Runway Application
Surpro was designed to measure runways and contains several features to make runway data collection faster, safer and more accurate. For runway 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 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).
  • 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 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 Runway Uses
  • Management and maintenance of any runway 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.
Analysis and Reports
  • Road analysis, including IRI, RN, PRI or PI can be performed on runways as well.
  • 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.
  • Boeing Runway Roughness Criteria Analysis Module support:
  • Graphical report identifying each bump and showing start and end; length; height; recommended grind start, end and depth.
  • Boeing Roughness Criteria for Isolated Bumps scatter graph plotting each bump according to height and length to determine if it is Acceptable, Undesirable or Temporarily Acceptable (also Acceptable after 1995), Excessive or Unacceptable.
  • Tabular report showing bump start and end; length, height; recommended grind start, end and minimum depth to achieve user specified criteria line (Acceptable, Undesirable or Temporarily Acceptable (also Acceptable after 1995), Excessive or Unacceptable) with minimum grinding or filling. Detailed multiple pass grinding plan.
Taking Corrective Action to Restore Smoothness
Bumps classified in each of the four roughness categories shown on the chart may be interpreted as follows.
  • "Acceptable" - Bump height/length combinations falling in this region should not adversely affect the majority of aircraft operations.
  • "Undesirable or Temporarily Acceptable" - Bumps in this category may be experienced as rough by certain but not necessarily all aircraft. In this region, many variables will determine the roughness response of an aircraft to the bump including the location of the bump in the aircraft's takeoff/landing run, the aircraft operating speed, the aircraft ground-borne mass when the bump is encountered and the shock absorption properties of the aircraft landing gear. Depending on the nature of the bump, corrective action should be undertaken whenever feasible to reduce the bump height/length ratio into the "acceptable" category.
  • "Excessive" - Most classes of turbojet aircraft will experience objectionable roughness when operating over bumps of this magnitude regardless of the other variables that influence roughness response as described in Section 2 above. Aircraft manufacturers may recommend and airlines may consider the suspension of aircraft operations on surfaces containing bumps of "Excessive" magnitude. Bumps in the "Excessive" category should be corrected immediately.
  • "Unacceptable" - Bumps in this category will be found objectionable by all aircraft and should either be corrected immediately or operations over such bumps suspended.
Surpro identifies the recommended grind start, end and minimum depth to achieve user specified criteria line (Acceptable, Undesirable or Temporarily Acceptable (also Acceptable after 1995), Excessive or Unacceptable) Corrective action for isolated bumps may take the form of general resurfacing overlays if the roughness is extensive throughout the pavement, leveling of depressed areas or surface grinding to remove material creating the objectionable bump.
