CITY OF SANTA ANA <br />SPECIFICATIONS <br />PROJECT NO.: XX-XXXX <br />PROJECT TITLE <br /> <br />45 <br />The recycled pavement mixture shall conform to the following quality requirements <br />throughout cold in-place recycling operations: <br />Cold In-Place Recycling Mix Requirements <br />A. Design Parameters <br />Requirement <br />Gradation of Reclaimed Asphalt Pavement (RAP): CT 202 1-inch <br />Asphalt Content of RAP: CT 362 or CT 379 or ASTM D 2172 <br />Method B <br />Report <br />Bulk Specific Gravity of Compacted Samples (1)(2): CT 308 <br />Method C Report <br />Maximum Theoretical Specific Gravity (2): CT 309 (including <br />provisions of Section J) Report <br />Air Voids of Compacted and Cured Specimens (2): CT 367 Part B Report <br />Marshall Stability, Cured Specimen(2): AASHTO T 245 40°C <br />(104°F) <br />1,250 lb. <br />Minimum <br />Marshall Retained Stability, AASHTO T 245, 40°C (104°F) <br />Based on Moisture Conditioning on Cured Specimen (2)(3) 70% minimum <br />Ratio of Emulsion Residue to Cement (weight : weight) 3:1 <br />Minimum <br />Raveling Test, Section 9 of Lab Procedure 8, 10°C (50°F) Report <br />Notes: <br />1. 100 mm diameter mold compaction based on either 75 blow Marshall each <br />side or gyratory compactor at 30 gyrations. <br />2. Measurement on specimens after 60°C (140°F) curing to constant weight for <br />no less than 16 hours and no more than 48 hours. <br />3. Vacuum saturation of 55 to 75 percent, water bath at 25°C (77F) for 23 <br />hours, last 30 to 40 minutes in 40°C (104F) water bath. <br />During the mix design, the Contractor shall determine the target values for <br />penetration at 25°C and viscosity at 60°C of the emulsified recycling agent to be used <br />in production of the recycled pavement mixture. <br />The mix design report shall include gradation of millings; recommended water <br />content range as a percentage of dry millings; optimum emulsion content as a <br />percentage of dry millings; and corresponding density, air void level, absorbed water, <br />Marshall stability, retained stability, and raveling at recommended moisture and <br />emulsion contents. For the emulsified recycling agent, include the designation, <br />company name, location, residue content, and certificates of compliance. <br />Contractor Responsibility <br />The Contractor is responsible for the final product. Adjustments shall be made in the <br />field to the actual application rate of emulsified recycling agent as needed, as <br />505 E Central Ave <br />#B11/6/2024
