The Department continually monitors the condition
of roads throughout the province for the purpose of
planning, maintenance and reconstruction. In 2006,
approximately 60 % of the paved road network was
measured by “road roughness testing”, dynamic
cone penetration (DCP) and evaluation of skid resistance.
The Departmental technical centre also conducted research
with a view to locating mapping and evaluating material
sources for road building in the province. A number of
material sources have been tested for suitability.
The Department continues to use the bridge management
software programme developed by the CSIR to manage 1,610
bridges and 2,008 culverts in the province. In 2006
a visual inspection of 323 bridges and 267 culverts was
The department uses the Road Management System (RMS) to
provide a scientific basis for evaluating the condition of
paved and unpaved road networks. Pavement Management
Systems (PMS) and Gravel Road Management Systems (GRMS)
are also used.
