The goal is for the pavement to detect when a driver careens off the road’s edge-the kind of accident that happens dozens of times every year on Colorado’s mountainous highways.Īmy Ford, director of communications for the Colorado Department of Transportation (CDOT), says that section of highway cannot easily be widened and is too narrow to support the addition of a guardrail. If all goes well in that first test, Integrated Roadways will replace 500 meters of pavement along a dangerous curve in Highway 285, just south of Denver, with its product in early 2019. It’s one approach to so-called “smart roads,” which aim to combine sensing and intelligence in ways that reduce the hazards and hassles of vehicular travel. The company can then use that data to alert authorities to accidents or prompt officials to reconfigure lanes to relieve congestion. Integrated Roadways says its product, which can deduce the speed, weight, and direction of a vehicle from the basket of sensors buried in the pavement, will face its first real-world test at that discreet Denver junction. The company has encased assorted electronics within four slabs of concrete and will wedge those slabs into the road between a Pepsi Co.

To introduce these new features, Timm presented a webinar on May 30, 2017, on how to use PerRoad 4.3 to compare mixes developed through the 1993 AASHTO Pavement Design Procedure, the AASHTO MEPDG process, and other M-E Design procedures.On 30 August, a startup plans to add its “smart pavement” to an intersection in an industrial corner of Denver. “By coupling layered elastic analysis with a statistical analysis procedure, the program helps a designer understand the layer thicknesses and other values that will ensure long-life pavement.” “Perpetual pavement designs allow us to limit distresses to the easily repaired surface,” says PerRoad developer David Timm, PE.

It's available for free from You can also download PerRoadXpress 1.0, an all-on-one-screen program for low- and medium-volume roads and parking lots, from that page for free. New features allow users to compare M-E with perpetual pavement designs and use strain distribution or a single endurance limit strain value to design a perpetual pavement. Incorporating recent research conducted on the center's test track and validated with live traffic on perpetual pavement sections, Version 4.3 provides results as percentile responses and as conventional designs with transfer functions.

The software couples layered elastic analysis with a statistical analysis procedure (Monte Carlo simulation) to estimate stresses and strains within a pavement. Developed at the National Center for Asphalt Technology at Auburn University in Alabama, PerRoad uses the mechanistic-empirical (M-E) design philosophy to estimate stresses and strains that lead to fatigue cracking or structural rutting.
