Physical Weathering Dare osinaike

Claim

Potholes are holes formed in roads as a result of a form of physical weathering known as frost wedging. Frost wedging is when water that's been absorbed through cracks in pavement freezes and then expands causing the crack to expand as well.

Rationale

The increased usage of automobiles contributes to the amount of potholes we see being formed. With the increase of use of harmful items and pollution rain has become more acidic than more, thus making it easier for it to dissolve small portions of pavement as it is absorbed through cracks. Once the temperature is low enough for the water to freeze it expands causing the pavement to weaken. Cars drive over the weakened pavement until it sinks in thus causing a pothole to be formed.

Solution

With so many potholes being formed year round companies have created a pavement patch to solve the pothole crisis. It is a hot asphalt patch and it helps make sure that the pavement does not cool down from the plant of the pothole.

By using these hot patches construction workers can fix many potholes and save many Americans from expensive repairs on their vehicles due to damage from potholes.
