The model of a road or a street design includes the context information, base data and route plan described in chapters 1-3. In addition, it contains the physical elements of the road structure:
IfcReinforcedSoil can be used to represent natural soil reinforced by or stabilized by some mechanical or chemical method. It may have its top surface definition as IfcShapeRepresentation having RepresentationIdentifier 'Body' and RepresentationType 'Tessellation', with IfcTriangulatedIrregularNetwork as Items that represent the geometry.
IfcReinforcedSoil may have codings associated as IfcClassificationReference and properties (standard or custom) as IfcPopertySet.
IfcEarthworksFill is a element created by earthwork activities to build subgrade or to raise the level of the ground in general. Subgrade element forming the structure below pavement and above natural soil

IfcPavement is a type of built element in a road or other paved area to provide an even surface sustaining loads from vehicles or pedestrians, usually comprising several courses
IfcShapeRepresentation represents the concept of a particular geometric representation of a product or a product component within a specific geometric representation context. The inherited attribute RepresentationType is used to define the geometric model used for the shape representation, the inherited attribute RepresentationIdentifier is used to denote the part of the representation captured by the IfcShapeRepresentation (e.g. Axis, Body, etc.).

IfcCourse is a built element whose length greatly exceeds its thickness and often also its width, usually of a single material laid on site on top of another horizontal or nearly horizontal built element. A course is distinctive from a earthworks element in that a course is a graded granular (which can be bound or unbound) material that is generally processed in some fashion, where as earthworks elements are soil earthen based structure that can be formed by removal and transport of general ground material. Structurally a course does not have capacity to carry loads over open span, or to be removed or replaced as a single unit. examples of courses include: • Graded aggregate layers • Graded sand layers • Cement bounded material (CBM) • Asphalt layers
