Maintaining and improving infrastructure is always a constant and when it comes to road rehabilitation, it demands a diverse array of processes to restore the integrity and safety of our roadways. Here are five key applications for road rehabilitation, why it's important and the tools involved.
When roads suffer extensive damage that compromises their structural integrity, pavement replacement is an excellent solution. This process involves removing and replacing the damaged layers of the road, ensuring it can handle traffic loads without further deterioration. This not only enhances safety but also extends the road's lifespan.
Fine milling is a highly effective technique for smoothing out surface irregularities like bumps, ruts or slippery spots on the road. The method breathes new life into worn-out pavements, offering a less invasive alternative to full pavement replacement. Fine milling is quick and efficient and can be a cost-effective solution that helps extend the life of the road without the need for extensive repairs, making it a smart choice for maintaining our infrastructure.

Another effective way to restore the road's surface is through hot recycling. This process involves reheating and reusing existing asphalt materials directly on-site. It not only revitalizes the road but also conserves resources. By reducing the need for new materials and minimizing waste, hot recycling can be environmentally friendly and reduce costs.
In-situ cold recycling is a technique that revitalizes existing pavement materials directly on-site by mixing them with stabilizing agents like cement or asphalt emulsion. This method strengthens the road foundation and extends its lifespan.

The full-depth reclamation (FDR) method pulverizes the existing pavement and base materials and then mixes them with stabilizing agents, compacting them to form a new layer of pavement. By recycling the existing materials on-site, FDR minimizes waste, making it an environmentally friendly option.
