Standard Specification for SEBS-Modified Mopping Asphalt Used in Roofing
Standard Specification for SEBS-Modified Mopping Asphalt Used in Roofing
ABSTRACT This specification covers SEBS (styrene-ethylenebutylene-styrene)-modified mopping 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 roofing systems. This specification is intended as a material specification and issues regarding the suitability of specific roof constructions or application techniques are beyond its scope. The specified tests and property values are intended to establish minimum properties. In place system design criteria or performance attributes are factors beyond the scope of this specification. The base asphalt shall be prepared from crude petroleum and the SEBS-modified asphalt shall incorporate sufficient SEBS as the primary polymeric modifier. The SEBS modified asphalt shall be homogeneous and free of water and shall conform to the prescribed physical properties including (1) softening point before and after heat exposure, (2) softening point change, (3) flash point, (4) penetration before and after heat exposure, (5) penetration change, (6) solubility in trichloroethylene, (7) tensile elongation, (8) elastic recovery, and (9) low temperature flexibility. The sampling and test methods to determine compliance with the specified physical properties, as well as the evaluation for stability during heat exposure are detailed. SCOPE 1.1 This specification covers SEBS (styrene-ethylene-butylene-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. 1.2 This specification is intended as a material specification. Issues regarding the suitability of specific roof constructions or application techniques are beyond its scope. 1.3 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. 1.4 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 nonconformance with the standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D6152/D6152M-12(2024) is the standard specification developed by ASTM International for SEBS-modified mopping asphalt used in roofing applications. This material specification identifies the minimum physical property requirements and testing methods for styrene-ethylene-butylene-styrene (SEBS) polymer-modified asphalts. The standard targets use in built-up roof construction, certain modified bitumen systems, bituminous vapor retarders, and the adhesion of insulation boards for a diverse range of roofing systems. With SEBS as the primary polymeric modifier, the specification ensures the roofing asphalt is homogeneous, free of water, and possesses enhanced flexibility, durability, and handling properties.
Material Scope SEBS-modified asphalts covered by this standard are intended for:
Physical Property Requirements The specification sets minimum requirements for critical material properties, including:
Testing and Compliance Compliance is determined via referenced ASTM test methods, such as:
Sampling and Packaging Material sampling must follow ASTM D140/D140M. Containers must be marked with the manufacturer, ASTM designation, flash point, and application temperature.
SEBS-modified mopping asphalt offers significant advantages for roofing professionals and manufacturers. Its practical applications include:

These attributes make SEBS-modified asphalt particularly suitable for both new construction and roof renovations where superior durability, flexibility, and consistent physical properties are required in diverse climates.
To ensure full compliance and performance in roofing applications, ASTM D6152/D6152M-12(2024) references several related standards:
Compliance with ASTM D6152/D6152M-12(2024) assures that SEBS-modified mopping asphalt products meet internationally recognized standards for quality, consistency, and performance. It facilitates specification, procurement, and inspection processes for contractors, manufacturers, specifiers, and building owners committed to long-lasting, high-performance roofing systems.
