SCOPE OF WORK

Micro Surfacing and Pavement Marking Application &

Removable Flexible Delineator Installation Jenny Lake One-Way

Grand Teton National Park

I. GENERAL

A. Background Information: This Scope of Work (SOW) outlines tasks to apply a polymer-modified micro surfacing mix, new pavement markings, and install removable flexible delineators to the one-way section of the Jenny Lake Road, also known as the Jenny Lake One-Way (JLOW) in Grand Teton National Park (the Park).

The JLOW is a 2.5 mile long, 18’ wide paved, one-way road with a striped bicycle lane from its intersection with String Lake Road to its intersection with the Teton Park Road. To address safety concerns, the road will be restriped to allow for one-way vehicle traffic and two-way bicycle traffic.

The contractor will be allowed to close the road for up to four days to complete the work.

Due to the impacts of weather and the need for public notification of work, the contractor will coordinate with the Contracting Officer’s Representative (COR) to set the exact date and time of work performance between 3 and 5 business days prior to work. This area requires a road closure for the work to be performed so advanced public notification by the park to the public is required.

II. SPECIFICATIONS AND SCOPE

A. Description of Work: The work will consist of the Contractor, in accordance with local, state, and federal regulations, and the terms and conditions of the solicitation/contract, providing all labor, supervision, materials (unless specified elsewhere in this Scope of Work), tools, equipment, supplies, transportation, vehicles, and other items, services and incidentals necessary to apply micro surfacing and apply pavement marking in the new layout to the JLOW. All work required by the project documents to complete the work successfully and satisfactorily in its entirety will be performed by the Contractor.

B. Location: The 2.5 mile one-way section of the Jenny Lake Road begins with its intersection with String Lake Road to its intersection with the Teton Park Road in Grand Teton National Park.

This work does not include Jenny Lake Lodge Parking or Jenny Lake Overlook Parking (except as noted on details) but does include all other turnouts.

(1) See Table 703-8 for aggregate gradations.

1. Note: Micro surfacing mixture to be applied to the Jenny Lake One-Way from its intersection with the String Lake to its intersection with the Teton Park Road. Do not apply micro surface to the Jenny Lake Lodge Parking Area or the Jenny Lake Overlook, except for areas under the stop bars, new turn arrows, and new hatching.

2. Fog the surface with water in front of the spreader.

3. Prior to starting application of micro surfacing, calibrate each mixing unit to be used on the project in accordance with ISSA A143. Clean the spreader box prior to start of each work shift.

4. Blend the additives with the aggregate. Pre-wet the aggregate in the pugmill before mixing with the polymer-modified emulsified asphalt.

5. Mix the surfacing material a maximum of 4 minutes. Ensure the mix is of uniform consistency as it leaves the mixer and conforms to the approved JMF. Adjust mineral filler and polymer-modified emulsified asphalt content during construction when approved by the CO to adjust for variations in field conditions.

6. Carry sufficient mix in the spreader to completely cover the surface. Spread the mix with a spreader box. In areas not accessible to the spreader use hand squeegees to work the mix.

7. Maintain quality control documentation and make available to the CO upon request and at completion of work. At a minimum of 4 times daily calculate the percent emulsion content, aggregate spread rate, and yield of the mixture from the equipment computer display readings and report to the CO.

8. Provide straight lines along curbs and shoulders and do not allow runoff onto these areas.

Provide straight and neat starting and ending joints by masking surfaces at the start, end, and other locations as directed by the CO.

9. For transverse joints, use a butt joint. Use building paper placed over previously placed micro surfacing or other suitable method to avoid double placement of micro surfacing.

Remove ridges or bumps in the finished surface.

10. For longitudinal joints, place joints on lane lines. Use half passes and odd-width passes only in turnouts and parking areas. Do not use half passes for the last pass in paved areas.

Overlap longitudinal joints no more than 3 inches (75 millimeters). Limit the elevation difference at joints to less than ¼ inch (6 millimeters).

11. Allow treated areas to cure completely before opening to traffic. Cure is complete when clear water can be pressed out of the placed mix with a piece of paper without discoloring the paper.

12. Remove streaks and transverse ripples as defined by ISSA A143 from the finished surface.

Ensure the finished micro surfacing has a uniform texture free of scratches, tear, and other surface irregularities. Repair areas with surface irregularities or where the micro surfacing does not conform to the job-mix-formula at the direction of the CO.

13. Remove and dispose of material spills and associated debris appropriately at the end of each day.

14. Perform an initial vacuum sweep of the micro surfacing one day after the micro surfacing application. Remove loose or shedding material from the treated surface areas.

15. Two weeks to one month after completion of micro surfacing application, sweep the entire treated surface.
