in the lowest third of each storage tank. If the plant has been equipped with a water injection type asphalt foaming system, ensure that the system will allow the proper amount of asphalt rubber binder to be supplied continuously or provide a by-pass to ensure that the proper amount of asphalt rubber binder is supplied to the mix. 189
Appendix T: Massachusetts Asphalt Rubber Specifications SECTION 466 STRESS ABSORBING MEMBRANE INTERLAYER DESCRIPTION 466.20 General. This work consists of the application of hot, rubberized asphalt to a paved surface and immediately embedding aggregate therein by spreading and rolling in accordance with these specifications. This item may also be referred to as SAMI. MATERIALS 466.40 General. Asphalt: Asphalt cement for the asphalt rubber mixture shall be AC-10 or AC-20, complying with the requirements of M3.01.0. If AC-10 is used, the SAMI shall be overlayed within ten (10) days. Rubber: The granulated rubber shall be a vulcanized rubber product from the ambient temperature processing of pneumatic tires. The granulated rubber type shall meet the following gradation: Sieve Designation Percent Passing 2.36 mm 100 2.00 mm 95-100 1.18 mm - 600 •m 0-10 300 •m 0-5 Aggregate shall conform to the requirements of M2.01.0 for crushed stone. Crushed gravel stone will not be permitted. Gradation requirements will conform to M2.01.6. Percentage of wear as determined by the Los Angeles Abrasion Test (AASHTO T 96) shall be a maximum of 30. CONSTRUCTION METHODS 466.60 General. Preparation of Existing Surface. Prior to application of the rubberized asphalt, the entire paved surface to be treated shall be cleaned by sweeping, blowing and other methods until free of dirt and loose particles. Pot holes, depressions, cracks larger than 20 millimeters and other irregularities will be patched with hot bituminous mix and compacted. No water shall be present on the surface. A levelling course shall be placed on planed, milled or existing surface if required. Seasonal and Weather Limitations. Construction shall not proceed when the ambient temperature has been below 10 °C within the previous 12 hours, when rain is falling, or when conditions are unfavorable to obtaining a uniform spread. 466.61 Asphalt Rubber Mixing and Reaction The percent of rubber shall be 23 ± 2% as indicated by the mixture design for specific project 190
