Per our traffic and public safety reporter, Cordell Pugh, the Wheaton Bus Loop has reinforced concrete pavement instead of asphalt. Project may also include replacing the reinforcing steel (“rebar”) and/or an entirely new subbase (graded and compacted base layer [usually gravel] under the concrete). Concrete work does take longer than asphalt resurfacing. When installed correctly, however, concrete outperforms asphalt pavement, especially under enhanced stress from continuous presence of heavy vehicles (buses etc).
