This paper discusses the methodology used to determine type, severity, extent and aggregation of LCMS distress data. LCMS data has replaced a visual assessment method for identifying cracking and other surface distresses.

Slope, Cross Fall and Super Elevation (optional)ĭeveloping a Surface Condition Indicator from Laser Crack Measuring System Data for Pavement Asset ManagementĪuthor: Aziz Salifu and Nichole Andre (Saskatchewan Ministry of Highways and Transportation)Ībstract: The Saskatchewan Ministry of Highways and Infrastructure (SMHI) adopted Laser Crack Measuring System (LCMS) technology for collecting road condition data in 2016.

Measurement of longitudinal profile and calculation of roughness (optional).

GPS tagging of measurements and images (using Customer-supplied GPS).

Pavement marking detection and dimension measurement.

Pavement type detection (asphalt and concrete).

Joint detection and faulting measurement.

Edge drop off and curb detection and measurement.

Sewer and storm-drain detection and inventory.

Automatic measurement of macro-texture (MPD, MTD) in all 5 AASHTO bands.

Automatic detection and measurement of raveling (an industry first).

Automatic pothole detection and measurement.

Automatic rutting measurement (compliant with ASTM E1703, Taut Wire, Moving Ruler, Brazilian method, 5 Point rut depth calculation).

Automatic detection and measurement of cracking (both sealed and unsealed).
