Recent activity concentrates in Texas, Illinois, Georgia, Maine, California, Wisconsin, and Florida, with secondary activity in New York, New Jersey, and other states. Representative highway and pavement maintenance opportunities include Collin County's asphalt and aggregate procurement (IFB 2026-277 through 2026-280, due July 16, 2026) for road materials and surface treatments; Santa Clara County's expressway guardrail and pavement rehabilitation projects (ITB-RDA-FY26-0652 and ITB-RDA-FY26-0559, due April 23 and March 5, 2026 respectively); and airfield rehabilitation work at Hartsfield-Jackson Atlanta (PE66062NONST2026000000347, due April 30, 2026) requiring full-depth runway reconstruction and taxiway rehabilitation with joint sealing as a critical subcontractor scope. County and municipal pavement maintenance contracts dominate the pipeline—Dane County Wisconsin (RFB 2026RFB006 and RFB17A26041300000000000259 for hot pour and no-box sealants), Brevard County Florida (Bid B-2-26-08 for pavement maintenance services), and Barrow County Georgia (PE77075NONST2026000000014 and PE77075NONST2026000000015 for Wynn Lake Road resurfacing) show sustained demand. Airport and transportation infrastructure work—including taxiway rehabilitation at Okaloosa County Florida (ITB AP4926, due April 29, 2026), runway and apron sealing at Wayne County Georgia (PE75106NONST2026000000011, due April 9, 2026), and parking structure joint sealant replacement at Savannah Airport (SAC 30658, due March 31, 2026)—represents a secondary but consistent procurement stream where sealant materials command premium specifications and performance warranties.
