ASTM D6152/D6152M-12 (R2018) PDF Download

The ASTM D6152/D6152M-12 (R2018) standard is a specification that covers SEBS (styrene-ethylenebutylene-styrene)-modified mopping asphalt. This asphalt is intended for use in various roofing applications, including built-up roof construction, construction of some modified bitumen systems, construction of bituminous vapor retarder systems, and for adhering insulation boards used in different roof systems.

The purpose of this specification is to establish minimum properties for the SEBS-modified asphalt. It is important to note that this specification is focused on the material itself and does not address issues related to the suitability of specific roof constructions or application techniques. Design criteria and performance attributes of installed systems are beyond the scope of this standard.

The specified tests and property values outlined in the standard cover a range of physical properties of the SEBS-modified asphalt. These include softening point before and after heat exposure, softening point change, flash point, penetration before and after heat exposure, penetration change, solubility in trichloroethylene, tensile elongation, elastic recovery, and low-temperature flexibility. The standard also provides detailed guidance on sampling and test methods for determining compliance with these physical properties, as well as evaluating stability during heat exposure.

It should be noted that this standard does not address safety concerns associated with the use of SEBS-modified mopping asphalt. It is the responsibility of the user to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations before using this material.
