Abstract:
In August 2017 GIBB (Pty) Ltd was
requested by Exxaro Coal Mpumalanga
to conduct a detail design in order to
upgrade one of their existing gravel access
roads to surface standard at Matla Mine
in Kriel, Mpumalanga.
The road is a 1.8 km gravel road that
provides access from provincial road R580
to the Matla coal stockpile. This road
needed to be upgraded to surface standard
in order to accommodate 600 coal trucks
per day. Results from laboratory testing
showed that the pavement consisted of a
G10 subgrade below a 200 mm thick G6
layer which was constructed as part of the
mine’s maintenance efforts over the years.
