Like concrete, asphalt is made using aggregate. Its binder, however, is bitumen, a dark, sticky substance derived from crude oil. When roads, parking lots or driveways are built using asphalt construction, hot asphalt (bitumen mixed with fine aggregate) is poured onto a bed of heavier aggregate and then pressed into it with a steamroller ...

Generally speaking, a concrete surface will outlast an asphalt surface. Most concrete pavements have lifespans of between 30 and 50 years. The average asphalt pavement, by contrast, usually lasts between 12 and 20 years. Of course, numerous factors will affect the lifespan of either type of pavement.

Concrete pavements are constructed with a concrete surface typically poured in one lift over the soils. These pavements are referred to as "rigid" due to the greater stiffness of the material compared to asphalt. A few reasons asphalt pavements are selected include: Asphalt pavements have a lower initial construction cost, allowing agencies ...

To start, pavements have historically been divided into two general categories – flexible and rigid. Now, these traditional definitions tend to be a bit of an oversimplification, but they do provide a description of how asphalt and concrete each react to force loads and the environment. Between the two, asphalt pavement is the flexible variety.
