ENG08012 2019 Highway Engineering 402H
This module examines the environmental impact and economic implications of highway route options and explores components of highway design such the determination of route capacity, the design of intersections and the structural design of pavements. Pavement maintenance is also addressed.
Learning Outcomes
On completion of this module the learner will/should be able to;
Apply scientific, engineering and mathematical techniques to the evaluation of rural highway capacity with respect to
space mean speed, traffic density and traffic flow/capacity.
Identify and apply appropriate environmental and economic assessment techniques for the appraisal of highway projects.
Design highway intersections and evaluate their operational characteristics.
Classify and evaluate the behaviour/properties of materials and identify and apply appropriate methodologies for the structural design and rehabilitation of road pavements, both flexible and rigid.
Perform in teams in the design and assessment of intersections.
Teaching and Learning Strategies
Delivery of material by formal lecture, supplemented by practical classes, and augmented by independent learning. The practicals enable learners to apply the theory in project work.
Module Assessment Strategies
A mix of final semester examination (70%) and practical design/analysis and report work (30%).
An overall pass mark of 40% must be obtained to pass the module.
Repeat Assessments
Learners shall repeat the failed elements. The leaner must then achieve an overall mark of 40% to pass the module.
