Road Application Description

Surpro was designed to measure roads and contains several features to make road data collection faster, safer and more accurate. For road applications Surpro provides the following features:
High speed of data collection reduces operators' exposure to traffic hazards. Two ultra-bright flashing LED lights make the Surpro profiler more visible in the field
Patented[1] 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 road 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)
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[2])
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)
Smoothness Analysis that optimises IRI using several strategies and provides Bump Grinding Plans. SurPRO finds Bumps in Profile Sections and Bumps in Out-of-Spec Zones in Total Profile and it provides a grinding plan to hit an IRI Target value. SurPRO not only gets the profile—it also helps you find solutions to roughness problems
Built in programmable digital filters (3rd Order Butterworth) and moving average filters
Prints profile and roughness information on-site using mobile printer[3] 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 Road Uses
Management and maintenance of any road surface
Acquisition of new pavement 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 Smoothness Module)
Calibration site establishment
Equipment performance verification
Description of Typical Road 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
