The asphalt residue recovered from distillation according to AASHTO T 59 shall be according to the requirements of ASTM D 449, Type I, asphalts for waterproofing, with the exception; the ring and ball Waterproofing Materials Art. 1060.09 softening point shall be excluded. In addition, the material shall meet the moisture retention requirements specified in Article 1022.01 and shall pass the following tests.
a.Resistance to Water Action. When tested according to ASTM D 466, no lifting of the film or darkening of the water will be permitted.
b.Freeze Recovery. Freeze recovery shall be tested in the following manner. Soak an unglazed ceramic tile, as used in ASTM D 466, in distilled water for ten minutes. Then place the tile in a freezer until the ice crystals form on the surface, at which time the tile is removed from the freezer and immediately coated with emulsion at room temperature as per ASTM D 466. The coated tile is then replaced in the freezer. After five hours, the tile is removed from the freezer and dried as per ASTM D 466. After drying, the tile is tested as per ASTM D 466. No lifting of the film or darkening of the water will be permitted.
c.Rain Resistance. Rain resistance shall be tested as follows. Dampen 3.5 oz (100 grams) of dry 1/4 to 3/8 in. (6 to 9 mm) stone chips with 0.04 oz (1 g) of water. Add 0.18 oz (5 g) of emulsion to the damp chips and mix for two minutes. When mixing is completed, place the coated chips on a screen and immerse them in a container of water at room temperature allowing them to soak one minute without movement. After soaking, remove from the water and examine for loss of coating. No loss of coating will be permitted.
1060.09 Butyl Rubber Membrane. Butyl rubber membrane shall be 1/8 in.
(3 mm) thick. Rubber membrane shall be a compound butyl elastomer of the IIR Family (Isobutylene-Isoprene rubber) according to the following.
