Evans Shire Council NSW Project: Use of Polymer Stabilisation
In June 2003, Evans Shire Council evaluated Polyroad as a pavement
stabiliser for one of Council's local roads, Triangle Flat Road, Rockley
to Trunkey. Based on economic grounds and pre-construction tests results,
Council chose to proceed with Polyroad stabilisation.

Polyroad - Yet Another Alternative
In late 2000/early 2001, a project on the Winton - Hughenden road
suffered significant distress, very early in the life of the pavement (in
fact, one section had severe wheel rutting as a result of construction
traffic).
The problem was later identified, through audit, that, although the
base material generally met the specification, it was a very sandy
material which completely lacked cohesion. As a result, when trafficked,
especially after rainfall, the pavement severely rutted and shoved.
Several sections were repaired using a combination of lime/flyash/cement
through a pug/pave operation. This was successful, however the already
placed/sealed sections couldn't be economically treated the same way.
An alternative was sought which allowed treatment insitu, while
providing a waterproof, stable unbound pavement material.

Taree Airport Project
Polymer-stabilisation of a section of the Taree runway is one of the
earlier Australian examples of this type of rehabilitation treatment. The
top 150mm of conglomerate gravel basecourse was polymer-stabilised insitu
in September 1988 and resealed. It continues to perform well after ten
years. This contrasts with the previous runway performance where localised
rutting under the Fokker Friendship aircraft necessitated frequent
patching. The failures typically developed after periods of rain.

Yass Shire Council Project Update
In 1996 Yass Shire Council began evaluation of Polyroad as a pavement
stabiliser in heavy patching work on two RTA Main Roads (MR84 & MR56)
maintained by the Shire. The results were so encouraging that Council now
use Polyroad for both general road rehabilitation and maintenance patching
on its own shire roads and on RTA roads.
