PROJECT OVERVIEW
Public Highways Access Road to IDB Hobhole Pumping Station had deteriorated and becoming dangerous for delivery truck and the like due to subsidence to one side. The shoulders of the road needed to be reinforced before any surfacing could be done. Simply overlaying and filling the depressed area was not an option as previously done.
JJMac offered a solution to in-situ stabilise the shoulders and to recycle the existing road material.
