The MHCA and industry representatives have scheduled two meetings with Public Works this month to review both the experience with recycled concrete aggregates, and base and sub-base materials in general, using the new City of Winnipeg roadbuilding specifications.
The first meeting, November 18, will deal specifically with recycled concrete, which remains a pressing issue. This summer’s construction season saw no recycled concrete used in roadbuilding, as suppliers struggled to consistently meet the new specs for sub-base and base materials.
The full Specification Review Committee, which includes representatives from MHCA, Urban Development Institute and ACEC- Mb, will meet November 26 to review generally the experience with the R21 specifications for roadbuilding.
“There remains a great deal of work to ensure that recycled concrete aggregates can be used in a meaningful way for city roadbuilding projects,” MHCA President Chris Lorenc said “These meetings are critical for industry and Public Works, to move toward agreement so we can fulfil the direction from the IRPW Committee of Council to find a way to increase the use of recycled aggregates.”
