Full Answer

Parking lots are typically made of porous asphalt because it allows water to drain effectively and improves the quality of groundwater. Roads are usually made of perpetual pavement because it is multilayered and only needs its top layer replaced periodically. Hot mix typically finds use in driveways as it is durable and provides a finished look that homeowners find attractive. Warm mix asphalt blends at lower temperatures, which reduces fuel costs and allows for paving in colder weather. Residential roads are often comprised of quiet asphalt because it reduces noise pollution, creating a peaceful area for nearby homeowners.
