Investigation of Laser Systems Used in Pavement Management Systems (PMS)

The surface layer of road pavement has a particular importance in relation to the satisfaction of the primary demands of locomotion, such as security and eco-compatibility. In order to reduce road maintenance and rehabilitation costs and optimize the service condition of road networks, pavementmanagement systems (PMS) need reliable and detailed data on the status of the highway network. Laser scanners can be used in an innovative way to obtain information on a real surface layer through a single measurement, with data representativeness and homogeneity. With the advancement of 3D sensors andinformation technology, high-resolution, high-speed 3D line laser imaging devices has become available for pavement surface condition data collection. This paper presents some of the key developments in recent years for laser systems automating pavement distress measurement and evaluation. These new systems are described in terms of their potential and applicability
