“…Upgrading to an Otta seal surface has been found in some cases to be necessary to save maintenance costs, improve road users’ safety, improve driving efficiency, decrease environmental pollution, and promote economic development in local areas. For instance, the lifecycle cost analysis (LCCA) of Nahvi et al ( 94 ) justified resurfacing gravel roads with an Otta seal for 15% of the gravel roads even without considering all the other benefits. The Republic of Lithuania considered implementing double Otta seal road surfacing to reduce the number of gravel roads to improve ride quality, vehicle delay costs, fuel consumption, maintenance costs, and negative environmental impact ( 45 ).…”

Gravel roads form a significant share of the global road network, usually in sparsely populated rural areas. They are important, especially in agriculture, tourism, and forestry, connecting rural to urban areas. This systematic literature study comprises 105 reviewed publications on gravel road maintenance. Review articles on maintenance management practices, especially concerning objective condition assessment and data-driven methods (DDMs), are lacking. Therefore, this review provides a concise overview of current gravel road maintenance practices and ongoing research on objective condition assessment and DDMs for gravel road maintenance. It offers researchers in gravel road maintenance and other related fields a clear indication of where to focus their research efforts, as it suggests the direction for future research. Visual assessment methods are predominant for monitoring the condition of gravel roads, while objective methods and DDMs are not common. Research on gravel roads and their maintenance has increased in the last two decades, especially in North America and Northern Europe. Condition assessment is shifting from subjective to objective methods, utilizing knowledge from technological advancements in image processing, vibration and acoustics analysis, and so forth. There are some excellent research initiatives for objectively assessing the condition of gravel roads and DDMs, but the practical implementation is limited. Implementing objective assessment methods and DDMs generally improves the management of gravel roads with regard to decision-making, maintenance costs, safety, and the stability and comfort of the ride. Objective condition assessment and DDMs have the potential to enhance maintenance practices in the maintenance of gravel roads.

“…Considering budgetary constraints, agencies need to use rigorous decision-making methodologies that provide insights about long-term economic viability. One of those methodologies is life cycle cost analysis (LCCA), which evaluates the economic burden while considering durability [7][8][9][10][11][12].…”
