This unit specifies the competencies required to design basic pavement structures. It involves site visit, designing pavement structures and carrying out road geometric design. Design Roads Structures 1 is a foundational unit that introduces learners to the principles and practices involved in the planning, analysis, and design of road infrastructure. The unit focuses on the structural components of roads, including pavements, drainage systems, and supporting structures, with an emphasis on ensuring safety, durability, and cost-effectiveness. Learners will gain knowledge of material properties, traffic loading, and environmental factors that influence road design. By the end of the unit, students will be equipped with the essential skills to develop basic road structure designs that meet engineering standards and support sustainable transportation systems.
