The employer’s objectives of this case study was to upgrade gravel roads in the Brandwag Community to surfaced standard, with preference to Ultra-Thin Reinforced Concrete Pavement, constructed by means of labour intensive construction methods to maximise the use of local labour.
From the onset it was clear that the design and documentation needed to be adapted in order to maximise the interest of the community as well as ensuring a quality product. Well balanced use of equipment and local labour was vital to the success of the project as extensive training was done before the specific tasks were programmed to commence.
On-site design changes were possible due to the flexibility of the “Spin Screed” being used, with resultant innovative techniques that result both in time saving as well as improved constructability and quality. Quality control of both virgin and modified materials before, during and after construction needs a higher level of supervision, which must not be underestimated.
A direct cost comparison was possible to conventional methods as this was part of the project scope. Crucial to the success and sustainability of this method, however, is long-term commitment from authorities, with guaranteed financial and technical support.
