 Perpetual Pavement combines the well-documented smoothness
and safety advantages of asphalt with an advanced, multi-layer
paving design process, that with routine maintenance, extends
the useful life of a roadway to half a century or more. Pavements
designed and constructed in accordance with the Perpetual
Pavement concept will last, and last, and last.
How it works
Perpetual Pavements use multiple layers of durable asphalt
to produce a safe, smooth, long-lasting road. The Hot Mix
Asphalt (HMA) design begins with a strong, yet flexible bottom
layer that resists tensile strain caused by traffic, and
thus stops cracks from forming in the bottom of the pavement.
A strong intermediate layer completes the permanent structural
portion, and a final layer of rut-resistant HMA yields a
surface that lasts many years before scheduled restoration.
A Perpetual Pavement provides a durable, safe, smooth, long-lasting
roadway without expensive, time-consuming and traffic-disrupting
reconstruction or major repair.
Major advantages
When scheduled surface restoration is performed, Perpetual
Pavements can be maintained easily and cost-effectively without
removing the road structure for reconstruction, saving time
and money while keeping motorists happy.
Asphalt is recyclable, providing further cost savings and
environmental benefits.
Asphalt has a proven safety record as a driving surface,
offering stronger visual contrast with center stripes and
other markings. Among other advantages can include reduced
noise, reduced splash and spray, and greater skid resistance.
