• Abstract:
  DOTD conducted a demonstration ; project to evaluate intelligent compaction (IC). The ; project developed specifications, which allo ; wed and incorporated ; the IC rollers on the ; project. The specification went through th ; e competitive bidding process and produced a ; wide range of cost numbers. The item for the ; soil roller had a range of ; bids from $15,000 to ; $95,000. The item for the asphalt roller ha ; d a range in bids from $7,000 to $100,000. The ; range may be attributed to the lack of knowle ; dge and familiarity within Louisiana regarding ; the intelligent compaction technology. This proj ; ect sought to increase the knowledge base of ; IC in Louisiana. ; DOTD/LTRC hosted a showcase on the pilot pr ; oject, which provided ; presentations from ; researchers, FHWA, and manufacturers. Th ; e showcase highlighted the US 90 Frontage ; Roads project, which collected both soil and as ; phalt data with two different rollers. The ; project was well attende ; d and well received. ; Manufacturer equipment and software training/su ; pport are critical to th ; e success of an IC ; project, which includes good co ; mmunication throughout. In this ; case, the contractor had ; relationships with each roller ma ; nufacturer, and LTRC was able to ; interact with roller and ; manufacturer. Initial setup of ; roller and GPS connections was a challenge with both project ; rollers, as LTRC local roller representatives a ; nd the contractor were ; generally learning about ; the details of the technology for the first time. ; National roller represen ; tatives were helpful, ; but could not be on site at all times. The cont ; ractor’s survey staff became proficient in the ; two systems; and needed GPS knowledge; capable ; , accurate, and reliable GPS equipment; as ; well as the ability to connect properly and effect ; ively with the rollers’ ; on-board software. ; The contractor can realize some ; advantages through the utilizati ; on of the rollers. Operators ; can adjust patterns and time based on real-time ; reactions/display, and the roller display can ; show and track coverage, passes, and comp ; action effort (measurement values) hopefully ; speeding production and assis ; ting with quality control. Weak ; areas can be visually identified ; on the roller’s real-time screen through installed software for rework. ; Through the use of the IC technology, by the co ; ntractor, the Departme ; nt can also realize ; some advantages. The rollers continuous covera ; ge records (vs. point ; tests at roughly 1000-ft. ; spacing) can speed construction ; with contractor’s use (appr ; opriate passes/energy). The ; technology promotes consistent and uniform paveme ; nt layers, which can be visually verified ; by the roller real-time screen.
