New Specification for Geotextile Separation, Drainage & Bond Breaker Interlayer

1. Scope

2.1 The scope of the Committee shall be the formulation of test methods, specifications, guides, practices, terminology, and the dissemination of knowledge dealing with geosynthetics. This would include but not be limited to geotextiles, geogrids, drainage nets, drainage composites, geosynthetic clay liners, geosynthetic erosion control products and sediment retention devices, geosynthetic strips, geofoam and geomembranes.
2.2. The formulation of test methods, specifications, guides, practices and terminology for Geosynthetic related products shall be considered by the Committee by establishment of special subcommittees approved by the Executive Subcommittee.
2.3 The work of this Committee will be coordinated with other ASTM committees or organizations having mutual interest.


geotextile bond breaker, concrete pavement, concrete overlay, unbonded overlay


Since the May 2009 FHWA scan tour publication on geotextile bond breakers, there has been significant advancement in the approval, acceptance and specification for DOT and local projects and no advancement of an AASHTO specification. The use of geotextile bond breakers is growing worldwide. New developments in research have led to improved specifications and installation guidance. One improved installation method uses adhesive to fasten the geotextile to existing concrete pavement over a traditional nail down method. Providing the industry with an updated specification will aid in continued DOT, local and private projects and can be used worldwide. This specification will be used in the design and construction of new concrete pavement over cement treated base, lean concrete base or cement stabilized soils, unbonded concrete pavement overlays and possibly concrete overlays over existing composite pavement. DOTs, local agencies, private developers, engineers and contractors will use this specification.

The title and scope are in draft form and are under development within this ASTM Committee.
