• Abstract:
  Keeping Oklahoma’s roadways, highways, and bridges in good condition is necessary to our ; state’s safety and to avoid expenditures in billions of dollars each year for road repairs and ; replacement. According to a study done by state of Oregon in 2009, heavy vehicles account for ; 79% (or $60 million) of annual expenditures required for roadway repaving. Likewise, they were ; also responsible for 66.8% (or $27 million) of pavement and shoulder reconstruction; 65.1% (or ; $145 million) of pavement and shoulder rehabilitations; and 61.5% (or $140 million) of pavement ; maintenance. To weigh traveling trucks, the state of Oklahoma has installed 20 permanent ; Weigh-in-Motion (WIM) sites. Expanding site coverage to include additional roadways and ; highways improves data accuracy; however, it requires significant roadside construction and ; costly infrastructure support. This report presents deployment results of a novel portable WIM ; system and compares captured data with that collected at a nearby permanent WIM system. ; Design, development, and road-installation details of the heavy-vehicle centric, portable WIM ; system are also provided. Outcomes demonstrate that the portable system maintains data ; quality but for short intervals and provides a viable alternative to permanent systems at merely ; 10 percent of the cost. The portable WIM system uses off-the-shelf components and ; commercially available WIM controllers. The WIM controller used was IRD iSINC Lite. ; The fabricated portable system could be promoted as an alternative WIM monitoring solution to ; permanent WIM systems and/or static scale stations, both of which are extremely expensive to ; install on highways. The portable WIM uses RoadTrax BL piezoelectric class-1 sensors, ; galvanized metal fixtures equipped with pocket tapes to house the sensors, and a trailer with ; cabinet to house WIM electronics, batteries, and REECE device for real-time monitoring. The ; system is solar powered with three 100-Watt panels, and it costs roughly $20,000.
