Asphalt and concrete are probably the most common types of pavement used for several projects, such as driveways, parking lots, roads, sidewalks, etc.
Both materials are beneficial in their own right. Here are the benefits of asphalt and concrete.
Benefits of Asphalt
94% of US roads are paved with asphalt, and for good reason. Asphalt pavements are:
Asphalt pavement provides a high level of skid resistance and a high contrast in color between the black asphalt pavement and white and yellow road markers, which gives drivers better road visibility in any condition of weather.
Additionally, asphalt’s dark color melts snow and ice much more rapidly than all the other pavement types. Open-graded asphalt is able to minimize splash during rainstorms— ultimately reducing crashes and fatalities on highways. Asphalt pavement also eliminates potentially life-threatening and expensive pavement blowups.
Asphalt pavements are a much more uniform surface, unmatched by other types of pavements. Smooth roads are safer because uneven and surfaces decrease driver’s control when driving, increasing driver fatigue.
Additionally, smooth asphalt roads lessen rolling resistance (i.e. the friction caused when tires drive over the pavement), which ultimately means better fuel economy and a reduction in carbon dioxide emissions.
Roadway noise can be an annoying distraction both in your car and at home. Asphalt roads assist in the reduction of highway noise by as much as seven decibels.
Additionally, streets made of asphalt reduce the need for costly sound barriers, which often exceed $2 million per mile.
Benefits of Concrete
Lowest Carbon Footprint
Concrete’s unmatched durability, recyclability, and energy efficiency— in tandem with industry innovations like lower carbon Portland-limestone cement, i.e. Contempra— all contribute to its status as the lowest carbon-building material over the entire lifecycle of pavement or a structure.
Strong and Durable
Concrete lasts for decades longer than other building materials—actually getting stronger over time. This equals the reduction of the total cost of ownership, in addition to the environmental impact related to more frequent reconstruction or rehabilitation.
Concrete doesn’t rot, rust, or burn. Its resistance to fire, wind, water, vibrations, and earthquakes keeps people safer and reduces costs related to any sort of damage. When it comes to the aftermath of extreme weather conditions, concrete structures have proven themselves to be the most resilient.
