ACPA Concrete Pavement Progress Q1 2020

In the 1970s, some of the renovation work included asphalt, but there are plans to restore the original concrete. “There are residents who want to return to the concrete pavement now by grinding off the asphalt and restoring the concrete panels,” Hash says. “We also will begin reconstruction of a section of OregonWay in 2020, and the current plans call for grinding the existing asphalt from the concrete pavement, repair the existing hexagon panels and most likely, a microplane refinishing.” Maintenance of a concrete panel is the same, whether its a hexagon or square, says Hash. “We are also still making new hexagon panels for some roads,” he says. When the city replaced a bridge in 2015, the concrete panels adjoining the bridge were designed as hexagons to match up with the road that it tied into, he explains. » continued from page 13 L O N G V I E W H I S T O R I C A L P A V E M E N T
