CIVIL-463: Design and construction of roadways

Ce cours permet de maîtriser les principes et les bases de la conception des voies de circulation (infrastructures routières et ferroviaires). Il traite les bases des projets, la géométrie, la sécurité routière, les matériaux utilisés, les techniques de co ...

Description

This lecture covers the properties and types of bitumen, including the diagram of Colombo, standard bitumen values, and the complex modulus. It also discusses bitumen modifications, such as emulsions and cutbacks, and the importance of porous asphalt for noise reduction. The lecture delves into the composition of bituminous mixtures, the role of aggregates and binders, and the optimization process. Additionally, it explores the impact of traffic, climate, and material aging on road performance, emphasizing the need for structural integrity, functionality, and environmental considerations in pavement design.

Traffic collision

A traffic collision, also called a motor vehicle collision (car crash in case cars are involved in the collision), occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved.

Traffic flow

In mathematics and transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.

Road traffic safety

Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams). Best practices in modern road safety strategy: The basic strategy of a Safe System approach is to ensure that in the event of a crash, the impact energies remain below the threshold likely to produce either death or serious injury.

Active noise control

Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in commercial airline headsets with the technology becoming available in the late 1980s. The technology is also used in road vehicles, mobile telephones, earbuds, and headphones.

Highway engineering

Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway engineering became prominent towards the latter half of the 20th century after World War II.
