www.acpa.org Quarter 3, 2020 A C P A N E W S 27 THE US DOT ANNOUNCED RECENTLY that the Trump Administration will award more than $273 million in air- port safety and infrastructure grants through the FAA. “This $273 million federal investment in our nation’s airports will strengthen safety, improve travel, generate jobs, and benefit local communities,” says US DOT Secretary Elaine L. Chao. The grants will go to 41 states, the District of Columbia, American Samoa, the Feder- ated States of Micronesia, the Marshall Islands, Palau, and Puerto Rico. A complete listing of grants ( and an interactive map of airports receiving funding is available on the FAA website. The funding amount includes more than $242 million in AIP funds and $31 mil- lion in Coronavirus Aid, Relief, and Economic Security (CARES) Act grants. The grants will be used for critical infrastructure and safety projects, including constructing and repairing runways and taxiways. The funds will also be used for other purposes, including airport master plan studies, installing aircraft lighting and signage, other safety and security measures. US DOT Announces Airport Grants IGGA, AN ACPA TECHNOLOGY PARTNER, has released an updated guide specifica- tion for the Next Generation Concrete Surface (NGCS). Visit the link below to download the guide spec, “NGCS Construction on Existing or Newly Constructed Roadways,” from the IGGA website. Revisions to the guide spec, specifically narrowing the blade settings, were made to further reduce the “skittering” or lateral stability concerns, says Larry Scofield. Scofield says California developed longitudinal grooving in the 1960s and constructed more than anyone else at that time and since. During its early deployment, they evaluated a number of things including groove width. Initial research showed the 0.095 in. blades produced less “skittering,” so since the late 1960s, California has required these narrower blades. He adds this is the first change that has been made to NGCS since the proof of testing.
