From July 10-14,APAC Shears of Salina will complete the City of Salina’s annual ultrathin bonded asphalt surface project. The schedule is as follows, weather permitting:

Salina APAC Shears
Salina APAC Shears

Motorists are urged to avoid work zones altogether or proceed with caution for the safety of the crews performing the work.

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 lifespan (8-10 years) than micro-surfacing (6-7 years).

The $759,000 project is a major part of the City of Salina’s $4.7 million 2023 maintenance capital improvement program.
