8、minous sheet materials reinforced with acombination of polyester fabric and glass fiber reinforcement,Type I, Type II and Type III are covered by this specification.4.2 The following grades are used to describe the materialsurfacing:4.2.1 Grade GGranule surfaced.4.2.2 Grade SSmooth surfaced.5. Mater
9、ial and Manufacture5.1 In the process of manufacture, the reinforcement issaturated with asphalt or modified asphalt and is impregnatedand coated on both sides with an SBS modified bituminouscoating. The SBS modified bituminous coating shall be per-mitted to be compounded with a mineral stabilizer.5
10、.2 The Grade G sheet is surfaced on the weather side withmineral granules, except for any selvage. To prevent sticking inthe roll, the reverse side and any selvage shall be permitted tobe covered with a mineral or any other surfacing that will notinterfere with adhesion or bonding of the lap during
11、applica-tion.5.3 Sheet material intended for application by heat welding(torching) shall meet the minimum bottom coating requirementfound in Table 1.6. Physical Properties6.1 The sheet shall conform to the minimum physicalproperties prescribed in Table 2.6.2 The finished product shall not crack nor
12、be so sticky asto cause tearing or other material damage upon being unrolledat any product temperature between 4 and 60C (40 and140F).7. Dimensions, Mass, and Permissible Variations7.1 The finished product shall conform to the followingdimensions and variations:7.1.1 The width of the roll shall be a
13、s agreed between thepurchaser and the seller and shall not vary more than 1 %.7.1.2 The area of the roll shall be no less than as agreedbetween the purchaser and the seller.7.1.3 The selvage width shall be within 6.4 mm ( in.) ofthe nominal selvage width and shall be not less than 76.2 mm1This speci
