Manufactured by Road Material Stabilisers (Pty) Ltd, it was originally developed in 2004 in response to a request from the Road Agency Limpopo’s Gundo Lashu project team which included representation from the International Labour Organisation and BKS Consulting Engineers. The brief was to design an asphalt seal to the highest possible recognised standards whilst maximising the labour component. A product was required that would be suitable for implementation and inclusion in poverty relief or EPWP programmes where contractors and their labour force have little or no prior experience and skills.
