This study sought to extend the understanding of pavement works effects (WE) by extending the scope of WE treatments and evaluation measures previously used.
The study was based on data extracted from Austroads long?term pavement performance (LTPP) and LTPP for maintenance (LTPPM) sites. This produced a relatively small sample size of 47 sample sites spread across seven WE treatments.
Modelling was applied to five WE treatments: asphaltic overlays, patching, mill and replace, resealing and resheeting. The evaluation measures included roughness, rutting and deflection and yielded acceptable, and where sub?sample numbers were adequate, robust findings for WE modelling.
