What causes potholes or large cracks in a pavement to appear in a street?

The main cause is in cold climates water gets into a tiny crack and then freezes and expands causing the crack to get larger and then when cars drive on it it will eventually cause the top layer of asphalt to break off. In warmer climates the constant wear of vehicles and heat from the sun dries the asphalt and causes the top layers of asphalt to crack, which can widen from rain water. Little cracks like in drive ways are usually caused by roots which can cause cement to crack and break up. To read more see attached link.

Why is concrete weak in tension?

Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding metal reinforcing bars, glass fiber, or plastic fiber to carry tensile loads
