摘要

The initial cost is a major deterrent in exploring advanced technologies, especially for developing countries. It is a common practice that researchers use life cycle cost analysis, considering direct and indirect costs, to justify the higher initial costs. However, when it comes to maintenance-related aspects, the direct cost numbers are significantly lower compared to initial construction and major rehabilitation costs. Hence, the increased costs of using advanced maintenance technologies need an additional cost analysis framework. The objective of the present study is to evaluate the economic viability of advanced pothole patching techniques for flexible pavements in developing countries using a framework that considers life cycle cost analysis and management principles. Two types of advanced pothole patching techniques, such as (i) application of heat energy to enhance the bond between the repair pavement surface and patching mix and (ii) the application of geogrid reinforcement to enhance rutting resistance of patching mixes, were explored. The research methodology includes quantification of the effectiveness of these advanced technologies in the laboratory and evaluating the economic viability using cost analysis principles. Laboratory performance tests, such as the Leutner shear bond and wheel rut tester, were employed to quantify the enhancement in bond and rutting resistance from using heat energy and geogrids for patching applications. The cost analysis aspects, such as life cycle cost of direct or agency costs, indirect or road user costs, break-even analysis, and financial implications at the state and national network level, were considered. The laboratory quantification of advanced patching techniques showed 39% increased shear strength between the repair surface and patch material when compared to conventional methods. The cost analysis confirmed the economic viability of these advanced techniques based on life cycle cost analysis and management principles such as break-even analysis. The framework used in this study would be beneficial for researchers and decision-makers in analysing any other advanced maintenance techniques along similar lines.
