Road Construction
Course Description:
Introduction to road construction issues and the related construction materials (soil materials, aggregates, asphalt materials, asphalt mixes). Aspects of road stress-strain state and basic principles of pavement analysis. Determination of fundamental properties of individual materials, quality control and suitability assessment of materials. Aspects of design and other construction issues of pavement foundation and other individual layers of the pavement structure.
