CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 51 unless the pavement temperature is a minimum of 60°F and ambient temperature is a minimum 50°F and rising. If the temperature does not meet these requirements, the Contractor shall either be put on hold until the temperature reaches the specifications above or be required to use the Cold In-Place Recycling Expanded Asphalt Mix (CIREAM) treatment at the discretion of the Engineer. No additional compensation will be allowed for putting the Contractor on hold. Recycling operations other than compaction shall be completed a minimum of two (2) hours before sunset. Where possible, ½ inch of existing asphalt concrete shall be protected in place during the grinding process to avoid exposure of existing subgrade. On street segments where it is not feasible to retain ½ inch of existing subgrade, the Contractor shall reduce the milled section or replace the proposed section as directed by the Engineer. The Contractor shall ensure in the CIR method that there is no gap of un-recycled pavement material created between successive cuts (along the same longitudinal cut line), nor wedges of un-recycled pavement material created by the entry of the milling drum into the existing material. Longitudinal joints between successive cuts shall overlap a minimum of 3-inches. In areas where the CCPR method is utilized and the recycled pavement is to be placed on the existing milled pavement surface, it shall be verified that the milled surface is firm and unyielding and there are no subgrade failure areas beneath the milled surface that might compromise the integrity of the recycled pavement. When CCPR pavement is placed on a milled surface or adjacent to structures such as curbs, concrete gutters, swales, planters, etc., these contact surfaces shall be swept of all loose material to create a dry clean surface. A tack coat of SS-1h emulsion, emulsified recycling agent or equivalent (0.05 gallon per square yard minimum) shall be applied to surface areas prior to placing the recycled pavement. J. SPREADING AND COMPACTION Prior to pick up or placement in the paver, remove and dispose of all visible oversized crack filler in the cold milled material or in the recycled pavement mixture. When a paving fabric is encountered during the recycling operation, the Contractor shall make the necessary changes in equipment or operations so that incorporation of the shredded fabric in the recycled material does not affect gradation, or inhibit placing or compaction of the recycled material. No fabric piece incorporated into the recycled section shall have any dimension exceeding a length of two (2”) inches. The Contractor shall be required to remove and properly dispose of oversized pieces o f paving fabric as directed by the Engineer. The recycled pavement mixture shall be graded and compacted to the depth, lines, and grades established by the plans or Engineer and as required by these special provisions. The recycled pavement mixture shall exit from the mixing chamber in a manner that prevents particle segregation. Care shall be exercised while spreading to avoid segregation, tearing, or scarring of the final compacted surface. 505 E Central Ave #B11/6/2024
