Abstract: In order to represent the behavior of asphalt concrete mixtures during fatigue tests, a phenomenological model based on the continuous damage theory has been developed. From this model, a method for estimation of fatigue ...

Abstract: Fatigue laws obtained by means of laboratory tests do not usually take into account the fact that asphalt mixtures in highways have rest periods (without loads). These rest periods tend to increase the fatigue life of ...

Abstract: Safety barriers limit the severe consequences to occupants of vehicles leaving the roadway from colliding with obstacles, yet they may significantly reduce the available sight distance (ASD). A procedure was devised to ...

Abstract: A critical factor in highway design is maintaining a good consistency with a road geometry that fits the drivers’ expectations. Presently, highway geometric design consistency is usually evaluated on the basis of operating-speed ...

Abstract: Analyzing the distance visible to a driver on a highway is important for traffic safety, especially in manoeuvres such as emergency stops, when passing another vehicle, or when vehicles cross at intersections. Software ...

Abstract: Safety in highway geometric design is one of the main goals to be achieved. However, deterministic design criteria do not provide information concerning the risk associated with the design outputs proposed. To yield ...

Abstract: Although geographic information systems (GISs) have been applied in different areas of transportation, full use of their potential in speed profile analysis and highway design consistency studies has yet to be made. The ...
