Book Description
The resistance of bituminous built-up roofing membranes to thermally induced forces is considered in terms of their strength properties such as breaking load in tension, modulus of elongation and apparent linear thermal expansion coefficient.The development of a Thermal-Shock Resistance Factor is described and values are given for three bituminous built-up membranes at temperatures of - 30F (-34.4C), 0F (-17.8C), 30F (-1.1C) and 73F (22.8C).The apparent relation between the values obtained in the laboratory and the observed performance of roofing membranes in service is considered.The utilization of the Thermal-Shock Resistance Factor in the reduction of potential failures of bituminous built-up roofing membranes in service from thermally induced forces is also discussed.(Author).

Book Description
This report is the first in a series of publications on performance criteria for built-up roof membranes. The development of a performance approach to bituminous built-up roof membranes is described and preliminary performance criteria are recommended. A number of test methods have been developed in order to obtain data to evaluate roofing membranes against the recommended criteria. Twenty attributes that effect the performance of roof membranes under service conditions are identified and laboratory tests are described for measuring the engineering properties of the membrane that pertain to many of these attributes. A level of performance is recommended for nine of the identified performance attributes.
