eTicketing show promise of speeding process and improving accuracy at asphalt job sites


PaperlessIt seems that most everything is going electronic these days, and for good reason. Going paperless can improve business operations and decrease the amount of resources needed to get the job done. In the highway construction industry, electronic lettings have been standard operating procedure for the Iowa Department of Transportation for years. More recently, the e-Construction process removed time-consuming paper shuffling right up to the point where the asphalt truck arrives at a job site to unload.

“That’s where we’ve hit a snag in the electronic process,” said Greg Mulder, director of the Iowa DOT’s Office of Construction and Materials. “Each truck driver still carries a paper load-out ticket that is collected by the Iowa DOT inspector on the jobsite and used to document the details of the delivery.”

Working with Manatts Inc.’s Ames office, Mulder and his staff recently piloted a “proof of concept” project and developed what they think could be the next step in a paperless, efficient process for documenting asphalt deliveries to highway construction projects.

How it worked
For the initial pilot project, the Manatts’ crew began working with Earthwave Technologies, of Indianapolis, to electronically track Manatts’ trucks using a global positioning system (GPS) in what Earthwave calls the Fleetwatcher system. This system not only tracks the location of trucks through GPS, but displays important details regarding load cycle times at the plant, on the job, and travel times between.

GPS boxGPS transponders were easily installed in both company-owned and third-party trucks Manatts was using to haul hot-mix asphalt (HMA) to the job site. Additionally, GPS transponders were installed on the two pavers being used at the job. These GPS transponders sent data back at several points in the process where Geozones (which are pins placed on a digital map that allow sending automatic notifications when the transponder enters the specified area on the map) had been established.

  • A static GeoZone was set up around the HMA plant site.
  • A tighter sub-Geozone was established around the scale to zero in on load-out times.
  • A static Geozone was set up around the project’s perimeter.
  • A mobile (or moving) Geozone of approximately 20-foot radius at the paver.


The software recorded the truck’s location during the entire cycle with time-stamped data when entering the scale, leaving the plant, entering the project, backing up to the paver, and finally leaving the project and returning to the plant.

Along with this, the Fleetwatcher system updates and records an electronic trail every minute throughout the day with real-time dashboards and graphical reports to help the Iowa DOT verify that the certified product was delivered and incorporated into the project. These reports and dashboards also benefit the contractors in many ways, which have side benefits to the Iowa DOT. 

Load cycle analysis

The process worked very well as a proof of concept for tracking and verifying the product life cycle from the certified plant to installation.

To be completely successful with a paperless ticketing system, scale integration is needed with the Fleetwatcher system the Iowa DOT tested. Scale integration would allow for electronic verification of the product and tonnage to be included with the product location verification tool that Fleetwatcher already included.

What’s next
In the 2016 construction season, the Iowa DOT will conduct additional pilot projects that combine the electronic location data and reports from the initial pilot project with a new data element, electronic ticketing. The software vendor is already working on and has successfully tested integration of electronic scales report-out systems with the GPS tracking reports to give contractors a daily summary report of the tonnage and certified material types along with the GPS tracking as a part of their materials delivery solution.

Mulder said, “If everything goes as planned, our inspectors will be able to see when a truck is on the way with a mobile app in the field and be able to access electronic ticket numbers with the tonnage and certified material type electronically captured. The inspector should be able to integrate that data into daily reports without having to collect each ticket manually and key into a contractor pay spreadsheet.”

The handoffMulder continued, “While this seems like a minor detail, electronic ticketing can have a major impact on safety and efficiency at a job site. It is dangerous for our inspectors to have to collect the ticket from each truck. Waiting for trucks, taking tickets, and then manually entering the data isn’t very efficient. There are so many other things the inspector needs to be doing. If we can take this element out of the mix, it would free our people to do the actual quality control and inspection work they are on-site to complete.”

While there is a long way to go to see paperless load tickets on every job site, Mulder say next year’s pilot projects could answer a lot of outstanding questions about how electronic ticketing will work. He said, “We still need to work out the audit process, and for the next pilot project, each driver will still carry a paper ticket for verification purposes. Nonetheless, we’re looking forward to exploring electronic ticketing with scales integration and working out the details in 2016 to bring the next logical step in the e-Construction process to fruition.”
