Aggregate properties for RMA shall meet the requirements of Superpave 12.5FC 2 specified elsewhere in the Contract Documents. Coarse and fine aggregate properties for Superpave 9.5 R-Gap Graded shall meet the requirements of Superpave 12.5FC 2 specified elsewhere in the Contract Documents. 1151.05.06.04 Rubberized Asphalt Cement CR added to the RAC shall meet the gradation requirements specified in Table R3 determined according to ASTM D5644. Wet-terminal blend RAC shall be produced as a Type III Asphalt Rubber Binder according to ASTM D6114. CR dosage by mass of wet-terminal blend RAC shall be 10% to 15%. Wet-field blend RAC (after reaction) shall meet the requirements found in Table R4. CR dosage by mass of wet-field blend RAC shall be 18% to 20%. For the production of the RAC, parameters such as CR gradation, mixing method and equipment, dosage, reaction time, mixing temperature, storage conditions and need for agitation, blending location (project site vs. asphalt supplier’s terminal) shall be determined by the Contractor. When the RAC supplier specifies a CR gradation with additional restrictions, the CR shall also meet the RAC supplier’s gradation requirements. The CR material, PGAC and any antistripping additives required shall be compatible to ensure a good dissolution and reaction time. RAC produced shall be a homogenous mixture of CR and asphalt cement. In case of terminal blend, the following asphalt cement suppliers have indicated their ability to supply the RAC: a) Bitumar; b) Coco; c) McAsphalt; d) Shell 1151.07 PRODUCTION 1151.07.01 Anti-Stripping Additives Subsection 1151.07.01 of OPSS 1151 is amended by addition of the following: When an anti-stripping agent is to be incorporated into the mix, the Contractor shall contact and consult with each supplier to determine whether or not the proposed anti-stripping agent is compatible with the RMA or RAC or both. In those cases where a supplier deems that the anti-stripping agent is incompatible, that anti-stripping agent shall not be used and the Contractor shall select and employ another anti-stripping agent that the suppliers indicate is compatible with the mix and RAC. 1151.07.03 Field Blending Plant The Contractor shall contact OTS a minimum of 6 weeks prior to paving Superpave 9.5 R-Gap Graded to coordinate delivery and operation of the field blending plant. OTS contact information is provided earlier in this special provision. 313.07 CONSTRUCTION 313.07.06.01 Operational Constraints Clause 313.07.06.01 of OPSS 313 is amended by addition of the following: The Contractor shall provide a minimum of 7 Days notice in writing to the Contract Administrator and to the Ministry’s Regional Head of Quality Assurance Section before paving any trial section. 37
313.07.06.02 Paving Clause 313.07.06.02 of OPSS 313 is amended by addition of the following: The Contractor shall construct the control section and trial sections as indicated in Table R1, full width including shoulders. Transition areas shall be less than 50 m in length at the start of the trial and control sections. The Contractor shall adjust the paving and compaction operations to eliminate roller pick-up and provide a smooth surface without tearing, cracking, or shoving. 313.07.15 Sampling Subsection 313.07.15 of OPSS 313 is amended by the addition of the following clause: 313.07.15.06 Rubber Modified Asphalt Samples shall not be taken from the transition areas. In addition to other samples specified in the Contract Documents, the Contractor shall procure RMA samples of a minimum quantity specified in Table R5 for each of the control and trial sections. Sample labeling shall include: highway number, highway direction, lane number, contract number, section (trial or control), mix type, corresponding Lot/Sublot numbers, station, date sampled. The Contractor shall deliver the samples specified in Table R5 to the address below: c/o Seyed Tabib Bituminous Section, MERO Shipping and Receiving Room 15, Building C 1201 Wilson Ave, Toronto, ON M3M 1J8 Section 313.07 of OPSS 313 is amended by the addition of the following subsection: 313.07.19 Identification of RMA Paving Limits The Contractor shall provide to the Contract Administrator, no later than 7 Days after completion of RMA paving, an as built sketch identifying the stations as well as the GPS data for the RMA paving limits. The GPS data shall be geo-referenced and NAD83 geographic coordinates (latitude, longitude) shall be used. Geographic coordinates (latitude, longitude) shall be provided within metre-level accuracy. 313.08 QUALITY ASSURANCE 313.08.01.02.01 Lot Size Clause 313.08.01.02.01 of OPSS 313 is amended by the addition of the following: Each mix type for the trial section shall be considered as a single lot with a minimum of three sublots. 313.08.01.02.03 Basis of Acceptance Clause 313.0.8.01.02.03 of OPSS 313 is amended by the addition of the following: a) Acceptance of Crumb Rubber 38
