Bituminous surface treatment, also known as BST or chip seal, is a cost-effective method of preserving and maintaining roads. It involves the application of a thin layer of asphalt emulsion, followed by a layer of aggregate (gravel, slag, or crushed rock), to form a durable, skid-resistant surface. BST is widely used by cities, counties, and states to extend the life of roads and keep them in good condition.
Here are some of the benefits of using the bituminous surface treatment for road preservation and maintenance:
- Cost-effectiveness: BST is one of the most affordable methods of road preservation and maintenance. It is a fraction of the cost of traditional asphalt paving, making it a popular choice for local governments and road departments that need to maintain large amounts of roadways on a tight budget.
- Durability: BST provides a long-lasting, durable surface that can withstand heavy traffic, harsh weather conditions, and the daily wear and tear of vehicles. The aggregate layer helps to protect the underlying asphalt, reducing the need for frequent repairs and resurfacing. Improved driving conditions: BST provides a skid-resistant surface that improves traction and makes roads safer for drivers. It also helps to reduce the risk of hydroplaning during wet weather, making roads safer and more manageable.
- Easy maintenance: BST is easy to maintain, with regular sweeping and filling of cracks and voids all that is required to keep the surface in good condition. This reduces the need for more intensive maintenance, such as resurfacing and extends the life of the road.
- Eco-friendliness: BST is an environmentally friendly option, as it helps to reduce the number of materials used in road construction and maintenance. It also reduces the need for frequent resurfacing, which requires heavy machinery and produces emissions.
In conclusion, bituminous surface treatment is a cost-effective and durable solution for preserving and maintaining roads. It provides improved driving conditions, is easy to maintain, and is environmentally friendly. If you’re responsible for road maintenance and preservation, consider incorporating BST into your road preservation program.
