Blacktown City Council is leading the way in reducing urban heat after taking part in the trial of an innovative coating on local roads – the first trial of its kind among NSW councils.
The local council says it was proud to partner with Western Sydney University (WSU), City of Parramatta Council and Campbelltown City Council to investigate the effects of CoolSeal coating in reducing surface heat on roads and carparks.
The light grey-coloured coating was trialled on five streets in Ropes Crossing last year, with heat monitoring conducted by WSU over summer.
Recently-released results from the trial show that unshaded pavements coated in CoolSeal were between 6 and 11°C cooler than uncoated pavements.

Blacktown Mayor Tony Bleasdale said the revolutionary trial was a positive step in Council exploring measures to combat the issue of rising urban heat.
“In recent years, we have seen the catastrophic consequences of rising temperatures on our environment and therefore Council is committed to reducing heat stress in Blacktown City,” Mayor Bleasdale said.
“Urban development and climate change are accelerating this issue, with climate modelling for our region predicting an increase of up to 10 days over 35°C over the coming years.
“Studies have found that increasing heat is the largest risk to local populations and economies across our region.
“Blacktown City and Western Sydney consistently record higher summer temperatures than the average for metropolitan Sydney, so it is crucial we look at ways to reduce the urban heat impact and improve quality of life in our City.
“Council is a leading force in the fight against climate change, and our participation in this trial shows our commitment to cool road solutions.”
The trial found that the product was especially effective in reducing the surface temperatures of unshaded surfaces on hot days. The effect on ambient temperatures is yet to be determined due to the limited size of the trial areas.
Council is also exploring additional measures to reduce the temperature of road surfaces. Such measures include: the use of light-coloured aggregate in road surfacing, the use of clear asphalt binder in place of black binder and the use of concrete pavements.
