The Asphalt Pavement Alliance (APA) will host a webinar May 30 to provide details on the PerRoad 4.3 Perpetual Pavement design software.
The update to PerRoad allows conventional mechanistic-empirical design be directly compared to Perpetual Pavement designs, and can use “strain distribution” or “single endurance limit strain values” in the design of a Perpetual Pavement.
“Perpetual Pavement designs allow us to limit distresses to the easily repaired surface,” says PerRoad developer David Timm. “By coupling layered elastic analysis with a statistical analysis procedure, PerRoad helps a designer understand the layer thicknesses and other values that will ensure a long-life asphalt pavement.”
PerRoad is available for free on APA’s at asphaltroads.org/perroad. The free webinar, which Timm will present, is set for May 30 at 1 p.m. EDT, and registration is available here.
