Statement of Work (SOW) Pavement Preservation at Kincaid Campground Loops

Calcasieu Ranger District Kisatchie National Forest

June 2018

Existing Conditions

1. The asphalt road system comprising the “Big Loop” and the “Little Loop” in the Recreational Vehicle camping area at Kincaid Lake Recreation Area is beginning to fail under the heavy use and ever heavier vehicles.

2. Potholes, surface cracking, and wagon tracking are common conditions of the campground loop.

General.

The project involves:

Pothole patching and asphalt overlay.

1. The contractor shall supply all material, labor, tools, equipment, vehicles, supplies, incidentals, supervision and safety measures to complete the project.

2. The contractor shall work to maintain the safety of the public in all operations.

3. Surface preparation. Clean the existing surface of loose material, dirt, or other deleterious material by approved methods as follows: Apply an asphalt tack coat to contact surfaces of pavements, curbs, gutters, manholes, and other structures according to Section 412, FP-14.

4. Weather Limitations. Place asphalt concrete mix on a dry, unfrozen surface when the air temperature in the shade is above 35 °F (1.7 °C) and rising. For HMA, conform to Table 401-2. For 2” lifts, minimum lay down temperatures should be as follows:

COMPACTED LIFT THICKNESS---> < 2 INCHES 2 -3 INCHES > 3 INCHES

Products.

1. Government furnished products: NONE

2. Contractor furnished products: ALL, In Accordance With section 400 of FP-14.

a. Submit written JMF/ composition of mix and associated material with FHWA Form 1641 for verification at least 7 days before construction.

Include a signed statement from prepared by the testing laboratory that certifies the proposed JMF meets requirements and can be compacted in the field during production.

b. The verification process starts when required documentation and material are received. When the JMF is verified, asphalt concrete mix production may begin for the project in accordance with contractor logistics.

7. The contractor shall notify utility companies in writing of pending operations schedule as required.

8. The contractor shall employ the LA one call system for utility locations.

9. Forest Service shall stake out all locations for pot hole patching, asphalt overlay, and RV spur overlay in support of contractor operations.

10. Forest Service shall limb trees in the roadway corridor which may hinder dumping operations in support of contractor operations.

Execution:

1. Pothole patching:

a. Contractor shall saw cut and remove asphalt from potholes as marked by the Forest Service.

b. Contractor shall excavate all material to a 12” depth below existing roadway surface where asphalt overlay will be emplaced and 14” depth where the pothole is being patched to match existing surfacing.

c. Contractor shall emplace 610 road base in three lifts four inches deep.

Each lift shall be compacted to maximum density with a plate tamp.

2. 2” asphalt overlay on loop roads

a. Contractor shall provide all personnel, material, and machinery to install finished asphalt concrete surfacing on campground loop roads at an average of 2” in depth.

b. All intersections with new pavement shall be constructed within 24 hours

c. All intersection with existing pavement shall match elevations with a saw cut.

3. 2” asphalt overlay on Recreational Vehicle camping spurs.

a. Contractor shall provide all personnel, material, and machinery to install finished asphalt concrete surfacing on campground loop roads at an average of 2” in depth.

b. All intersections with new pavement shall be constructed within 24 hours

c. All intersection with existing pavement shall match surface elevations and compacted lift thicknesses with a saw cut.
