This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne, Victoria; and a polymer modified binder (PMB) trial near Coober Pedy, South Australia and Cooma, New South Wales.
Austroads has established a project to monitor, interpret and report on the long-term performance of the Gisborne non-modified binder trial established under Austroads project TT1357 and the early life performance of the Austroads PMB sprayed seal trials established under TT1665.
After seven years of life, seals at the Gisborne non-modified binder trial were performing well. After two years the PMB trials were performing well in all cases at the Coober Pedy site, but showing signs of distress in some sections at Cooma.
