Deterministic and stochastic life-cycle cost analysis for Otta seal surface treatment on low volume roads
Abstract The US has a considerable length of unpaved secondary roads experiencing relatively low daily traffic volume. To maintain such roads, the US county secondary road departments spend millions of funds annually for aggregate replacement alone. Meanwhile, Otta seal has been reported as a low-cost bituminous surface treatment (BST) and dust mitigation technique. In consideration of its limited use in the US, Otta seal could be compared with chip seal, which is a commonly used BST in the US, from an economic viability perspective. In this study, through using the Minnesota case, a life-cycle cost analysis was conducted at two levels: (I) deterministic life-cycle cost analysis and (II) stochastic life-cycle cost analysis. Based on the analysis results, it was concluded that the Otta seal could potentially be an economic viable BST, and public agencies could use it to reduce maintenance cost of low-volume roads, especially when gaining access to uniformly graded aggregate, which is commonly not feasible for chip seal.
