CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 57 Some sections of the pavement being recycled may require field adjustment for optimum results. For any changes made by the Contractor from one lot to the next, the Contractor shall document the reason for the change and identify each lot where such changes were made. E. TEST STRIP AND START UP PROCEDURES The first day of operations, the Contractor shall construct within the limits to be cold recycled a test strip of a single lane width and no more than 1000 feet in length. The test strip section shall: 1. Demonstrate that the equipment, materials, and processes proposed can produce a recycled pavement material layer that conforms to the requirements of these special provisions. 2. Determine the optimal rates for liquid asphalt and water recommended for the reclaimed asphalt pavement. 3. Determine the sequence and manner of rolling necessary to obtain the density requirements of these special provisions. The Contractor shall provide a sequence and manner of rolling which will define maximum compaction by establishing a rolling vs. density chart that shows the progress of densification from initial laydown through maximum obtainable density at the “break over point”. The Contractor shall determine relati ve compaction on the quantity within the test strip by measuring nuclear gage density. If the relative compaction of quantity within the test strip or any lot does not meet the density requirements of these special provisions, the Contractor shall construct additional test strips to define the maximum density obtainable for the millings being produced; the rates of liquid asphalt and water; and the site conditions. Cold recycling operations may continue through the first day, unless the Contractor’s equipment and process fail to meet the requirements for successful completion of cold recycling operations in conformance with these special provisions. Recycling operations shall not continue until a test strip conforming to the special provisions has been constructed and approved by the Engineer. Test strips that do not conform to the special provisions shall be reworked, re-compacted, or removed and replaced at the Contractor's expense. Upon acceptance of the test strip by the Engineer, the Contractor shall use the same equipment, materials, and construction methods for the remainder of recycling operations, unless adjustments are made by the Contractor and approved by the Engineer. If adjustments are made, the Contractor will produce a new test strip to define the maximum density. 505 E Central Ave #B11/6/2024
