CSL-90 Portable LiDAR Survey Profiler
Full Lane Width Scans with a Solid-State LiDAR System, Including AASHTO Compliant IRI Measurement
Products Brochure
At A Glance
The CSL-90 can be paired with any of the SSI software or sensors including: ROW cameras, inertial profiler sensors, and macrotexture measurement. The LiDAR sensor can report IRI profiles accurate enough to pass the AASHTO certifications, but sensors can be added for full compliance. At highway speeds near 50 mph the LiDAR sensor can collect less than a 1-inch x 1-inch grid (25mm x 25mm).
Highlights of the CSL-90:
- Collect Survey Data in One Pass per Lane
- 4-meter wide (13.1-foot) Scan Width with Solid State LiDAR sensor
- 0.45mm Accuracy on 28,000 LiDAR Beams
- Report IRI from LiDAR Point Cloud or Inertial Profiler Sensors
- AASHTO and ASTM Compliant Inertial Profiler
- Tight Sampling Interval at Highway Speeds
- Zero-Speed Inertial Profiler Capable
- Portable Setup, Factory Calibrated
The CSL-90 Portable LiDAR Survey Profiler is an adaptation of the CS9500 family of survey profilers. With improved sensor capabilities, the CSL-90 captures the full lane width with a single LiDAR sensor. All of the features of a full lane scanner remain within the CSL-90’s smaller footprint.
The CSL-90 can include a single, dual or three track high-speed inertial profiling system for AASHTO and FAA compliant smoothness testing. This platform can also be upgraded to a Zero-Speed Inertial Profiler. As a single track profiler unit, the CSL-90 is ideal for airfield survey and smoothness testing. The CSL-90 can report an IRI or PRI value through the SSI software.
Once overlapping scan data is collected, a 2D or 3D point cloud surface can be created within SSI software. This point cloud can be exported into SSI’s Profile Design or another design software.
The CSL-90 hardware and software core features:
- Portable setup, mounts to hitch receiver. Ships and stores in a custom foam case.
- Single, dual, or three track inertial profiler (AASHTO R56-57, ASTM E950) integrated within system and simultaneously collects profile data
- 4-meter (13.1-foot) wide scans
- Collect data at highway speeds
- SSI CAD program to merge control points into dataset for secondary correction
- Intensity displays lane lines and delineation
- Scalable: Start with CSL-90 for LiDAR point clouds and upgrade an integrated inertial profiler at any time.
- SSI software merges elevation correction points for precise 3D elevations
- Outputs data in common formats (e.g.) PNEZD, PLLHD, GPGGA, and LAS
All-In-One Design
The CSL-90 LiDAR Survey system can report IRI from the LiDAR unit or by using an integrated inertial profiler. The CSL-90 reports IRI, PRI, HRI, RMS, RN (longitudinal profile), transverse profile, and 2D/3D surface scans for land surveying and machine control applications.
2D+ or 3D Capable Models
The CSL-90 system can also be used for 2D scanning for pavement rehabilitation work that does not involve paving to 3D elevations. This is typically known as differential milling or paving.
SSI’s software includes a Profile Design module for configuring slope and cut/fill parameters for a design output optimized for best IRI results. The resulting model can be imported to machine control systems, including 2D or 3D grade control systems.
