The ROMDAS system itself comprises of the central components and software licences that allow for data acquisition and analysis. The next step, is then choosing the add-on modules you require based on the type of data you require and level of accuracy

Systems - Tailored Design ROMDAS System Bump Integrator (Roughness – unpaved roads) High Res DMI (Distance/Chainage) GPS Receiver (capable of sub-meter DGPS) LCMS with Roughness + Geometry upgrades Multiple ROW cameras Computer system, power supplies and all other required accessories The configuration we have offered in the past includes these items; ROMDAS System – Central hardware and software which all modules are connected to an synced. Bump Integrator (Roughness – unpaved roads) – used for collecting roughness data on rough/unpaved/wet roads where laser equipment has the potential of being damaged or compromised accuracy. High Res DMI (Distance/Chainage) – HRDMI – required for the 1mm distance accuracy required for laser data collection. Collected around 12,000 pulses per revolution of the tire. GPS Receiver (capable of sub-meter DGPS) – Trimble SPS461 – If the client purchases Omnistar subscriptions for their GPS receivers then they will collect sub-meter GPS coordinates in real-time. We have validated the SPS461 in India for another client and found it had an average accuracy of 0.4m (when connected to Omnistar signal). All data can then be referenced to GPS coordinates. LCMS with Roughness + Geometry upgrades. See following slides for LCMS outputs. Multiple ROW cameras – 3 x cameras per system. Output max resolution of 1600x1200 from each camera. Videos can be simultaneously viewed and rated in the office using ROMDAS DataView software. Computer, power supplies and all other required accessories

ROMDAS LCMS collects Automatic crack and defect detection and analysis including; cracking (width, length, depth), potholes and raveling/joint data, sealed crack detection. Pavement Images Transverse Profiles Rut Depth, Width & Cross-Sectional Area for each wheelpath, Macro-Texture (MPD) in 5 bands across the whole lane width, Optional Upgrade: Roughness (IRI) Geometry FOD Detection (Airports) Ravelling Joint/Faulting Cracking & Defects The ROMDAS Laser Crack Measurement System (LCMS) uses laser line projectors, high speed cameras and advanced optics to acquire high resolution 3D profiles of the road. The LCMS can acquire full 4 m width profiles of a highway lane at normal traffic speeds. The system uses two scanning laser profilers that digitize transverse sections of the pavement. Custom optics and high-power pulsed laser line projectors allow the system to operate in full daylight or in night-time conditions Using the profiles collected the system can accurately calculate the degree of pavement rutting and overcomes many of the drawbacks of other rut measurement systems that use less contact points and transverse range. Thanks to the exceptional speed of the scanning lasers, users of the ROMDAS LCMS are able to collect information on surface texture properties in terms of Mean Profile Depth (MPD). The LCMS offers great flexibility by providing optional upgrades. The LCMS can be expanded to collect Roughness (IRI) data by attaching sensitive IMUs. Using the same IMU’s as the roughness upgrade the LCMS is also able to output a variety of road geometry datasets, including Grade (%), Horizontal curvature (m) and Cross-slope (%).

ROMDAS LCMS Standards ASTM E950; Can collect longitudinal profile and compute IRI ASTM E1845; Can collect macro texture and compute MPD ASTM E965; Can collect macro texture and compute MTD ASTM E1703; Can compute rutting according to standard AASHTO PP67; Can quantify cracking AASHTO PP68; Can collect images of pavement surfaces AASHTO PP69; Can determine pavement deformations AASHTO PP70; Can collect transverse profiles Ravelling Joint/Faulting Cracking & Defects

ROMDAS LCMS Features Survey Speed 0 – 100km/h. Conforms to IP-65 (NEMA 4). Operates at 5,600 Hz (Profiles per second). 4 m profile width. Laser imagery allows for data collection in day or night conditions. Outputs generic MS Access (.mdb) files for raw data, as well as JPEG images which show the quantity and severity of defects at 10m intervals. The LCMS accurately measures the transverse profile across the full lane width up to 4m with the equivalent of 4096 points transversely which are used to calculate rut depth. The high frequency of transverse profiles (5,600 profiles per second) also allows the LCMS to measure other datasets like macro-texture (MPD), cracking/potholes and Ravelling/Joint Data. Optional upgrades are available which include collection of longitudinal profile (i.e. roughness – IRI) and road geometry.

Special Features Scanning Laser; accurately measures the transverse profile across the full lane width. Macro-texture Measurement; can be measured over whole pavement. Lane tracking; eliminates data variability and inaccuracies due to vehicle wander ‘year-on-year’. Roof Mounted Equipment; mounted 2.2 m above pavement surface, at rear of vehicle. Roughness Inertial Measuring Unit (IMU); instead of traditional accelerometers. Validation tool; unique tool which validates the calibration. Laser based pavement imaging; automated defect detection, lane marking detection, high quality pavement images (with optional defect overlay). There are several unique features to this system which significantly enhance the data reliability and accuracy over other traditional data collection systems. This type of equipment represents where the industry is heading and offers great future proofing. See “LCMS Special Features” document on the ROMDAS website for full explanations.

Benefits of using the LCMS Very high accuracy data making it perfect for analysis of major highways, High operating speed (up to 100km/h), Wide variety of data collected, Identification of lane markings mean the unit can automatically adjust the position of data (like MPD bands and Roughness) to match user-defined locations. In turn giving increased accuracy (i.e. removes the influence of the driver on the collection of data), Raw data profiles are recorded allowing for re-processing using different parameters. Real time status provided to operators

Operation Principle Data Collection: Real-Time Status Display High accuracy pavement profiles Real-Time Status Display Real-time status display. Giving operators immediate feedback on correct operation of system. Real-time status of LCMS are displayed during the survey and raw data is automatically saved by the ROMDAS system allowing for further analysis and calculations based on raw data. The ROMDAS software does not require any operator interaction during LCMS data collection. Post-Processing Pavement Analysis Outputs a wide variety of pavement analysis data used in deterioration modeling and maintenance planning

The LCMS Measures Every mm Of The Roads Surface The LCMS has a variety of advantages and benefits that far exceed traditional multifunctional data collection devices. The high powered scanning lasers are capable of profiling every millimetre on the road surface and identifying a wide variety of pavement characteristics.

What Makes 3D Sensors Perfect For Crack Detection? Excellent 3D accuracy (0.5mm), Good lateral resolution (1mm), High acquisition rate (5,600 profiles/s),  45 million 3D and 2D points/s

Lane Tracking LANE MARKINGS are used to correct profiles and compensate for driver wander Simplifies certification procedures Eliminates the need to certify operators A key advantage to using the LCMS system is the ability for data sets to be referenced to the lane markings and curb positions instead of the vehicle’s driving line which will vary from year to year. This unique feature can be used when calculating the wheelpath and lane roughness, Macrotexture Measurement and rutting scan width.

Macro Texture Network survey is possible at 100kmh Full lane width is measured 5 AASHTO bands Great repeatability Automatic lane marking detection The LCMS is unique in that with the very high transversal scan rate of the laser the Macro texture can be calculated for all parts of the complete pavement area. The LCMS reports the Mean Profile depth (MPD) macro texture and / or Road Porosity Index (RPI) in 5 adjustable width longitudinal bands across the whole lane width (the 5 AASHTO bands are: central band, two wheel path bands, and two outside bands).

Transverse Profiles and Rutting Most accurate transverse profiler on the market with 4,000+ points per profile Calculate Rut Depth, Rut Width and Cross Sectional Area or wheel path depressions. Traditional Transverse Profilers only collect around 7-24 points per transverse profile meaning they can potentially miss high and low points.
