How to ensure that roads are safe to drive?

road construction

When it comes to the safety while driving, we are asked to follow countless driving tips such as wear your seatbelts, be cautious while driving, don’t drink and drive, maintain the right speed limit, and so on. But these aren’t the only factors that will ensure you have a safe ride. The roads that we drive on should also be in good condition to avoid skids and falls. Right from the road construction stage to the timely maintenance, road construction companies should be careful to ensure that roads are safe to drive.

As damages to the asphalt roads over time is common, the concerned authorities should carry out the following techniques for complete safety of the vehicle drivers.

Patching

Patching is the process of filling potholes or excavated areas in the asphalt roads. Quick repair of potholes or other disintegration not only helps in controlling further deterioration of the road but also ensures a smooth, uninterrupted ride. Common materials for patching include hot mix asphalt, asphalt emulsion mixes, stockpile patching mixes, and patching mixes with special blends of aggregate and modified binders. The full-depth patching is the permanent solution for various road defects. The process involves removal of the entire road surface layer around the defect and applying patches of the best patching material.

Crack Filling

If the asphalt road has developed multiple cracks, it surely needs some crack filling treatment. Crack filling refers to the process of blowing out and cleaning crevices before installation of a crack filler material. This is also known as the “blow-and-go” method. Common materials for crack filling include asphalt emulsions, fiberized asphalt, and polymer-modified emulsions. Crack filling reduces the seepage of water on the road surface, which can weaken the aggregate base and subgrade materials.

Sealcoating

Sealcoating the asphalt roads has numerous aesthetic and functional benefits. Exposure to oxygen hardens asphalt binders and results in a brittle pavement surface that soon cracks. Sealcoating slows the oxidation process and keeps the surface rigid for a longer period. Also, sealcoating prevents water penetration that can damage the paving materials beneath the road. Furthermore, gasoline and other products derived from petroleum such as oils and fuels, fats, grease, mineral spirits, etc. easily dissolve asphalt. Sealcoating solves these and several other problems on the road that can possibly hinder a smooth vehicle ride. Asphalt or coal tar emulsions and aggregate-based seals are the most commonly used sealants for sealcoating asphalt roads.

Drainage Management

A good drainage system should be able to drain rainwater and melted snow away from the road and prevent flooding the roadway or adjacent property. Also, water should not be allowed to accumulate over the road surface for too long. Standing water on the roads can increase the chances of skids, slips, and accidents. Thus, it is essential to build a good drainage system including the right sloping and drainage chambers to ensure that water flows away quickly after every rain.

The authorities can get in touch with a renowned road construction company to carry out these repair and renovation procedures. The road construction company will also provide several other types of road repairs based on the severity of damage to the asphalt surfaces.
