As soon as set, concrete is a stiff and unforgiving stable substance. Nonetheless, if the floor beneath the concrete has not been made completely smooth, concrete is liable to cracking and breaking.
Asphalt is also made using aggregate. However, as a substitute of using cement as a binder, bitumen, a darkish, sticky substance derived from crude oil is used. To construct a parking lot or driveway, hot asphalt is poured onto a layer of heavier aggregate after which pressed into it with a steamroller.
