Description / Abstract:
This specification covers SEBS (styrene-ethylenebutylene-
styrene)-modified asphalt intended for use in built-up roof
construction, construction of some modified bitumen systems,
construction of bituminous vapor retarder systems, and for adhering
insulation boards used in various types of roof systems.
This specification is intended as a material specification.
Issues regarding the suitability of specific roof constructions or
application techniques are beyond its scope.
The specified tests and property values used to characterize
SEBS-modified asphalt are intended to establish minimum properties.
In place system design criteria or performance attributes are
factors beyond the scope of this specification.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
This standard does not purport to address the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
