CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 44 The Contractor shall provide current test results and a Certificate of Compliance for emulsified recycling agent at the time of mix design submittal and for each load delivered to the jobsite. During cold recycling operations, the Contractor shall obtain two 1-liter samples of emulsified recycling agent from each load delivered to the project. One sample shall be used for the Contractor’s quality control testing. The remaining samples shall be delivered to the Engineer at the end of each working day. Emulsified recycling agent shall be sampled in plastic containers that are clean, dry, and sealed. The emulsified recycling agent sample shall be handled with care. For bidding purposes, the emulsified recycling agent content is assumed to be 3.5%. Water Water may be added to facilitate the uniform mixing of the emulsified recycling agent 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 emulsified recycling agent 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 Cont ractor shall submit a cold recycled asphalt concrete 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. The Contractor shall determine the rate of emulsified recycling agent to be added to the cold milled reclaimed asphalt pavement as part of the mix design for the recycled pavement mixture. Reclaimed asphalt pavement used in the mix design shall be obtained directly from the project site either by coring or milling, as approved by the Engineer. Based on the characteristics of the reclaimed asphalt pavement taken from the project site, more than one mix design may be required. If this process is used, the city may provide mix design requirements. If so, th e mix design for the recycled pavement mixture shall conform to the requirements indicated in the – Lab Procedure “Method of Test for Determining the Percent of Emulsified Recycling Agent to Use for Cold Recycling of Asphalt Concrete”. As part of the mix design collection of core samples, the Contractor shall also perform dynamic cone penetrometer (DCP) testing to determine the condition of the base. Both the core and DCP results shall be submitted to the Engineer to determine the proper treatment of a given roadway segment. 505 E Central Ave #B11/6/2024
