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 delves into Burmester's solutions for multilayer systems in road pavements, discussing analytical solutions for two and multiple layers, focusing on homogeneity, isotropy, linear and elastic behavior, and continuity equations at interfaces. The lecture also covers the use of Burmester's BAK for calculating stresses and deformations, as well as the application of software for analyzing stresses and strains in multilayer systems. The instructor emphasizes the importance of using finite element programs for better modeling of road materials, considering temperature effects, viscoelastic behavior, and load distribution. The lecture concludes by highlighting the complexity of using such programs and their application in research rather than daily design practices.

Road surface

A road surface (English), or pavement (American), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, macadam, hoggin, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course. Asphalt mixtures have been used in pavement construction since the beginning of the 20th century and are of two types: metalled (hard-surfaced) and unmetalled roads.

Road surface marking

Road surface marking is any kind of device or material that is used on a road surface in order to convey official information; they are commonly placed with road marking machines (also referred to as road marking equipment or pavement marking equipment). They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses. In some countries and areas (France, Italy, Czech Republic, Slovakia etc.), road markings are conceived as horizontal traffic signs, as opposed to vertical traffic signs placed on posts.

Road

A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads.

Price elasticity of demand

A good's price elasticity of demand (, PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good, but it falls more for some than for others. The price elasticity gives the percentage change in quantity demanded when there is a one percent increase in price, holding everything else constant. If the elasticity is −2, that means a one percent price rise leads to a two percent decline in quantity demanded.

Road debris

Road debris, a form of road hazard, is debris on or off a road. Road debris includes substances, materials, and objects that are foreign to the normal roadway environment. Debris may be produced by vehicular or non-vehicular sources, but in all cases it is considered litter, a form of solid waste. Debris may tend to collect in areas where vehicles do not drive, such as on the edges (shoulder), around traffic islands, and junctions. Road spray or tire kickup is road debris (usually liquid water) that has been kicked up, pushed out, or sprayed out from a tire.
