Table 10. Design Parameters for Asphalt Rubber Chip Seal Interlayers (SAMI) Agency Binder Chips Notes California/Caltrans Asphalt rubber field blend the same as hot mix. Binder application rate 2.5 - 3.0 L/m 2 (0.55 – 0.66 gal/yd 2 ) Arizona DOT CRM gradation shall be Type A coarser one. Binder application rate: 0.55 ± 0.05 gal/yd2. Florida DOT Use ARB20 with 20% CR. Binder application rate is 0.6-0.8 gal/yd 2 . Massachusetts DOT AC-10 or AC-20 as base asphalt. The percent of rubber shall be 23 ± 2%. Chip seals 12.5 mm; 9.5 mm gradation; Chip seal application rates are 15-22 kg/m 2 . Uniform size aggregate 9.5 mm. Aggregate application rates shall be 0.014 cubic yards/yd 2 . Use No 6 stone, slag, or gravel. Spread the chip aggregate at a rate between 0.26 and 0.33 ft 3 /yd 2 Shall be crushed stone. Crushed gravel stone is not allowed. Should be precoated rock. Application rate, 15-20 kg/m 2 . Rock shall be pre-coated. No flush coat. No sanding on SAMI. Rock shall be pre-coated with 0.40 to 0.60 % asphalt cement by weight of the aggregate. If the asphaltrubber membrane has been subjected to traffic, a tack coat, as herein before specified, shall be applied at the rate of approximately 0.06 gal/yd 2 prior to placement of the asphaltic concrete. Ensure a well-bonded interlayer by adjusting the thickness and temperature of the initial layer of asphalt concrete. Pot holes, depressions, cracks larger than 20 millimeters and other irregularities will be patched with hot bituminous mix and compacted. For spraying and/or better “wetting” of the cover material, a diluents, Grade #1 Fuel Oil,
8.2 Construction of Asphalt Rubber Chip Seal Interlayer Table 11 shows the construction related project information for the Asphalt Rubber Chip Seal Interlayers used by different agencies. Table 11. Requirement during Asphalt Rubber Chip Seal Interlayer Construction Agency Ambient/pavement temperature California/Caltrans Pavement ≥ 13 o C (55 o F); The ambient air temperature should be 16-43°C (61-109F). Binder Temperature The binder application temperature is 196-213°C (385-415 o F). Chip Rock Temperature Chip application temperatures107- 163°C (225- 325F). Compaction Minimum of one complete coverage with one or more pneumatictired rollers and shall begin within 90 seconds following the placement of the screenings. Distance between the rollers and the screenings spreader shall not exceed 60 m. A minimum of 3 complete coverages. Sweeping shall be a multi-step operation. 20
