The National Route 12 (classified as TR33/5) between Klaarstroom and Beaufort West in the Western Cape, South Africa, shows signs of deterioration evident through surface deformation, cracking, and disintegration. This deterioration potentially affects vehicle conditions, increases maintenance costs for motorists, and may lead to fatal incidents. This research study aims to develop a risk management approach to identify, evaluate, and manage different types of road distress on the TR33/5 road.

The study employs a mixed-methods approach using both qualitative and quantitative data from the Western Cape Provincial Government, including climate conditions, historical imagery, visual inspection reports, traffic volume data, and environmental factors. The research follows an integrated risk management approach aligned with ISO 31000:2018, incorporating quality tools such as Gap analysis, Ishikawa diagram, 5 Whys technique, and Failure Mode Effects Analysis (FMEA).

The research is currently in progress, with data collection and analysis underway. This paper outlines the methodological framework being implemented and discusses the expected contributions of the study. The implementation of the proposed risk management framework is anticipated to provide a systematic approach to identify, analyze, and prioritize road deterioration issues, enabling more effective maintenance strategies and resource allocation.

This ongoing research is expected to contribute to the development of a new approach to investigating and managing road defects on National Route 12, aimed at ensuring good quality road standards, reducing the risk of accidents, and lowering vehicle maintenance costs through proactive maintenance strategies.
