Abstract: The purpose of this study is the evaluation of effect of water and emulsion contents in microsurfacing mixture design. Micorsurfacing method which is one of pavement preservation technologies is currently used in Korea. Hot-mix asphalt(HMA) overlay is generally used for pavement preservation treatment in Korea. Microsurfacing treatment was commonly used for pavement preservation and maintenance in the world. Microsurfacing consists of a mixture of polymer-modified asphalt emulsion, aggregate, mineral filler, water and other additive. As changed contents of water and emulsion, the performance of microsurfacing would be changed. Excessive water and emulsion content may cause the mix to segregate and leave a flushed or excessively smooth surface texture or less adhesion. To determinate a wearing qualities of microsurfacing system under wet abrasion conditions, wet track abrasion test was adopted in this study. Also, Cohesion test was conducted to determine the cohesion build-up in a micro

Abstract: Road development in Taiwan has progressed to the maintenance and management stages of its life cycle. Therefore, it is necessary to introduce information technology approaches to assist in pavement management activities. Belief-function theory (BFT), otherwise known as the Dempster-Shafer theory of evidence, has been advocated by many as a method of representing uncertain, incomplete, and imprecise evidence of a system’s knowledge base. BFT is still scarce in applications for the construction industry and even pavement management until now. This paper applied BFT to pavement management, in particular to the pavement maintenance and rehabilitation (M and R) activities. One case study was conducted using BFT to understand whether M and R activities need to be implemented for a pavement section. This study completed a preliminary study of BFT to promote efficiency in pavement management.
