CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 55 liquid asphalt formulation as required, such as to improve coating or adjust breaking properties. The Contractor shall provide current test results and a Certificate of Compliance for liquid asphalt at the time of mix design submittal and for each load delivered to the jobsite. For bidding purposes, the emulsified recycling agent content is assumed to be 2.4%. Water Water shall be added to facilitate the uniform mixing of the liquid asphalt and the cold milled material. Water used for cold recycling shall be clean and free of foreign substances and shall not cause an adverse effect on either the liquid asphalt or the recycled pavement mixture. Water added by the milling machine shall be measured, and the rate of added water can be between 0.5 and 5.0 percent of water added by weight of the recycled pavement mixture per the approved mix design unless a greater variation has been directed by the person designated by the Contractor to make adjustments in the field. The quantity of residual recycling agent in the final recycled pavement mixture shall not vary due to the addition of water. Additives No additives shall be allowed in the cold recycled pavement. D. MIX DESIGN At least 14 days prior to beginning the recycling operation, the Contractor shall submit a CIREAM mix design to the Engineer. The mix design shall be prepared under the supervision of and signed by an Engineer licensed by the State of California. Prior to commencing the work, the Contractor shall obtain samples that are representative of the material that will be produced during the milling operation. Samples used in the mix design shall be obtained directly from the project site either by coring or milling, as approved by the Engineer. These samples shall be used to establish the design rate of expanded asphalt as a percent by mass of the recl aimed asphalt pavement. The design rate of the expanded asphalt shall be a minimum of 1.0%. Based on the characteristics of the reclaimed asphalt pavement taken from the project site, more than one mix design may be required. The mix design for the recycled pavement mixture shall conform to the requirements in the Wirtgen Cold Recycling Manual’s Appendix A2.3. The CIREAM shall meet the following minimum physical requirements: Property Minimum Requirement Dry Tensile Strength 50 psi Wet Tensile Strength 25 psi Tensile Strength Ratio (TSR) 50% 505 E Central Ave #B11/6/2024
