Abstract

Previous work has shown that current specifications do not always correctly identify the weather conditions that are unsuitable for laying and compacting rolled asphalt wearing course materials. Using data from the Meteorological Office for nine airfield sites, it is shown that the weather conditions in the UK can be considered adverse for over 90% of the time for compacting a 40mm thick rolled asphalt mat. On the other hand, the weather is rarely unsuitable for laying a 50mm mat. Models are developed for predicting the probability of the weather being adverse for sites at given latitude and altitude by month and time of day.
