Gravel loss on unsealed roads is a major financial setback for all road agencies. It is also environmentally unsustainable to continue forever with continual gravel loss. Unsealed road management issues include difficulty in forecasting behavior, significant data collection needs, and vulnerability in level-of-service and maintenance practices. Quality of gravel material is one of the greatest influencing factors. All over the world and in Australia–New Zealand various studies have been completed and gravel loss models have been developed to estimate gravel loss. Those studies have developed gravel loss models and deterioration model and maintenance strategy. Some of the studies have used a different approach such as the system dynamic modeling approach, which can be grouped under the asset management approach. This literature review summarizes various approaches related to gravel loss and briefly provides the available opportunities for further research.
