SPS is milling and paving nightly with Brox Industries, Inc. in the central artery tunnel of Boston. The work window is typically 4 hours nightly and all of the milled Microsilica wearing surface is replaced with new pavement on a nightly basis. We’re expecting to have a few thousand tons of pavement installed by the end of this year. Men in safety vests watching paving happen. Men in safety vests watching paving happen.
