• 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.
