Description

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;

1.

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.

2.

Identify and apply appropriate environmental and economic assessment techniques for the appraisal of highway projects.

3.

Design highway intersections and evaluate their operational characteristics.

4.

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.

5.

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.

 

Indicative Syllabus

  1. Highway Design Capacity. Basic relationship between speed, density and flow/capacity of a rural highway. Level of Service approach to multi-lane and single carriageway rural highway capacity and service flow prediction. Horizon year design volume prediction.
  2. Economic and environmental evaluation of highway schemes. Scheme appraisal. Cost-benefit analysis. Discounting. Legislative requirements.
  3. Intersection Design. Junction types and function. Use of design standards and guidelines. Sight distances. Junction capacity and saturation flow.  Major/minor priority junctions. Roundabouts. Signal-controlled junctions. Calculation of optimum cycle time, inter-green time, early cut-off/late start signals, and junction phasing and staging for signal-controlled urban junctions. Design of linked signal co-ordinated junctions. Grade separated junctions. Provisions for pedestrians and cyclists.
  4. Road Pavement Structure. Flexible, flexible-composite, rigid, rigid-composite pavements. Properties of road layers.
  5. Highway materials. Composition/behaviour of granular, HBM, and bituminous materials. Compaction. Testing. Recycling.
  6. Pavement Structural Design. Design criteria for flexible and rigid pavements. Empirical design methods. Analytical design methods..
  7. Highway maintenance. Distress. Skid resistance. Strengthening and rehabilitation. Surface dressings. Other surface treatments.

Indicative Practicals/Projects 

  1. Road scheme environmental appraisal project.
  2. Junction layout design/assessment .
  3. Junction operational modelling using relevant software.
