Abstract
The present lecture handout is intended for students enrolled in the second year of the Master's degree in civil engineering, more specifically in civil and industrial construction specialization. The course deals with the design and dimensioning of road projects, and more specifically pavements and roadways. After the achievement of the course, students will be introduced to roads infrastructures design and management. Indeed, it is to point out that learners need the recommended foundational knowledge and concepts especially in soil mechanics, construction materials, and physics.
Road pavements can be defined as the part of a transportation route dedicated to vehicle traffic. Roadways are composed of multilayer structures implemented on a foundation known as the pavement support platform. A pavement is essentially designed to resist the mechanical actions of vehicles and transfer these loads to the underlying foundation soil without causing permanent deformations in either the soil or the pavement. Through these chapters, the lecture aims to achieve few objectives to provide knowledge and tools for the following issues:
An overview of road systems to understand why we built roadways and their crucial role in the development of civilizations. To better understand its technical aspects in a historical context, one must embrace project management principles and grasp the social and economic issues surrounding this field.
Master skills on vehicle kinematics and pavement method design to better understand how vehicles move through space, taking into account the various parameters that influence their movement. In addition, to involve comprehension in selecting the necessary materials with the required properties and determining the thicknesses of the various layers in the pavement structure.
Geometric features of traffic lane roads which were defined in a spatial design by the plan alignment, the longitudinal profile and the cross profile. The geometric characteristics of these elements must correspond to the most cost-effective solution and ensure certain minimum conditions defined by the natural environment, particularly the topography, geology and the anticipated future traffic.
Earthworks in road construction to shape the foundation and the platform that will support the pavement and associated equipment. This shaping involves operations to alter the topography of a site to provide the road with the geometric characteristics specified according to the execution and design plans.
The objectives outlined in this educational document helps to understand the key factors in the design and management of a communication route project. In the context of allowing students to gain a deep understanding of the concepts in the roadways transportation planning, an exhaustive set of references with very high scientific and educational quality is presented at the end of the document.
