From Figure 3 it can also be inferred that the dolerite rock is sound with regard to its PI and should be durable for use as surfacing aggregate and Crushed Stone (G1) base. Unfortunately, this approach has led to some premature failures in the past, as mentioned above, and to dolerite increasingly being avoided for this type of application.
