Specific Learning Outcomes

Field data reduction

-coordinate calculation and traverse plotting

- centerline profile plotting

-cross sections

 

Roadway design procedures

-that satisfy low volume criteria and consider environmental, user, maintenance and economic constraints.

 

Independent use of design tables and aids, standards and specifications.

 

Design stationing including circular horizontal curves

 

Effective use of grades and vertical curves that consider both user and erosion criteria

 

Safety and driveability concerns

-turnouts and turnarounds

-sight distance

-recreation user

 

End areas and earthwork quantity computation

-Mass diagram

           + development, balancing and analysis

           + use as a design tool to increase the economic efficiency and design effectiveness

-Hydraulic design

            + drainage and ditches

            + determination of culvert sizes

            + optimum use of grades and vertical curves for effective drainage and erosion control

 

Costs

          -preparing preliminary cost estimates using a regional cost guide

          -(participants may bring and use their organization's cost guide)

 

Introduction to

          -soil materials applicable to road design

         -native materials surfacing applications

 

Class Design Project:

 

The core of this course is a comprehensive design project completed by each participant.

The project gives each participant the opportunity to try out newly acquired skills. Participants are encouraged to consider the project to be within their home area, particularly hydrologic, vegetation and similar characteristics. Participants are encouraged to explore and experiment with the design techniques, finding those that work in some situations and those that work in others.

 

Each participant is individually evaluated in a private, non-threatening review.

The review is based on the participant's understanding of design principles and constructive effort, not entirely on the final design's efficiency or effectiveness.

 

A brief written report is prepared for each participant by the instructors. The report is provided only to the participant and his/her immediate supervisor.

It outlines the individual's strengths and limitations with regard to road design. This is considered preferable to a letter or number "grade."
