Canyon Road

Part 1: Scope/Background/Objective

1.1 Scope

The Contractor shall source and provide 300 tons of bulk cold mix asphalt (CMA).

Contractor shall arrange delivery to the Indian Cove Campground Rattlesnake Road located at Joshua Tree National Park (JOTR). Deliveries will be on call in quantities of 50 tons until the full 300 tons have been delivered.

All vehicles making deliveries will need to undergo a weed free inspection during the initial delivery into the park. The location and time of such inspections will be determined by the Roads Foreman in conjunction with the contractor.

This project may require intermittent deliveries based on other work that comes up in the park. If so the Roads Foreman will work with the contractor to identify a date in which deliveries can resume.

1.2 Background

The park’s Roads Maintenance program has been approved to carry out a major rehabilitation project for Indian Cove’s Rattlesnake Canyon Road. The existing CMA road is decades old and has deteriorated to the point where an overlay of fresh asphalt is required.

1.2 Objective

The objective of this contract is to provide the required supply of cold mix asphalt that meet the objectives of the Maintenance Division, as well as requirements of NPS regulation and policy.
