Online PR News – 26-July-2016 – Pretoria – Bakwena, the concessionaire of the N1N4 toll routes, has commenced with maintenance on the N4 west from the M17 Garankuwa interchange to the R512 Brits interchange.
“The section of the road being resurfaced was constructed in 2003 and, since then, it has been maintained according to international and local road safety standards. However, 13 years on, the road is showing signs of wear and tear which is why more intensive maintenance is required,” explains Bakwena's Commercial Manager, Liam Clarke. “While we understand that road maintenance is never convenient for the road user, it is important to reiterate that if this is not done, the road structure will become damaged, leading to more severe deterioration and what would be a more costly rehabilitation or reconstruction process later on. This would mean longer reconstruction times and extended delays for road users.”
Clarke adds that the road resurfacing procedure will be twofold. First, a slurry will be placed over the existing surfacing as a texture corrector. This will need to set before vehicles can use it, or it will drive off, sticking to tyres and causing damage to vehicle paintwork.
Once the slurry is cured, a double seal will be placed over it. This seal consists of a first layer of bitumen and a
layer of larger stones, followed by a second layer of bitumen and a layer of smaller stones. Finally, a third layer of bitumen will be applied - to ensure to the stone remains intact before the road can be opened to traffic. Again, if roads are opened too soon, vehicle and surface damage may ensue.
As this section of the road is predominantly a single carriageway, stop-go’s are the only cost- and time-effective way to manage traffic. As per road maintenance regulations, there will only be 2km closures on the working section with a minimum distance of 4km between working areas.
“Bakwena will do everything in our power to ensure that delays are kept to a minimum, however, as this section is heavily trafficked, delays of up to 20 minutes can be expected Monday to Thursday from 8.30am to 4pm, Fridays from 8.30am to 2pm and Saturdays from 8:00am to 4pm,” concludes Clarke. “We appeal to road users to please bear with us during the maintenance period as we strive to achieve a road surface that is safe and resilient, and adheres to Bakwena’s high standards.”
