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 50 years or more. Pavements designed and constructed in accordance with the Perpetual Pavement concept will last in perpetuity.
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.
Only the 2”-3” wearing course needs to be replaced through a mill and fill operation every 20 years.
