Description

This module examines aspects of geotechnical engineering and drainage systems related to road maintenance engineering.

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Create a specification for, and evaluate the findings of, a site investigation.

2.

Appraise the suitability of materials and construction methods used in earthworks.

3.

Identify potential geotechnical engineering issues associated with road embankments.

4.

Define, quantify and formulate the hydrological cycle, surface runoff, infiltration and rainfall/runoff correlation.

5.

Carry out hydrological analysis using various techniques, predict maximum flood runoffs and design flows for natural channels, pipes and culverts. 

6.

Appraise concepts of Sustainable Urban Drainage and apply to worked examples of source and site drainage controls. 

7.

Critically evaluate concepts of groundwater flow, aquifers and groundwater contamination.

Teaching and Learning Strategies

This module will be delivered using online lectures and workshops.

Module Assessment Strategies

The geotechnical engineering aspects of this module will be assessed using continuous assessment exercises and projects. The drainage systems aspects shall be assessed using projects and final written examination.

The geotechnical engineering aspects of this module are assessed using both individual and group continuous assessment/projects. All students will sign an Assessment Charter at the start of the module which will clearly set out the role of the student, their responsibility to the project and the project group and the responsibility of other group members to support each other. The sizing the slice method of group assessment (Clelford & Hopkins, 20014) will be used to allocate marks to the individual members of the project group. A copy of this method of allocating marks will be given to the students at the start of the module.

Repeat Assessments

The repeat assessment for the geotechnical engineering and drainage systems aspects of this module will involve resubmission of failed continuous assessment exercises and projects, and specifically in the case of the Drainage section the sitting of the final written examination.

ISBN 086017591X ISBN-13 9780860175919

Cuttings perform an important function in the efficient operation of an infrastructure network, whether it is railway, highway or waterway, and it is essential that they be recognised accordingly within the asset management policy. This book presents vital information for infrastructure owners, designers, contractors and maintenance managers. It provides guidance on the management, condition appraisal and repair of infrastructure cuttings. This guide is based on a detailed review of published literature and infrastructure owner's procedures, consultation with experts and practitioners within the field, and includes case studies demonstrating good practice. It addresses technical issues in design, repair and maintenance, and is published as an enabling document to promote the managerial and engineering requirements of infrastructure cuttings.

1997-12-15 Designing with Geosynthetics (4th Edition) Prentice Hall
ISBN 0137261756 ISBN-13 9780137261758

Still the only book on geosynthetics, this updated edition covers the latest materials and design techniques. Emphasizing design-by-function, it examines all types of geosynthetics, including geotextiles, geogrids, geonets, geomembranes, and geocomposites. KEY TOPICS: Introducing theory and techniques of chemical analysis for identifying polymer types and properties, the book covers a wide range of applications, including geotextile wall design, geogrid wall design, geomembrane side slope design, and GCL hydraulic barrier design. The book also covers geosynthetic clay lines (GCLs) and devotes an entire chapter to geopipe. It introduces design, testing, and selection of geosynthetics on a generic, rather than product-specific basis. It also provides an updated Product Reference Guide (through the Industrial fabrics Association International). The fourth edition of Designing with Geosynthetics has been revised to include the most up-to-date information as well as new examples covering transportation and geotechnical applications. An essential reference on geosynthetics for all practicing engineers.
