Life cycle cost comparison of highways with perpetual and conventional pavements

Evaluation of Application of Thin HMA Overlay on the Existing Flexible Pavement for High-Traffic-Volume Rural Highways

“…These performance indicators consist of IRI, rut depth, and fatigue cracking. Because high-traffic-volume roadways are considered in this study, amount of thresholds considered for these performance indicators are 2 m/km, 10 mm, and 20% respectively by assuming 95% reliability as reported by Amini et al [16]. Table 10 shows the amount of thin HMA overlay service lives obtained for these climatic conditions.…”

“…Also, this software has been used to evaluate the performance of flexible pavements; e.g., Amini et al [16] used MEPDG and highway development and management 4 (HDM-4) to compute life cycle cost of conventional and perpetual pavement sections over a period of 40 years.…”

A Comprehensive Life-Cycle Cost Analysis Approach Developed for Steel Bridge Deck Pavement Schemes

“…Life-cycle economic analysis is a method of economic budgeting and comparison during the life-cycle from engineering construction to demolition. The basic idea of life-cycle economic analysis is to consider not only the initial construction cost but also the maintenance cost, residual value, user cost (mainly including fuel consumption cost, wheel consumption cost, warranty cost, and accident cost), and other costs that should be taken into consideration during the service period [11,12]. At present, a relatively mature life-cycle economy analysis framework for road pavement schemes has been formed, and a life-cycle economic analysis of pavement structure has been applied to research into road pavement scheme comparison and selection, maintenance decision-making, limited capital allocation, and so on [13][14][15][16].…”

A Framework for Economic Evaluation of Highway Development Projects Based on Network-Level Life Cycle Cost Analysis

“…Amini et al compared LCC of highways with conventional and perpetual pavements. Mechanistic-Empirical Pavement Design Guide (MEPDG) model is used for the prediction of pavement performance and HDM-4 model is used for the selection of optimum M&R practices, [10]. Goedecke et al carried out a study on the effect of alternative fuels and vehicles on LCCA of a highway facility.…”

“…So, vehicle operation costs, passenger and cargo time-related costs and accident costs may alter and previous LCC estimations will be no longer valid. Generally, an analysis period of 20 years is chosen for traffic forecasts, 20 to 40 years for pavements and 75 years or more for infrastructures such as bridges and buildings, [10,21]. For a highway network, a life cycle of 10 -50 years can be selected based on highway agency needs and visions.…”
