Abstract: Knowledge of the fatigue characteristic of asphalt mixtures is essential for the design of flexible pavements since fatigue has been identified by researchers as one of the major failure mechanisms in flexible pavements. Information obtained from the laboratory fatigue characterization of such mixtures is normally used for predicting performance in service. While the literature is replete with information about the fatigue performance of hot asphalt mixtures (HMA), not much has been done to ascertain the responses of cold recycled asphalt mixtures which of late are increasingly becoming suitable and sustainable alternatives to HMA due to the energy, cost and environmental benefits they offer. This paper presents the results of laboratory fatigue characterization of cold recycled bituminous emulsion mixtures (CRBEMs) using the indirect tensile fatigue test (ITFT). The results showed among other things that cold recycled asphalt mixtures prepared at a mixing and compaction temperature of

Abstract: The international construction market is rapidly expanding again following the financial crises in Europe and the US, providing more opportunities for international construction firms to increase revenues from overseas projects. To advantage of these circumstances, most contractors seek opportunities to enter the growing overseas markets, particularly into the sector of infrastructure projects including high-speed railway and super long-span bridge. In the pursuit of this entry, these contractors must strategically decide which entry mode to use for a targeted market or project. In the present study, the entry mode for international projects is examined based on the following two questions: "Which factors should be considered to determine the entry mode?" and "How do these factors influence the entry mode?" To address these questions that are specifically tailored for super long-span bridge projects, “The five elements of strategy” are applied to develop a framework for contractors to
