This report describes inspections conducted on double/double primerseals constructed in Victoria.

It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads specification or guidance documents.

The double/double seals were found to be performing well, and providing a viable option for an initial seal over a pavement where stresses can be expected to be higher than ideal for a typical single/single primerseal.
