Surface Treatment

Surface treatment is designed to protect roadways from both sun exposure and moisture. The process involves applying an asphalt emulsion to an existing asphalt road or over a granular surface, followed by the application of a cover aggregate. Typically used on lower-volume roads, surface treatment can be applied in either a single or double application, depending on the specific needs of the road.

Surface Treatment Process:

Liquid asphalt emulsion is applied to the road surface, which is then covered with fine aggregate. Rollers compact the fine aggregate into the emulsion, ensuring a secure bond. Afterward, sweepers remove any loose aggregate to minimize dust and ensure a clean finish.

How will surface treatment improve the road?

•          Increases Skid Resistance: Enhances traction, improving safety, especially in wet conditions.
•          Prevents Moisture Intrusion: Protects underlying materials from water infiltration, reducing potential damage.
•          Provides Anti-Glare Surface: Reduces glare during wet weather, improving visibility for drivers.

What are the benefits of surface treatment?

• Cost-Effective: More affordable compared to other road maintenance methods.
• Time-Efficient: Requires less time to apply than alternative construction techniques.
• Extends Road Lifespan: Helps to prolong the life of the road, reducing the need for frequent repairs.

What can you expect during construction?

•          Dust: Some dust may be generated during the application process.
•          Lane Closures: Temporary closures may be necessary to accommodate the work.
•          Traffic Delays: Expect potential delays as the work progresses.
• Large Equipment: Heavy machinery will be operating within the roadway during the construction process.
