WebMay 8, 2024 · Peck, Hanson and Thornburn (1974) suggested that there is a general relationship between PI of a soil and the potential for expansion, as shown in Table 1. However, Zapata et al. (2006) showed that the expansion potential for remolded expansive soils correlates poorly to the PI alone . They concluded that the correlation is significantly ...
