Q0005 - SMF be used as a base?

Date Submitted: Tuesday 1 July, 2003


Can materials categorised as Special materials for fill (SMF) be used as a base (road base) granular substitute if they meet the required CBR (+30%)?


No, this material cannot be used in this way, if it were there would be no difference between it and SMR's. The distinction between SMF and Structural Material for Reinstatement (SMR) is that the SMF is categorised by CBR and used as a fill material and SMR by cube strength used in structural layers.
