A newly approved standard from ASTM International’s recovered carbon black committee ( D36 ) provides a test that will help to differentiate products and provide a quality control tool for producers and users. Recovered carbon black (rCB) is a recycled product made from end-of-life tires. The new standard (soon to be published as D8474) describes a thermogravimetric (TGA) technique to determine…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Melissa Marcinowski, tel +1.610.832.9626; mmarcinowski@astm.org Release #11602 ###

ASTM International’s recovered carbon black (rCB) committee ( D36 ) is developing a proposed standard that will be used to differentiate between different rCB products and provide quality control tool for producers and users. According to ASTM International member Pieter ter Haar, the proposed standard ( WK81244 ) will explain how thermogravimetry (TGA), a type of thermal analysis, can be used to…

ASTM International’s geosynthetics committee ( D35 ) has approved a new standard that will help engineers, designers, and specifiers who work with vinyl sheet piling. Applications for such piling include the construction of seawalls, retaining walls, and chemical cut-off walls. “The new specification will standardize the materials used and it will allow producers to meet the United States Army…

ASTM International’s geosynthetics committee ( D35 ) is developing a proposed standard that will help provide engineers with specific information for components necessary for road and pavement design. The proposed standard ( WK70888 ) outlines a commonly used test to characterize the performance of geosynthetics for roadway applications. Specifically, it describes the use of the cyclic plate load…

ASTM International’s geosynthetics committee ( D35 ) is developing a proposed standard that covers vinyl sheet piling used in marine and geotechnical fields for seawalls, retaining walls, flood walls, erosion control, and pollution cut-off. According to ASTM member Steve Hargrave, the proposed standard ( WK75165 ) will fill the need for a specification for vinyl sheet piling used for structural…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org , Committee Contact:, Travis Murdock, tel +1.610.832.9826; tmurdock@astm.org Release #11185 ###

A new ASTM International standard aid engineers and specifiers looking to understand the quality and strength of cement contained in geosynthetic cementitious composite mats (GCCMs). ASTM’s geosynthetics committee developed the new standard, which is needed to allow for a consistent industry method for the application of compression strength in GCCMs. GCCMs are flexible concrete impregnated…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11045 ###

A proposed ASTM International standard will provide guidance for using geocells – open-celled geosynthetics that help hold soils and rocks in place – in roadway projects. Geocells are commonly used in road construction, earth retention, and other construction projects. According to ASTM International member Eli Cuelho, there is currently no standard for using geocells in geotechnical and…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #10955

ASTM International’s committee on recovered carbon black ( D36 ), formed in 2017, has approved its first standard. The new standard ( D8178 ) defines important terms in the recovered carbon black (rCB) industry. ASTM International member Bill Cole notes that recovered carbon black is a relatively new, sustainable raw material product, produced by a new and growing industry, for use in rubber,…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Joe Koury, tel +1.610.832.9804; jkoury@astm.org Release #10748

A new ASTM International standard will help those who construct and install geosynthetic clay liners (GCLs), which are used to help with containment for: landfills; coal combustion residual storage cells; mining operations; and, remediation and environmental protection projects. The new standard ( D8204 ) focuses on evaluating both best practices as well as possible negative impacts of installing…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #10612

A new ASTM International standard supports geosynthetic cementitious composite mats (GCCM), a new family of materials that can help control erosion, protect slopes and berms, and line ditches and culverts. The new standard ( D8173 ) identifies proper layout, installation and hydration procedures for GCCM. It also describes equipment for designers, inspectors, and installers as well as provides a…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #10513
