Standard Specification for Hybrid Geosynthetic Paving Mat for Highway Applications
SCOPE
1.1 This is a material specification covering hybrid geosynthetic paving mats typically used for, but not limited to, use in joint and localized (spot) pavement repairs; and paving mats intended for curb-to-curb coverage to provide a moisture barrier for the pavement structure and retard reflective cracking in bituminous overlays. They are typically nonwoven in construction. This is a material purchasing specification, and design review of use is recommended.
1.2 This is not a construction or design specification. This specification is based on hybrid geosynthetic paving mat survivability from installation stresses.
1.3 For purposes of determining conformance to this specification, values for length or area shall be rounded to the nearest 0.1 m or 0.1 m2, respectively. Values for mass shall be rounded to the nearest gram, and for force to the nearest Newton, and volume to the nearest 0.01 L, in accordance with the rounding method in Practice E29.
1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the standard.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of 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.
1.7 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.

Overview
ASTM D7239-13(2023) is the internationally recognized standard specification for hybrid geosynthetic paving mats used in highway applications. This specification provides requirements for hybrid geosynthetic paving mats primarily applied for joint and spot pavement repairs, as well as curb-to-curb coverage to serve as a moisture barrier and to mitigate reflective cracking in bituminous overlays. Developed by ASTM International and aligned with World Trade Organization (WTO) principles, this standard helps ensure the quality and effectiveness of paving mats for infrastructure projects worldwide. The scope of ASTM D7239-13(2023) covers material characteristics and survivability under installation stresses but does not address construction or design practices.
Key Topics
- Material Specification: Defines hybrid geosynthetic paving mats, typically nonwoven and constructed from primarily inorganic fibers, sometimes blended with organic materials. These mats must withstand installation stresses and maintain integrity under various conditions.
- Types and Classification: The standard covers five main types (Type I, IIx, IIy, III, IV) of hybrid geosynthetic paving mats, differing in structure and reinforcement orientation to address specific repair needs and performance requirements.
- Physical Properties: Parameters such as breaking strength, elongation, mass per unit area, asphalt retention, and melting point (205°C minimum) are specified to verify performance.
- Manufacturing and Quality Control: Establishes requirements for the consistency of materials, dimensions, labeling, packaging, and the maintenance of quality control programs by manufacturers.
- Testing and Certification: Outlines procedures for sampling, testing methods, and minimum average roll values (MARV) to confirm conformance, as well as requirements for manufacturer certificates to accompany each order.
Applications
Hybrid geosynthetic paving mats manufactured according to ASTM D7239-13(2023) are essential in various pavement maintenance and rehabilitation scenarios, including:
- Joint and Localized Pavement Repairs: Used in spot repairs of bituminous or portland cement concrete surfaces to restore pavement integrity cost-effectively.
- Full-width Paving Applications: Provide curb-to-curb moisture barriers to protect the underlying pavement structure from water infiltration, which contributes to long-term durability.
- Reflective Crack Mitigation: Help retard the propagation of reflective cracking in bituminous overlays, improving the service life of overlay installations.
- Compatibility with Hot Mix Asphalt: Suitable for installation with hot mix asphalt concrete, meeting the demanding requirements of modern roadway construction and resurfacing.
For asset owners, designers, and contractors, employing ASTM D7239-13(2023) paving mats enhances infrastructure resilience, lowers lifecycle costs, and contributes to more reliable highway performance.
