Councils across Australia are modernising their road maintenance programs with an innovative, dual award-winning solution.
Re-sheeting was once the norm when maintaining unsealed roads. However, as gravel pits close due to environmental and other concerns, the challenge of sourcing good materials continues to rise. The purchase price has become more and more inhibitive for road authorities.
There are also several other factors to consider when evaluating the real cost of re-sheeting.
1. Repeated heavy truck loading to the section being re-sheeted leads to deterioration of the council roads leading to the road being maintained. ‘Chasing your own tail’ in this way is not financially sustainable.
2. As gravel pits continue to close for environmental and other concerns, the purchase of material and cost of transport to site becomes more expensive. Heavy trucking routes are then extended, resulting in further cost to road authorities.
One of the many reasons new material is imported is to overlay clayey materials which soften when wet, making for dangerous driving conditions. These sections then require ongoing maintenance to meet service intervention levels.
Councils are adopting a new practise to rejuvenate their existing road materials without bringing in new material - at basically half the cost of re-sheeting. Their solution decreases the need for maintenance grading by an average of four to six times.
For a lesser dollar value than re-sheeting, the outcome is an unsealed road that requires less maintenance, performs better in wet weather and produces less dust in the dry by utilising existing clayey or higher PI materials. The road maintains shape, and saves the damage caused by heavy truck movements to council roads both sealed and unsealed.
Studies reveal this is easily achievable with PolyCom Stabilising Aid, a high performing environment and OHS compliant road stabilisation aid, with applications for sealed and unsealed road construction and maintenance, mining haul road maintenance, transport hardstands, embankment stabilisation and general earthworks.
Winner of the 2014 Banksia Awards and 2014 Premier’s Sustainability Awards, PolyCom enables councils to stabilise the in-situ road materials to create a stronger, longer lasting road pavement. Reduced maintenance requirements means less road work disruptions. A stronger running surface means less potholes - and less ratepayer complaints.
