چکیده

In order to maximize road maintenance funds and optimize the condition of road networks, pavement management systems need detailed and reliable data on the status of the road network. To date, reliable crack and raveling data has proven difficult and expensive to obtain. To solve this problem, over the last 10 years[1][2] Pavemetrics inc. in collaboration with INO (National Optics Institute of Canada) and the MTQ (Ministère des Transports du Québec) have been developing and testing a new 3D technology called the LCMS (Laser Crack Measurement System). The LCMS system was tested at the network level to evaluate the system’s performance at the task of automatic detection and classification of cracks. The system was compared to manual results over 9000 km to be 95% correct in the general classification of cracks.

High Performance 3D Sensors for the Characterization of Road Surface Defects

Two different optical configurations were developed and are described. The first is a laser profiling system that is used for transverse profile acquisition for rut detection purposes. The second uses an autosynchronized laser scanning sensor for crack detection Both these systems have been installed on inspection vehicles and have been tested. Tests have shown results that have a very good cor...

The Effect of Asphalt Concrete Micro & Macro Texture on Skid Resistance

Skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. The surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. During the study, the mean texture depth of the road surface was measured, in order to determine the co...

Three-dimensional laser ranging image reconstruction using three-line laser sensors and fuzzy methods

This paper describes the analysis and identification of road surfaces three dimensional distress characteristics by means of a three-line laser sensor. A laser-based vehicle-mounted imaging system simultaneously evaluates several conditions of road surface distress, such as ruts, cracks, and surface roughness. The three-dimensional feature extraction is done by a combination of two measuring te...

Laser Scanning on Road Pavements: A New Approach for Characterizing Surface Texture

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. Among those pavement surface characteristics, the "texture" appears to be one of the most interesting with regard to the attainment of skid resistance. Specifications and regulations, providing a wide range of functional ind...
