Potholes can make a journey stressful and less enjoyable; you can’t help but wonder how they are formed in the first place.
Potholes are holes on the road surface, which varies in shape and size. They are caused by the presence of rain water which sinks through little cracks and enters the ground thereby weakening the soil beneath and the weight of vehicles passing over the weak areas which will eventually cause a hole on the road surface.
The two causes of potholes are; water and weight from vehicles.
The roads are not permanent, overtime they age and with the help of rain water, they create potholes. Water is very disastrous and a major factor to road destruction’s.
When there are potholes on any road surface, the vehicle owner suffers the damaged suspensions, bent wheels, exhaust, bumper, and tire punctures while the passenger suffers the tossing around. Everybody is affected.
Patching is the process of filling potholes or excavated areas in the asphalt pavement. Quick repair of potholes helps control further deterioration and expensive repair of the road. Without early patching, water can enter the sub-base and cause larger and more serious damages.
A full-depth or deep patch is considered a permanent repair; while a thin surface patch or a “throw and roll” pothole repair is usually temporary.
The materials used for patching include hot mix asphalt, asphalt emulsion mixes, stockpile patching mixes, and proprietary patching mixes with special blends of aggregate and modified binders.
Full-depth patching is the removal of the entire pavement surface layer, regardless of its thickness, over the patching area and replacing them with entirely new pavement.
Deep patching is the removal of four inches or more of the pavement surface course. Full-depth patching applies to either asphalt or concrete pavements, but deep patching applies only to asphalt pavements.
the throw-and-roll repair is a temporary solution to fix your pothole problems. All you need to do is place your asphaltic patch materials into the hole, and then drive over it with a heavy vehicle (large truck, tractor, bulldozer, etc.). It’s really that simple and less expensive. The failure rate of this method is pretty high, though.
