THE GAUTENG DEPARTMENT OF ROADS AND TRANSPORT HAS COMMENCED
CRITICAL REPAIR WORKS ALONG THE N12 TO ADDRESS ROAD SURFACE DETERIORATION
CAUSED BY WATER INGRESS FROM UNDERGROUND CONCRETE PIPE INFRASTRUCTURE.
THE INTERVENTION FOLLOWS INVESTIGATIONS THAT IDENTIFIED WATER SEEPAGE
BENEATH THE ROADWAY, CONTRIBUTING TO PAVEMENT DISTRESS AND THE
FORMATION OF POTHOLES. THE REPAIR WORKS ARE AIMED AT RESTORING THE
STRUCTURAL INTEGRITY OF THE ROAD, IMPROVING DRAINAGE AND ENSURING THE
CONTINUED SAFETY OF MOTORISTS.
AS PART OF THE REHABILITATION PROCESS, TRAFFIC MANAGEMENT MEASURES HAVE
BEEN IMPLEMENTED IN ACCORDANCE WITH APPROVED SAFETY STANDARDS. THESE
INCLUDE THE PLACEMENT OF ROAD WARNING SIGNS, BARRIERS, DELINEATORS AND
CONES, WHILE TRAINED FLAG PERSONNEL ARE ASSISTING WITH TRAFFIC FLOW IN
AFFECTED AREAS. MOTORISTS ARE ADVISED TO EXERCISE CAUTION AND ADHERE TO
ALL TEMPORARY TRAFFIC CONTROL MEASURES.
THE SCOPE OF WORK INCLUDES THE EXCAVATION OF THE AFFECTED SECTION TO
EXPOSE AND ASSESS THE CONDITION OF CONCRETE PIPES CROSSING BENEATH THE
HIGHWAY. ENGINEERS WILL INVESTIGATE THE SOURCE OF WATER INGRESS, INSPECT
PIPE JOINTS AND STRUCTURAL ELEMENTS, AND UNDERTAKE THE NECESSARY REPAIRS.
THE AFFECTED PIPE INFRASTRUCTURE WILL BE SEALED AND REINFORCED WITH READY-
MIX CONCRETE AND STEEL MESH TO PREVENT FUTURE LEAKAGE.
TO STRENGTHEN THE ROAD FOUNDATION, THE EXCAVATION AREA WILL BE
RECONSTRUCTED USING STABILISED LAYERWORKS, INCLUDING THE PLACEMENT OF
DUMPROCK, GEOTEXTILE MATERIAL, AND COMPACTED G7 AND G5 SUB-BASE
LAYERS. ONCE THE STRUCTURAL LAYERS HAVE BEEN REINSTATED, A BITUMEN-
TREATED BASE AND ASPHALT SURFACING WILL BE APPLIED TO RESTORE THE ROADWAY.QUALITY ASSURANCE MEASURES, INCLUDING COMPACTION AND DENSITY TESTING,
WILL BE CONDUCTED THROUGHOUT THE PROJECT TO ENSURE COMPLIANCE WITH
ENGINEERING STANDARDS. THE REPAIRED SECTION WILL ONLY BE REOPENED TO
TRAFFIC ONCE ALL WORKS HAVE BEEN COMPLETED AND CERTIFIED AS SAFE.
THE DEPARTMENT REMAINS COMMITTED TO MAINTAINING AND IMPROVING
GAUTENG’S ROAD NETWORK WHILE PRIORITISING THE SAFETY OF ROAD USERS AND
CONSTRUCTION PERSONNEL. THE DEPARTMENT APOLOGISE FOR ANY INCONVENIENCE
CAUSED DURING THE REPAIR PERIOD AND THANK MOTORISTS FOR THEIR PATIENCE AND
COOPERATION.
