Structure Application
Surpro was designed to measure structure and contains several features to make structure data collection faster, safer and more accurate. For structure applications Surpro provides the following features:
  • High speed of data collection reduces operators' exposure to traffic hazards. Two ultra-bright flashing LED lights to make the Surpro profiler more visible in the field.
  • Patented rolling inclinometer with Inertial Stabilizer loaded damped suspension to ensure stability and accuracy for all speeds and surface conditions by ensuring profiler wheels are always in contact with surface.
  • High accuracy results at data collection speeds up to 4 km/hr (2.5 mile/hr) while achieving accuracy comparable to low speed devices such as Dipstick at 0.24 km/hr (0.15 mile/hr).
  • Structures such as bridges can be profiled before approaches are constructed. Surpro collects accurate data from 0 to 4 km/hr (2.5 mile/hr) and does not need to first "get-up-to-speed" on an approach section.
  • Class 1 profiling performance.
  • Fully automated data collection for longitudinal and transverse (cross slope) profiles.
  • Adjustable wheel and sample spacing of 250 mm, 12" and 300 mm to comply with various standards.
  • User selectable sample intervals from 0.05 to 1m (1.97 to 39.4") can be any value smaller, equal to, or larger than wheel spacing.
  • Very high accuracy and repeatability.
  • Unfiltered true elevation profiles (similar to rod and level and Dipstick).
  • Profilograph-equivalent output by accurate mathematical conversion from true profile to California, Rainhart and Rolling Straightedge profilers.
  • Multiple roughness indices (IRI, RN, PRI or PI).
  • IRI Bump Analysis Module that strategically and optimally finds bumps and dips and proposes optimized grind/fill strategies to achieve target IRI roughness index values with minimum grinding or filling.
  • Built in programmable digital filters (3rd Order Butterworth) and moving average filters.
  • Prints profile and roughness information on-site using mobile printer without a notebook computer.
  • Produces complete, high quality graphs and tabular text reports.
  • Can be checked on a commercial aircraft as passenger luggage.
  • Permanently stored calibration; does not require calibration for every use.
  • Battery life 20 hrs without motor drive connected.
  • Durable and weather resistant (no laptop computer exposed to the elements).
  • Optional FM radio remote controlled motor drive enables data collection at 2.5 mile/hour.
Various Structure Uses
  • Management and maintenance of any structure surface.
  • Acquisition of new structure profile data for comparison with end-product specification for contract bonus/penalty determination.
  • Identification and correction of traveled surface defects to achieve target roughness indices (using IRI Bump Analysis Module).
  • Calibration site establishment.
  • Equipment performance verification.
Description of Typical Structure Use
  • Transport to site by air or vehicle. Surpro weighs only 20.4 kg (42 lb) and fits in a typical car's trunk.
  • Unload from vehicle and assemble in about 5 to 10 minutes.
  • Calibration values are permanently stored in Surpro but calibration can be accomplished or verified in about 5 to 10 minutes.
  • Calibration of level is accomplished by performing a small closed loop profile.
  • Verification is accomplished by placing a test block under either of Surpro's wheels.
  • Set up Surpro using simple keypad, backlit 4 line LCD display and menu system.
  • Enter description of site being testing (menu general data fields).
  • Enter control parameters and other options as appropriate (menu control data fields).
  • Enter profiling direction (forward or reverse).
  • Press RUN and collect data by pushing Surpro at any speed up to the specified maximum. Data collection can be interrupted without influencing the data.
  • Press STOP and save file to permanent on-board storage.
  • View results and key data parameters using RECALL key.
  • Print reports using PRINT key.
  • Create report data files for later use using PRINT key.
  • Transfer profile data (PFL, ERD, EVT) and report data (TIF, IRI, RN, PRI, ZON, BUM) files to a laptop computer using SEND key.
  • Analyze and filter data with ICC SurPRO Utility software.
  • Erase data in preparation for another run using CLR key.
Analysis and Reports
  • Graph of entire unfiltered profile with title block summary of all key profiler configuration, test description and test result data:
  • User may also design a custom filter and produce a filtered profile report.
  • IRI and RN support:
  • Tabular listing of IRI and RN by user specified section length.
  • Tabular listing of IRI and RN by user specified section start and stop distances using keypad control and user event input.
  • Tabular listing of IRI and RN by Roughness On/Roughness Off (Ron/Roff) using keypad control and user event input.
  • IRI Smoothness Analysis Module reports including:
  • Graphical report for section identifying each bump and showing start and end; length; height; recommended grind start, end and minimum depth.
  • Tabular report for section showing bump start and end; length, height; recommended grind start, end and minimum depth; and IRI reduction achieved by grinding or filling each bump or dip. Detailed multiple pass grinding plan.
  • Graphical report for IRI Out-of-Spec Zones in total profile that have average IRI that exceeds IRI Target, identifying each bump and showing start and end; length; height; recommended grind start, end and minimum depth.
  • Tabular report of IRI Out-of-Spec Zones in total profile and Histograph of IRI.
  • Tabular report for total profile, using zone analysis, showing bump start and end; length, height; recommended grind start, end and minimum depth; and IRI reduction achieved by grinding or filling each bump or dip.
  • PRI or PI support:
  • Graph of PRI or PI, scallops and must grind bumps by user specified section length.
  • Tabular listing of PRI or PI by user specified section length.
