City authorities and roadways agencies in winter regions impose restrictions on neighborhood roadway construction activities based on severity of weather. The limitations are imposed mainly to avoid inadequate compaction of asphalt that results in poor performance of roads. Weather fluctuations during late fall season cause delay in work and extend project schedule. As a result, significant increase in development cost is observed due to long-term project overhead and idle equipment costs. In the construction industry, there are examples of successful paving works at severe weather using innovative technologies and materials. However, the construction professionals have to take decision based on the cost benefit analysis of these two options: i) select any of these technologies to avoid schedule extension, ii) wait for the allowable weather. This paper attempts a study of the weather limitations on the asphalt paving works, demonstrating its application to a neighborhood road construction project in Greater Edmonton, Alberta, Canada. It proposes a framework to quantify the impact of these limitations by using the historic weather data and developing a simulation model of paving work to analyze the change of construction schedule while ensuring the asphalt performance in severe weather. The outcome of this study can be used to develop a model for cost benefit analysis of a neighborhood development work.
