Sustainable pavement construction: Use of non-potable water and smart techniques for compaction

Abstract

The western cape government reported an annual mean near-surface (2m) temperature (°C) change from the median and the 10% and 90% percentiles projected for 2036 – 2065 and 2066 – 2095. Across most of the country, model-simulated rainfall is slightly lower than observed, although the east-west gradient in rainfall is adequately represented. Autumn, which is the transition period between summer and winter, denotes slightly higher rainfall in the observed east and Western Cape region. Winter rainfall is higher in the Cape Town region in the observations, compared to the model simulations. The temperature and rainfall variations have a direct impact on the restriction of available potable water required. Due to the limited peer-reviewed research and use of non-potable water in road construction, this chapter will investigate preliminary laboratory research into the area as well as smart compaction techniques.
