A relatively short highway construction season exists on the Canadian Prairies and typically the paving season extends from May to October. Highway engineers and contractors are continually confronted with unfavorable weather conditions during the early spring and latter parts of the fall paving season. During these periods of cooler weather, the decision as to whether or not to allow paving to continue or begin becomes very difficult, since freshly laid pavements cool quickly and proper compaction is difficult to attain. The final density obtained in a pavement depends critically on its initial temperature and cooling rate. This study researches the subject of pavement cooling and investigates the feasibility of cold-weather paving. The results of this study illustrate the significance of the factors affecting pavement cooling and provide information for improving the paving specifications used by Sasketchewan Highways and Transportation. This study also shows that the short paving season which exists in Sasketchewan can be extended under certain conditions. Extension of the construction season into colder weather will provide financial and various other benefits, not only to Sasketchewan Highways and Transportation but also to paving contractors and the general public.
