In the world of road construction, there has been a gaining trend known as perpetual pavements. Continue reading to learn more about this interesting and innovative paving construction concept, including some of the most educational facts regarding the engineering of such pavements.
Perpetual Pavement Facts
The term, “perpetual pavement” refers to an inventive, tri-level, flexible road surface design and construction concept for the purpose of providing deep strength within asphalt pavements for improved longevity. Basically, it is a new engineering approach for asphalt pavements to make them stronger and last much longer.
Here are helpful engineering facts that describe the applications, benefits, and mechanics of perpetual pavements:
⇶ Design and Construction
Perpetual pavement is constructed in multiple layers to provide a strong, stable, and deeply durable roadway that can withstand inclement weather and resist tensile strain caused by traffic conditions. Only asphalt can be perpetual pavement.
The bottom layer is flexible in order to resist tensile strain and stop cracks from developing. The middle, or intermediate layer, is the permanent structural section of the pavement. And the final top layer of rut-resistant asphalt mix completes the job and provides a smooth long-lasting paved surface.
⇶ Longevity and Benefits
The installation and maintenance procedures for perpetual pavement is convenient and inexpensive. It will not requires as much time-consuming, traffic-disrupting reconstruction or repair compared to other road construction systems.
Perpetual pavement is just that: perpetual, meaning the asphalt is meant to go on and on. Basically, they are built to last forever. The whole idea behind perpetual pavements was to develop a road construction concept that could eliminate the need for repairs, indefinitely, with only the top layer requiring routine maintenance and renewal.
When a perpetual pavement requires renewal or maintenance, professional paving contractors will use specialized milling machinery to quickly remove the top layer (which is recycled), and then install a new layer in its place to create a new surface.
⇶ Contributions and Awards
The Asphalt Pavement Alliance created the Perpetual Pavement Award program, which awards DOT’s and pavement owners who have built their roadways and lots using perpetual pavement principles. In order to qualify, pavements must be at least 35 years old and has never had any kind of structural failure.
Perpetual pavement helps our planet because it has a low environmental impact. Not only does the application of perpetual pavement conserve our natural resources, it also saves billions of dollars. Furthermore, its materials are 100% reclaimable, recyclable, and reusable.
