Unsealed cracks allow moisture to penetrate the surface, causing pavement failure. This can lead to further cracking, potholes, and eventually major pavement breakdown, which can be expensive to repair.

 

Effective crack sealing with a hot polymer/rubberised bitumen sealant helps minimise water infiltrating the pavement base and prevent future pavement problems. It’s an effective and economical way of maintaining pavements compared to more extensive works such as resurfacing and reconstructing.

Crack sealing is used extensively worldwide, including in France, England, Germany and the USA.

 

In Australia, crack sealing has been increasingly used over the past two decades. Many local governments in all states and territories advocate crack sealing as a key element of their maintenance program. Both small and major contractors have also been using crack sealing more, as results have shown that they are able to have their repairs and new overlays last longer.

  • Water penetration
  • Movement of the pavement
  • Oxidation of the binder
  • Inadequate drainage
  • Upward reflection of underlying pavement
  • Overloading of vehicles and continued traffic use
  • Depth of pavement

An average council has over $300m worth of assets in roads. Early intervention is vital in prolonging the life of pavements. Once you can see pavement failure on the surface, the rate of deterioration accelerates.

 

Crack sealing is a key element in early intervention as it slows the deterioration process and can significantly add to the life of a pavement.

 

Having a systematic maintenance program is essential to extend the life of pavements as they help prevent cracks and slow deterioration, saving you millions long term.

CoolRoads will generally need to be reapplied every 7-9 years, but this does depend on the quality of the existing road. Its longevity is comparable to the widely used microsurfacing treatment.

CoolRoads is designed to reflect the sun’s energy to produce cooler surface temperatures through increased reflectivity.

CoolRoads is applied to asphalt, the same way conventional black sealcoats are applied. It can be used to coat playgrounds, parks, parking lots, driveways, residential areas, schools, bike paths and other community areas.

CoolRoads wears similarly to other road surface treatments. Normal street cleaning is recommended.

Heat islands, also known as urban heat islands, are areas with significantly higher temperatures than surrounding rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness, mortality, and water quality.

 

Scientific research in Australia and around the world has found that cool pavements such as CoolRoads can help mitigate heat islands.

A two-coat application is used to ensure high-quality results. When two coats are applied, any cracks or gaps remaining from the first coat are filled in. The second coat also helps to increase the lifespan of the product and save money.

CoolRoads is not white. It comes in a range of colours including concrete grey, asphalt charcoal, green and blue. It is a standard road surfacing product that meets all skid safety requirements.

CoolRoads is not a paint; it’s a high-performance road surfacing product that achieves lower surface temperatures through increased solar reflectivity.

CoolRoads products vary from 25 – 45 SRI and Emittance of 0.75 – 0.9 depending on which product is selected.

CoolSeal dries and wears similarly to other light-coloured surfaces. Normal street cleaning is recommended to maintain reflectance.
