Resurface SATF Asphalt Traction Test Pad

DRAFT STATEMENT OF WORK

C.1 BACKGROUND

The National Highway Traffic Safety Administration (NHTSA) has a need to resurface the asphalt test surface portion of the Traction Grading Test Track used to perform testing in accordance with the Uniform Tire Quality Grading System (UTQGS) at the Office of Vehicle Safety Compliance’s (OVSC’s) San Angelo Test Facility (SATF) located on the grounds of Goodfellow Air Force Base (GAFB) in San Angelo, Texas (TX). The asphalt test surface was last resurfaced in September 2013. The test surface is used by OVSC to perform traction testing for enforcement of the UTQG consumer information program. The test surface is also used by outside entities to perform traction testing.

The UTQG traction test measures the slide friction coefficient of tires using a tire traction skid trailer at a test speed of 40 miles per hour (MPH). The allowable surface coefficient range per 49 C.F.R. § 575.104 is 0.50 ± 0.10. This value is measured using the American Society for Testing and Materials (ASTM) E 501 tire with a test load of 1,085lbs and an onboard watering system with an output of approximately 4.0 GPM per wetted inch of nozzle width.

C.2 CONTRACT OBJECTIVES

The objective of this contract is to replace the asphalt UTQG traction test surface located at the SATF located on GAFB in San Angelo, TX with a durable surface that meets the tire test surfaces specified in 49 C.F.R. § 575.104.

This may include, but is not limited to, identifying a suitable replacement asphalt mix with test strips, removing the existing surface, placing a new asphalt surface, and re-painting the required lines.

C.4 TEST SURFACE SPECIFIC REQUIREMENTS

C.4.1 KICK-OFF MEETING

Within two (2) weeks of the effective date of the contract, the Contractor shall participate in a Kick-Off meeting with the Contracting Officer’s Representative (COR), Contracting Officer (CO), and other NHTSA staff. The Kickoff meeting will take place via teleconference and will be approximately two hours in length. The Contractor shall make a brief presentation of their understanding of the contract requirements. After the presentation, the parties shall discuss basic contract requirements, including the schedule for evaluations and operational procedures.

Washington, DC, based NHTSA staff may join via teleconference for these discussions.

C.4.2 The Contractor shall clean and remove all grass, weeds, debris, and soil from cracks in the asphalt test surface prior to beginning paving.

C.4.3 If the contractor deems it necessary to meet the requirements of this solicitation, the Contractor shall remove the existing surface as needed; or subject to COR approval repair the existing asphalt test surface with a suitable asphalt crack sealant.

C.4.4 The Contractor shall prepare and install an asphalt and aggregate seal coat overlay on the entire test surface and shoulders, 1000 feet long and 104 feet wide, that will serve in part as a moisture barrier.

C.4.5 The Contractor shall provide an initial asphalt mix design that meets the required performance characteristics using the test methods detailed in Section C.4.6 prior to applying the first test strip. The government will provide historical mix design documentation as reference material for the contractor if desired.

a. The Contractor shall prepare and install an initial test strip before installing the full asphalt test surface. The Contractor shall ensure the test strip is 10 feet wide and 150 feet long in the shoulder area of the asphalt test surface. The purpose of the test strip is to validate that the mix design will provide the required wet traction coefficient of friction as stated in C.4.6 below. The validation process will be:

1) Once the surface has cured (approximately 2 weeks depending on weather) the government will burnish and test the surface for wet traction coefficient of friction. This process may take as much as 3 weeks.

2) The government will discuss the results of the testing with the contractor.

b . If an additional test strip is required; the following procedure will be followed:

1) The Contractor shall then adjust the asphalt mix design as required to meet the friction coefficient requirements and install another complete asphalt test strip in the same general area as the previous one; as described in paragraph (C.4.5.a, above). The contract requires successful paving of at least one test strip that meets the required wet traction coefficient of friction prior to receipt of approval to move onto Phase 2 for paving of the full asphalt test surface.

2) Once the government determines that the test strip meets skid coefficient requirements, the contractor will be notified by the COR that it may proceed to the task detailed at C.4.6 below.

Phase Two (2) Full Asphalt Test Surface Application

C.4.6 The Contractor and government shall work together to achieve a wet slide coefficient of friction within the acceptable range of 0.55µ to 0.62µ after curing and the government has burnished the surface. The coefficient of friction will be measured by the government using the UTQG traction test procedure and an ASTM E 501 tire. The timeline between test strip approval and final test surface application shall be no longer than 1 month with exceptions for weather delays and hot mix asphalt plant availability.

C.4.7 Additional Construction Requirements

a. The test procedure requires a traction testing apparatus consisting of a pickup truck and instrumented trailer to travel at a steady speed of 40 MPH. The Contractor shall construct the new asphalt test surface in a way that allows for a very smooth transition from the oval track road to the test surface with no perceptible impact to the driver and enough distance for the vertical loads to settle out of the suspension prior to reaching the first test location. The Contractor shall ensure the exit ramp of the test surface meets the same requirements. The Contractor shall ensure that the surface transition is smooth from both directions if traffic flow needs to be reversed.

b. The Contractor shall ensure that the final test surface is smooth and free of bumps, divots, or any other surface disturbances. These things will cause transient disturbances in traction testing data which will increase test variability and produce bad data.

c. The Contractor shall ensure that there are no foreign objects purposefully or accidentally left in the test surface. The Contractor shall ensure that the surface is a smooth, finished, homogenous, asphalt surface.

d. The Contractor shall ensure that there are no longitudinal or horizontal cracks in the final test surface. The Contractor shall ensure that the construction seams between asphalt lays are minimal with no vertical difference between lays.

e. The Contractor shall determine the recommended overlay thickness and the final density such that the surface can support the static and dynamic loads of the trailer traction testing apparatus for the extent of the test surface life (8 years) without rutting or significant cracking.

1. The trailer traction test vehicle is a Ford F350 pickup truck with test equipment installed. The fully loaded vehicle weight is approximately 13,500 lbs. and the test surface will experience an annual average daily traffic (AADT) of approximately 40.

C.4.8 At transition areas between the test surface and the non-test surface, the Contractor must provide:

a. Butt joints to transition to and from asphalt test areas to ensure structural integrity and smooth transition to the asphalt roadway surface.

b. Provide a smooth transition between the test surface and the non-test surface, such that, the driver of an instrumented skid trailer driving over the transition area will not feel a bump and the data acquisition system will not be affected as the various axles pass over the transition area.

c. Two full-width, ramp-like surface grades of 100 feet length each. The Contractor shall ensure that each grading has a gradual height transition from the original non-test asphalt surface with overlay to the existing concrete test surface.

C.4.9 The Contractor shall paint new lane stripes on the new test surface that duplicate the color, width and length of the old lane stripes, i.e., alternating yellow and white stripes, 10 feet long, beginning 10 feet prior to entering skid pad test surface from both directions and a lateral midpoint stripe.

C.4.10 The government will evaluate the completed test surface and provide final acceptance to the contractor. The government will provide final acceptance within two (2) months of the completion of the lane stripes being completed.

C.4.11 The Contractor shall provide all quality assurance or quality control data and documentation for any of the materials and test surface along with the final mix design to the COR. These documents must be provided within 3 weeks of the government’s final acceptance of the completed test surface.
