This update concerns the announcement from the provincial Department of Transportation and Woks on Wednesday, March 5 that the Bay d’Espoir Highway would receive some major upgrades in 2014.
A spokesperson for the department said that the work between km 80.6 and 86.6 would be pulverized and paved; the road between km 170.9 to 198.2 will be rehabilitated.
According to Department of Transportation terminology rehabilitation means increasing the roadway level of serviceability to a condition similar to new construction usually through such methods as overlays. Generally the condition of the pavement is such that preservation treatments are no longer cost-effective and such treatments can be more expensive. Drainage culverts, guide rails, signage, etc. should aloes be considered as part of rehabilitation.
Asphalt overlay means a new lift(s) placed on an existing pavement to restore the ride and safety, as well as strengthen the pavement’s structure.
Pulverize and pave means full depth reclamation of existing pavement and replacement with one or more asphalt pavement layers.
It should be noted that the km mentioned start from the Trans Canada Highway near Bishop’s Falls.
