“…This research will enable excavated soft Bangkok clay traditionally destined for landfill to develop sustainable lightweight pavement materials, which are significant in terms of engineering, economical and environmental perspectives. This research outcome can be applied to other marine clays such as Changi clay in Singapore, Ariake clay in Japan, and Pusan clay in Korea (Ohtsubo et al, 2000;Tanaka et al, 2001;Arulrajah et al, 2007;Arulrajah and Bo, 2008;Chu et al, 2009). C = cement; AF = air foam; CXXX = mix proportion of cement weight to wet soil volume in (kg/m 3 ); AFYY = mix proportion of air-foam content to wet soil volume in (%); NA* = not available data due to the mixture of specimen is unstable (large segregation of mixture specimen).…”
