This report details investigations that were conducted to verify the new Austroads sprayed seal design guidelines.
To verify the appropriateness of the proposed basic voids factor (Vf), and the initial sealing design approach (and also to validate…
This report describes research into development of a laboratory sprayed seal binder cracking test which can be used to measure the relative fatigue cracking resistance of thin binder films which have thicknesses comparable to the thicknesses of the…
Some recent problems with polymer modified binder (PMB) seals have been attributed to lack of initial adhesion of the binder to the sealing aggregate. This suggests that higher levels of cutter than those given in an Austroads Guide may be necessary.…
