Engineered for efficiency: scale inspections with less hardware.
Download data sheet
One sensor, smaller footprint, easier integration.
Built for large national networks and multi-vehicle deployments.
Delivers the exact high-resolution 2D+3D data as LCMS-2.
Simpler setup means quicker rollouts and lower operating costs.
Adaptable across climates, surfaces, and large-scale inspection projects.
The Pavemetrics® Laser Crack Measurement System (LCMS®-4M) is a compact, single-sensor 3D vision system that automates pavement inspection at traffic speed. In one pass, the LCMS-4M geo-tags, measures, and quantifies all key functional parameters of pavement — including cracking, rutting, potholes, patches, markings, and road features such as manholes and drains — with the same proven precision and repeatability of the LCMS family.
Designed as an add-on for Mobile Mapping Systems, the LCMS-4M delivers a fully automated, standards-compliant workflow that outputs PMS-ready condition scores. This makes it ideal for cities, counties, and contractors who need to scale inspections across large networks without adding complexity.
With its smaller footprint, easier integration, and proven adoption in more than 45 countries worldwide, the LCMS-4M brings efficiency and reliability to pavement management — enabling proactive maintenance, longer-lasting roads, and smarter use of public funds.
100× the resolution of mobile LiDAR — with 1 mm detail across the full lane.
Compact, single-sensor add-on for MMS.
PASER score & ASTM E3303 index generated automatically.
95%+ repeatability.
High-res images and GIS-ready formats (JPEG, XML, SHP).
Automated detection: Cracking & rutting, potholes, patches, raveling, bleeding, delamination, shoving, joints & faulting, pavement markings (with dimensions), manholes & drains, rumble strips, curbs, edge drop-off, pick-out.
1 mm across full 4 m lane (100× the resolution of LiDAR).
0–100 km/h.
Single-sensor module for MMS.
Compatible with customer-supplied GNSS & DMI.
JPEG, XML, SHP (PMS-ready).
Asphalt and concrete.
LCMS-4M is built on the same LCMS platform and includes all core standards supported by LCMS-2
LCMS-4M inherits the full standards compliance of the LCMS platform (ASTM & AASHTO), while adding automated PSCI (ASTM E3303) and PASER scoring — making it uniquely suited for city and county pavement management workflows.
