Summary of Test Method4.1 Asmall section of roof surface is fabricated with roofingfelt or membrane using mea

8、sured amounts of a bituminouspour coat and mineral aggregate surfacing. The assembly isallowed to cool, the loose aggregate is removed and weighed,and the mass of adhered aggregate is calculated and reported.5. Significance and Use5.1 The quantities of mineral aggregate adhered to thesurface of a ro

9、of vary with the characteristics and total amountof the aggregate. Mineral aggregate shields bituminous mem-branes from solar radiation. Unadhered mineral aggregate canbe displaced by wind, water, and traffic, exposing the bitumen.5.2 This test method provides a laboratory means of deter-mining and
