The machine is mounted on a special truck with a powerful hose that sprays a mixture of cold bitumen and ballast into a pothole, sealing it at a fraction of the time it takes a conventional repair gang to do the job manually.
Kenya has been battling with the problem of potholes using traditional methods where a gang of up to five people dig around a pothole before filling it with hot bitumen and ballast, which are then compacted using road rollers.
The velocity machine does all this in one smooth operation, then moves on to the next pothole as traffic resumes its path over the newly fixed road.
Velocity has appointed Avery East Africa (AEA), a subsidiary of TranCentury Ltd., as the sole distributor of its machines in East and Central Africa, as the UK firm seeks to tap into the demand for its products in the region.
Each machine, which is operated by two skilled workmen, is priced at Sh50 million – including the cost of personnel training.
The machine is divided into several storage spaces, including those for bitumen and ballast, which are mixed before being sprayed.
According to AEA chief executive Nicholus Kithinji, the technology has registered huge success in the road construction industry, especially in developed economies such as Europe.
“This kind of technology, that has been tested and proven, makes the job easy and allows traffic to flow easily after a short while. It is also cost effective,” said Mr Kithinji.
The high velocity technology is expected to cut costs of road repair by up to 40 per cent, offering reprieve to the national and county governments that are spending billions of shillings annually to fix roads.
Kenya has now become the second African country to adopt the new technology after South Africa.
