Aim
The aim of the course is to provide the student with national and international knowledge about management and maintenance of the roads and streets. Important areas such as evaluation of bearing capacity, different material control methods to document the deterioration of the pavements are discussed. The subject of Pavement Management Systems is deeply studied in the course

Knowledge and understanding
For a passing grade the student must

· Describe how various technical aids for determining the condition of the pavement (laser measuring vehicle, falling weight deflectometer and georadar) can be used for maintenance planning

· Explain the principles for prioritising among different objects for winter road maintenance

· Understand the effects of water on deterioration of the pavements

· Analyse and understand the mechanism behind deterioration of the pavements

· Understand the effects of traffic on different pavement deterioration

· Describe differences between management and maintenance of the roads

Skills and abilities
For a passing grade the student must

· Develop and apply a Pavement Management System on object level in order to choose optimal, cost-effective maintenance strategies based on national economic grounds

· Motivate and discuss different maintenance strategies and their economic consequences

· Carry out visual distress surveying according to the “sink or swim” principle

Judgement and approach
For a passing grade the student must

Understand importance of systemically management and analyse information that is used in maintenance planning and evaluate the reliability of the results based on accessible information.
