, MS.

Project Objective: The objective of this project is to perform base repair as required, mill 1.5” of existing asphalt over entire parking area and existing asphalt paved lot, overlay the milled surface with Hot Mix Asphalt, seal minor, irregular areas with approved coal tar sealant, and restore all pavement markings and traffic loops.

Contractor must be registered in System for Award Management, (SAM), prior to submitting a bid. Registration can be obtained through:

https://www.sam.gov

Site Visit: Bidders are encouraged to visit the site and be escorted by a government representative to confirm locations, dimensions, and conditions of the project before a bid is submitted. The site visit shall be for the purpose of observing firsthand any conditions relevant to the completion of this project. No consideration will be given to claims based on lack of knowledge of existing conditions, except where contract documents make definite provisions for adjustment in cost or extension due to existing conditions not readily foreseeable. This project is located at USDA-ARS Cotton Gin Research campus at 111 Experiment Station Rd. in Stoneville, MS.

Utilization of Bio-Based Products: The contractor shall make every effort to utilize products and material based from bio-based materials, (e.g. bio-based greases; bio-based hydraulic fluids, bio-based absorbents), to the maximum extent possible without jeopardizing the intended end use or detracting from the overall quality delivered to the end user. All supplies and materials shall be of a type and quality that conform to the applicable Federal Specifications and Standards. All supplies and materials to be used in the performance of work described herein are subject to the approval of the Contracting Officer Representative (COR). Products can be found at:

https://www.biopreferred.gov

Safety: The contractor will submit a Site Safety Specific Plan/Accident Prevention Plan in industry recognizable format to the Contracting Officer within 14 days of contract award. The Plan shall include phone numbers and maps to the local Dr. Office and nearest Hospital.

Base Bid: Provide all equipment, labor, and materials necessary to:

Perform base repair(removal and backfill approximately 300 SY) on structurally failed asphalt, Mill and overlay asphalt parking lot (12,000 SY), Seal irregular and inaccessible areas with approved coal tar based sealant (approximately 1000 SY), Replace pavement markings, and replace traffic detector loops for gate access system.

Background – The current parking area and gin lot for the USDA ARS Stoneville Cotton Ginning Research Facility has been paved and/or microsealed a number of times through the years such that the average depth of existing structure is approximately 6” throughout the facility. The entire existing asphalt paved surface is exhibiting reflective cracking and block cracking to various degrees on most of the area as well as alligator cracking on approximately 300 SY of failed asphalt. Cores in this failed area showed severe stripping along with a saturated clay basement soils. This area needs the pavement to be removed and the clay to be excavated to a depth of 1’, backfilled with crushed 610 limestone compacted and paved to match existing grades before milling begins. Various crack sealing has been performed extensively and was topped with a coal tar based sealant. It is desired to mill and fill 1.5” of asphalt, all areas that are accessible to milling and paving machines, and seal the remaining irregular and inaccessible areas with an approved coal tar based sealant. Milling and paving operations should be coordinated such that the milled surface is covered within 4 weeks or less. The existing pavement houses detector loops for the gate controls and these loops will need to be replaced after asphalt placement. Likewise, existing pavement markings need to be replaced after paving and sealing are finished.

Task List:

• Sawcut existing asphalt pavement (approximately 6” in depth) around failed area (approx. 200 LF)

• Remove failed asphalt (approx. 300 SY)

• Excavate failed area basement soils to a depth of 1’ to establish a stable foundation for base repair

• Backfill failed area with a dense graded crushed limestone (610 gradation or approved equal) to a depth of

1’ and compact to a density of 95% standard proctor. All rolling to be done is static mode.

• Backfill repaired area with approximately 6” of 19mm Hot Mix Asphalt to match adjacent structure thickness and achieve a density of 92%. All rolling to be done in static mode.

• Perform cold milling to a target depth of 1.5” on entire paved parking area and gin lot where accessible to milling and paving equipment (approximately 12,000 SY).

• Apply trackless tack coat at a rate of 0.06 gal/SY to all milled surfaces

• Overlay milled and prepared surface with 9.5mm Hot Mix Asphalt and compact to a density of 92-95%. All rolling to be done in static mode.

• Apply Coal Tar based sealant on all old, irregular, and inaccessible asphalt surfaces that could not be reached with milling and paving.

• Replace all existing pavement markings to include stipe and handicapped legend

• Replace traffic detection loops for gate operation.
