Bitumen compositions for cold applied roofing products
Physico-chemical characteristics of three-component composition BNB 70/30 bitumen : linseed oil : SBS rubber have been investigated. The composition may be used for the production of rolled roofing, the installation of which does not require heating operation. The dependence of the softening temperature, ductility, penetration, adhesion, elasticity and water resistance of bitumen compositions on their structure has been examined.
