On Monday through October 12, APAC-Kansas, Inc., Shears Division of Salina will perform the ultrathin bonded asphalt surface (UBAS) maintenance on the following streets for the City of Salina, weather permitting. This type of preventative maintenance is fairly new to Salina but has been used to help extend the life of many roads around the State of Kansas. It consists of a thin, coarse aggregate hot mix over a special asphalt membrane similar to a chip seal but placed in one pass with a spray paver. The membrane prevents water intrusion and provides a superior bond to the old asphalt. The overlay can disperse water quickly off the surface, which reduces roadway spray from vehicles and provides greater visibility and traction in wet weather. UBAS has performed well for other cities and provides a good friction surface in wet weather. UBAS can be installed quickly, and asserts a longer life-span (8-10 years) than micro-surfacing (6-7 years).
