The felt may be reinforced with random, orparallel oriented glass yarns, or both, which may be gathered ortwisted, bonded or unbonded. The felt shall contain a water-insoluble agent.4.2 In the process of manufacture, the gla
7、ss mat shall beuniformly impregnated and coated on both sides with anasphaltic material, permitted to be compounded with a mineralstabilizer.4.3 The weather side shall be uniformly surfaced withmineral granules firmly embedded in the asphaltic coating,except for any selvage.4.4 The reverse side shal
8、l be covered with a material toprevent sticking in the roll.5. Physical Properties5.1 The material shall conform to the dimensions andmasses prescribed in Table 1 and areas prescribed in Table 2.5.2 The finished product shall not crack nor be so sticky asto cause tearing or other damage upon being u
