CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 46 provided by these special provisions, based on the opinion of the Contractor. Any changes made by the Contractor shall be documented in conformance with these special provisions. The Contractor shall perform process and quality control sampling and testing, and exercise management control to ensure that cold recycling and placement conforms to these specifications. The Contractor shall provide a testing laboratory and personnel to perform process and quality control sampling and testing during the cold recycling, spreading, compaction, and finishing. The proficiency of testing laboratories and sampling and testing personnel shall be reviewed and approved by the Engineer prior to providing services to the project. Sampling and testing shall be performed at a rate sufficient to ensure that cold recycling, placement, compaction, and finishing conforms to these specifications. The Engineer shall have unrestricted access to the laboratory, sampling, testing sites, and all information resulting from mix design and quality control activities. All quality control testing results shall be submitted to the Engineer on a daily basis. The project shall be divided into lots of not greater than 1500 square yards. The Contractor shall control the cold recycling operation as follows: 1. The Contractor shall measure and record the actual recycle depth at each end of the milling drum at least once every 350 feet along the cut length. 2. The amount of emulsified recycling agent shall be within 0.5 percent of the job mix formula established in the mix design for the cold recycled asphalt concrete mixture. Emulsion usage shall be recorded for each lot. The percent of emulsified recycling agent shall be determined based on the ratio of emulsion used to the theoretical dry weight of the millings processed. 3. The Contractor shall measure and report in-place density, and relative compaction for the lot, and shall rework or reprocess any lot not meeting the requirements of these specifications. 4. Sample the recycled material behind the recycling equipment or the sized reclaimed asphalt pavement prior to the addition of the emulsified recycling agent for each lot. If the reclaimed asphalt pavement does not meet the allowable maximum particle size, the test results shall be reported immediately to the Engineer. The Contractor shall reprocess the material or take other corrective actions to attain conformance. 5. On every third sample taken, the Contractor shall perform a wet field gradation for material passing the 1-inch to No. 4 sieves. The Contractor shall compare the sieved sample to the gradation band determined from the mix design and adjust the emulsified recycling agent as needed. 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, 505 E Central Ave #B11/6/2024
