From page 99... ...
Glossary 99 Light detection and ranging (LiDAR) : A system of lasers and sensors supported by traditional cameras, GPS receivers, and DMIs used to generate 360-degree point-cloud images of the pavement and surrounding facilities that allow the identification and analysis of pavement distresses as well other facilities included in an asset management system.

100 Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports Pavement deflection: The change in pavement surface elevation to an applied load. The deflection of a pavement surface is used to calculate the structural layer stiffness and subgrade resilient modulus for a pavement.

From page 101... ...
Glossary 101 Structural capacity: The load-carrying capacity of a pavement that can be determined through an in-depth evaluation of the material layers and thickness within a pavement structure and/or through an evaluation of the surface deflections. Structural condition index (SCI)
