3. Aim
To study the use of Lasers in measuring the cracks in the pavements as
well as to study the Road Profiling and its parameters.

4. Objectives
1. To measure the crack developed in concrete using laser scanner
mounted on a vehicle.
2. Understanding the advantages of the LCMS on Road Profiling ,
Speed Checkers, Pavement Deflections.
3. Pavement Condition Assessment Using Laser Crack Measurement
System (LCMS) on Airfield Pavements

5. Introduction
• The deterioration of structures due to reinforcement corrosion is a
major problem globally. The corrosion of the reinforcement can lead to
rust staining, cracking spalling, and eventually structural failure if no
remedial action is taken.
• In order to assess the condition of a pavement a visual inspection is
often the first step, with any defects identified.
• The laser crack measurement system (LCMS) uses laser line
projectors, high speed cameras and advanced optics to acquire high
resolution 3D profiles of the road.
