This report describes a literature review on the permeability of sprayed seal surfacings. This review work was conducted to explore the permeability limits of sprayed seal surfacings, and to determine the influencing factors which allow seals to…
This document is an update of the design of initial treatments for sprayed seal surfacing.
The information contained within this document supersedes that found in Austroads AP-T68-06 Update of the Austroads Sprayed Seal Design Method, and replaces…
The principal aim of this work was to examine the effect of heavy vehicle loading on sprayed seals, in order to incorporate such loading impacts into the Austroads sprayed seal design method.
The current sprayed seal design method uses an equivalent…
The current version of the Austroads sprayed seal design method was published in 2006 and has been in use for the last nine years. During recent times, a number of sprayed sealing practitioners have indicated that the basic voids factor for single/…
Traffic loadings on Australia’s extensive sprayed seal network have increased, particularly with freight efficiency resulting in longer and heavier loads being transported by prime movers.
This report details the development of a model to describe…
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…
This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,
A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…
This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.
