1 GeneralThe main consideration when con-structing roads on poor load-bear-ing subsoil is that every load deformsthe soft soil layers; and the greaterthe load, the greater the deforma-tion. This deformation process con-tinues over years, depending on thethickness of the soil layers. The lowshear resistance of poor loadbear-ing subsoils means that concen-trated loads should be avoided asfar as possible, otherwise theselayers will give at the sides. Com-pensating for this form of subsi-dence by laying new material leadsto further settlement due to theadditional conventional techniques of sub-soil improvement by complete orpartial replacement of the soil areoften time consuming and thereforecostly.
