ASTM D8173-23

Standard Guide for Site Preparation, Layout, Installation, and Hydration of Geosynthetic Cementitious Composite Mats

SIGNIFICANCE AND USE
4.1 This guide identifies proper layout, installation, and hydration procedures along with equipment for use by GCCM designers, inspectors, and installers.  
4.2 Applications—Typical GCCM applications may include but are not limited to:  
4.2.1 Hydraulic structure armoring or protection, including but not limited to: ditches, swales, canals, flumes, and other similar structures.  
4.2.2 Slope protection.  
4.2.3 Berm and bund lining and protection.  
4.2.4 Culvert invert lining.  
4.2.5 Scour protection at culvert inlets and outlets.  
4.2.6 Remediation of existing concrete channels and structures.  
4.2.7 Lining of outfalls and spillways.  
4.2.8 Mow strips or weed suppression.  
4.2.9 Lagoons and secondary containment berms (using GCCBs).
SCOPE
1.1 This guide covers directions for the installation of geosynthetic cementitious composite mat (GCCM) materials under field conditions typically present in erosion control, hydraulic structure armoring and protection, and protection applications. This guide also covers directions for the installation of a special category of GCCMs known as geosynthetic cementitious composite barrier (GCCB) materials, under field conditions typically present in geotechnical or civil engineering applications, with the purpose of reducing or preventing the flow of fluid through the construction.  
1.2 The values in SI units are to be regarded as the standard. Values in inch-pound units are in parentheses for information.  
1.3 This guide contains general guidelines. It is not intended to replace project-specific installation requirements. In the event of a conflict between the two, the requirements of the project specifications will supersede the requirements of this guide.  
1.4 This is not an all-inclusive guide, and some projects will be beyond the scope of this guide.  
1.5 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.  
1.6 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.
