Learning Objectives

Upon successful completion of the course, students will be able to:

  1. Perceive the inter-scientific character of road works.
  2. Understand the number and content of the bill of quantities to be taken into account in the costing of road projects.
  3. Precisely define the details of unit quantities.
  4. Cost road projects (tasks completed by the road engineer, as well as approximate estimation of the remaining ones).
  5. Know basic road cross-sections and related specifications.
  6. Comprehend general principles of road design, analysis and distress.
  7. Know general road construction materials.
