History and development of modified bitumen

Abstract
The development of modified bitumen (MB) roofing began in Europe. Its use has spread throughout the world; MB roofing is the fastest-growing type of roofing on the market today. Because of the various types of modifiers, reinforcing and surface treatments used, the performance characteristics of the MB products available are almost unlimited. When one combines these products with the diverse methods of installation (heat welding, hot asphalt and cold adhesive) and the ways of attachment or nonattachment to the roofing base, it becomes apparent that the selection of an MB may be difficult. Not all MB roofing is equal, and the product selected must be carefully matched to the requirements of the building being roofed and to the environment in which the MB roof will be expected to perform.
