Requirement Management for the 3D Pavement Model Over the Lifecycle

This article addresses the structuring of data relating to the pavement that form a part of road infrastructure, and its development throughout a project lifecycle. Modelling of the information necessary for pavement design, construction, operation, servicing and maintenance is proposed. The defined data model is accompanied by a representation of exchanges between actors and of the key processes for management of requirements with product lifecycle management tools. In this use case, the use of a digital model in infrastructure life-cycle management is addressed via the pavement component, with the aims of defining a complete information model associated with pavement, by identifying and structuring the data exchanged between the different actors and in the different project phases. These are represented by the processes within which these exchanges, bringing out the different viewpoints of the actors involved: owners, designers, builders, operators, etc.
