“…The impact of water-exposed pavements was evaluated by immersing Marshall specimens under controlled conditions. The Marshall methodology has been widely used in previous studies for measuring flow and loss of stability in pavements [47][48][49][50]. The specimens were immersed into fresh water and sewage for 14 days.…”

This study evaluates the impact of exposing asphalt pavement to sewage and fresh water. In total, 87 samples were prepared, where half of them were immersed in sewage and the others were immersed in freshwater. The Marshall mix design method was adopted for the preparation of samples. Three immersed samples were tested for stability and flow every 24 hours in both fresh water and sewage, comparing the results with a control sample. The samples immersed in fresh water lost their stability and flow after 11 days, while the ones immersed in sewage water lost their stability and flow after 9 days. Furthermore, the loss in stability for samples immersed in fresh water and sewage after 14 days was found to be 38.8 and 55.6%, respectively. The results revealed that sewage water affects asphalt concrete pavement more severely than freshwater. Finally, it was concluded that proper drainage and adequate supplemental sewerage systems are necessary to maintain the desired strength of the pavement throughout its design life.

Road construction is essential to support connectivity, mobility, and economic growth. However, road construction can raise economic, social, and environmental issues. Many attempts have been made to develop the concept of sustainable road construction and to minimize environmental impacts by utilizing various materials. This work studies the incorporation of De-Oiled Bleaching Earth (DBE) as a filler into the Asphalt Concrete Wearing Course (AC-WC) mixture. The research objectives were first to analyze the characteristics of the ingredients that make up the AC-WC mixture and second to analyze the performance of AC-WC with DBE as a filler in terms of Marshall parameters. The results revealed that AC-WC with 10% DBE complied with the standard requirements. The highest stability was obtained with 10% DBE content, and the lowest was obtained with 90% DBE. The overall flow values of the specimens met the standards, except for the DBE content of 70% and 100%. The VIM values of the 0% and 10% DBE specimens were 4.76 and 4.87%, respectively, which met the specification standard of 3-5%. All samples exhibited VMA values ≥ 15% in accordance with the specifications. VFA values that met the specifications of ≥ 65% were obtained for DBE levels of 0, 10, 20, and 40%. MQ values that fulfilled the specification of ≥ 250 kg/mm were achieved for 0, 10, 20, 30, 40, 60, and 90% DBE. Thus, DBE can be used as a filler material in AC-WC mixtures for environmentally friendly road construction. The optimum content of DBE in the AC-WC mixtures was found to be 10%.
