CITY OF SANTA ANA <br />SPECIFICATIONS <br />PROJECT NO.: XX-XXXX <br />PROJECT TITLE <br /> <br />43 <br />recycling in some other means to the satisfaction of the Engineer. <br />3. Accurately referencing the profile and cross slope as shown on the plans for <br />the finished surface of the recycled pavement material. <br />C. MATERIALS <br />Cold Milled Asphalt Concrete <br />Existing asphalt concrete pavement shall be cold milled, crushed and screened to <br />conform to the following gradation before mixing with emulsified recycling agent: <br />Sieve Sizes Percentage passing <br />1-inch 100 <br />Graded millings shall uniformly be incorporated into the recycled pavement mixture <br />and oversized or deleterious material shall be disposed of. <br />Emulsified Recycling Agent <br />The type of recycling emulsion to be used shall be determined by the mix design. A <br />representative from the recycling emulsion supplier and/or the Contractor shall be at <br />the job site at the beginning of the project to monitor the characteristics and <br />performance of the recycling emulsion. Throughout the job, the representative will <br />be available to check on the project and make adjustments to the recycling emulsion <br />formulation as required, such as to improve coating or adjust breaking properties. <br />Emulsified recycling agent shall conform to the following requirements: <br /> Test Method Requirement <br />Minimum Maximum <br />Tests on emulsion: <br />Sieve test, % of weight sample AASHTO T59(1) --- 0.1 <br />Residue by distillation, % AASHTO T59(1) 60 67 <br />RAP Coating Test AASHTO T59(2) Minimum Good <br />Tests on residue by distillation: <br />Penetration, 25C, 100g, 5s <br />(Target Value) (3) <br />AASHTO T49(4) +/- 25% <br />Absolute Viscosity at 60C, poise AASHTO T2171(4) Report Only <br />Notes: <br />1. Modify AASHTO T59 - distillation temperature of 177C with a 20 minute <br />hold. <br />2. Mix emulsified recycling agent and water rates shall be determined by the mix <br />design and with jobsite RAP. <br />3. Target value shall be determined by the mix design. <br />4. Sieve residue from distillation on #20 sieve prior to determining viscosity. <br />505 E Central Ave <br />#B11/6/2024
