Mar 10, 2017· A good indicator of the rigidity of materials is their tensile or shear strength. The tensile strength of concrete is about 5,000 PSI. The tensile strength of asphalt is about 200 PSI at 70 degrees F when measured for short-term forces. Under continuous forces, the asphalt "creeps" and the resistance drops with time. The creep starts as soon as ...

Concrete Expansion Over Time May Cause Reflective Cracks. Concrete has expansion joints where asphalt does not. Over time, the expansion joints will shift the concrete surface and wherever your concrete has a crack, the asphalt will eventually crack there as well. The expansion joint in the concrete is a designed area to allow for a crack, and ...

Concrete vs. Asphalt. Concrete is a mixture of cement, water, and an aggregate such as sand, gravel, or crushed stone. It has a lot more grit and is less slippery than asphalt. Concrete is typically used as pavement, which is meant for foot traffic. Asphalt, on the other hand, is aggregate mixed with a binder, which is a petroleum-based substance.
