Cracks in asphalt roads are not only unsightly but can also lead to significant damage if left untreated. Over time, moisture, temperature changes, and traffic loads can weaken the surface, causing cracks to spread and eventually lead to potholes or surface degradation. One of the most effective methods to prevent these cracks from forming is the use of spray and seal bitumen. At Craigieburn Road Tech, we offer professional spray and seal services designed to protect and extend the life of your asphalt roads in Craigieburn, VIC.
What is Spray & Seal Bitumen?
Spray and seal bitumen is a surfacing technique that involves spraying a layer of hot bitumen over an existing asphalt surface, followed by the application of an aggregate, such as gravel or crushed stone. This method creates a protective seal over the asphalt, preventing moisture penetration and protecting the surface from the damaging effects of weather, traffic, and wear and tear.
How Spray & Seal Bitumen Prevents Cracks
- Moisture Barrier
Water is one of the leading causes of asphalt road damage. When water seeps into the cracks and pores of the asphalt, it weakens the foundation and can lead to erosion beneath the surface. During colder months, water trapped in cracks can freeze and expand, causing the asphalt to crack further. The spray and seal bitumen method creates a waterproof barrier that prevents moisture from infiltrating the surface, significantly reducing the risk of water-related damage. - Protection from UV Rays
Asphalt roads in Australia are exposed to high levels of sunlight, particularly during the summer months. Over time, the UV rays from the sun can cause the asphalt to dry out and become brittle, which makes it more prone to cracking. The bitumen in spray and seal acts as a protective layer, shielding the asphalt from direct UV exposure and helping to maintain its flexibility and strength. - Enhanced Flexibility
One of the benefits of spray and seal bitumen is that it provides a flexible layer that can adapt to minor movements in the underlying asphalt surface. Roads are subject to expansion and contraction due to temperature fluctuations. Without this flexibility, the asphalt surface would be more likely to crack under pressure. The bitumen layer absorbs these stresses, reducing the likelihood of cracks forming. - Traffic Load Management
Heavy traffic and constant vehicle movement put significant pressure on asphalt surfaces. Over time, this load can cause the surface to crack, especially in areas with high volumes of vehicles or heavy trucks. Spray and seal bitumen reinforces the surface, helping it to distribute weight more evenly and prevent damage caused by concentrated traffic loads. - Improved Aggregate Bonding
In the spray and seal process, the bitumen acts as an adhesive, bonding the aggregate layer to the asphalt surface. This additional layer of aggregate helps protect the asphalt from direct contact with tyres, reducing the wear and tear caused by traffic and enhancing the overall durability of the road. The aggregate also provides additional texture, improving grip and reducing the risk of accidents in wet conditions.
When to Consider Spray & Seal Bitumen for Your Asphalt Roads
If you notice small cracks forming on your asphalt surface, it’s important to address them before they become more serious issues. Spray and seal bitumen is an excellent preventive measure that can extend the life of your road, driveway, or car park by protecting it from the factors that contribute to cracking and surface deterioration.
At Craigieburn Road Tech, we recommend applying spray and seal bitumen as part of a regular maintenance plan, especially in areas that are subject to heavy traffic or extreme weather conditions. Early intervention can save you time and money by preventing the need for more extensive repairs or resurfacing in the future.
