ASTM International’s unmanned aircraft systems (UAS) committee ( F38 ) has approved a new subcommittee on infrastructure. The mission of the new subcommittee (F38.04) is to identify, evaluate, and establish best practices for the design, construction, and maintenance of UAS infrastructure. This included landing and takeoff zones, charging and refueling stations, and date communications systems. "…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11696 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard ( WK73384 ) that will evaluate the tensile performance of fiber-reinforced concrete using cylindrical specimens with double-punch loading. The proposed standard contains “pre- and post-peak tensile properties (that) hold great significance in fiber-reinforced concrete (FRC) and ultra-high-…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11676 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard specification for a broad range of supplementary cementitious materials (SCMs). According to ASTM International member Larry Sutter, this performance specification ( WK70466 ) will ease the adoption of new materials used for SCMs as established sources become less available. “For a variety of…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11659 ###

ASTM International’s unmanned aircraft systems committee ( F38 ) is developing a proposed standard that will help identify communications security principles and relevant frameworks for securing ad hoc uncrewed aircraft system communications. ASTM member Drew Van Duren says that the proposed standard ( WK84631 ) will identify and describe a tailorable approach to securing aircraft-to-anything (…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11625 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard that will be used to help measure the tensile strength of fiber reinforced concrete. According to ASTM International member Luke Pinkerton, the use of fiber reinforcement as an alternative to conventional reinforcement of various concrete structures has been limited in the construction…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11599 ###

A new ASTM International standard supports the design of civil vertiports and vertistops. The standard ( F3423 ) is the result of a five-year effort by ASTM’s unmanned aircraft systems committee ( F38 ). A vertiport is a section of land, water, or structure intended for either manned or unmanned vertical takeoff and landing of aircraft, along with the associated buildings and facilities. A…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11524 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a new standard for economical testing of concrete strength. The proposed standard, WK82351 , will provide a fast, simple, non-destructive method for testing concrete strength that can be performed almost anywhere. According to ASTM International member Neil Cox this method, which measures the dominant resonant…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11488 ###

A new ASTM International standard ( F3548 ) will be used to satisfy requirements that are expected to be common for traffic management of uncrewed aircraft systems (UAS), commonly referred to as drones. The flight operations subcommittee of ASTM’s unmanned aircraft committee ( F38 ) developed the new standard on UAS traffic management (UTM) with input garnered across multiple continents and a…

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…
