Zimbabwe roads are now a death trap

Structural maintenance, repair and rehabilitation

Roads are exposed to tremendous loads that will sooner or later leave their marks on them. A time will come when every road will be in need of a general overhaul. But no two damage patterns are alike.

Which rehabilitation methods offer a cure for distressed roads? What are the differences between them? Which are suitable to be carried out as mobile roadworks?

Replacing the pavement

Replacing the pavement is one of the standard methods in road rehabilitation. What are the challenges posed by this rehabilitation method? What machines are used for replacing the road pavement? What are the methods used for building a new pavement?

Replacing the pavement is a standard procedure when repairing roads. The challenge is to ensure that only the damaged layers of the road structure are removed - and to avoid disruptions to traffic at the same time. Under these conditions, cold milling is the only viable option for many construction projects. The roads that were left by the Smith regime in 1980 have now gone beyond repair because of the failer of the Zanu government.
