The Harare City Council (HCC) has started patching potholes on link roads in the Zimbabwean capital using slurry seal as it moves to apply cheaper methods of maintaining thoroughfares, most of which have become impassable.

A slurry seal is the application of a mixture of water, bitumen emulsion, aggregate (very small crushed rock) and additives to an existing bitumen pavement surface. Slurry seals are generally used on residential streets and it is applied in order to help preserve, protect the underlying pavement structure and provide a new driving surface.

Roads chosen for slurry seal applications generally have low to moderate distress and narrow crack width. Once applied, slurry seals need four to six hours to set or harden before being opened for traffic.

Harare City Council spokesman Michael Chideme confirmed Monday that the city had started using a new material which looked like cement for patching up of potholes along the Kambuzuma Road.

"It is called slurry seal and it is going to be used in other locations," he said.

Most local authorities have been failing to repair roads leaving motorists to navigate the treacherous terrain, which damages vehicle suspensions and tires, sometimes causing accidents.
