Candle Wax (CW) and Fatigue Performance

Performance analysis of flexible pavement wearing course subjected to submergence was carried out. The goal of this study is to improve the performance of the wearing course in terms of fatigue using candle wax as a waterproofing agent. In Nigeria especially in the Niger Delta area, flooding is common during raining season. Pavements are observed to be underwater continuously causing rapid failure. Founded on this, the recent study was aimed at evaluating the fatigue performance of flexible pavement wearing course using candle wax modified asphalt pavements in soaked conditions. This was accomplished by first modifying the asphalt concrete at 1%, 2%, 3%, 4% and 5% and submerged in water for 0 day to 5 days. The results obtained have shown that fatigue performance can be improved at 4% modification using candle wax. The finding has proven that candle wax is a waterproofing agent.
