Overlay & Widening

Duration: One Day

Summary

This course takes the user through a typical overlay and widening civil design project. The analysis is carried out using variable depths and crossfalls, design surface triangulation and depth isopach comparisons.

The project utilises a compilation of overlay and full road reconstruction and their associated subgrade design requirements

Prerequisites:

For experienced 12d Model users only. Completion of 2 day Civil Design course and Advanced Civil Design course is essential.

Course Content:

• Introduction to Overlay Concepts.
  • setting up the data required
  • getting familiar with Overlay Panel and terminology
  • looking at outputs such as spreadsheets and plots
• Creating Design Surface
  • by initial analysis of existing surface to locate areas of superelevation, good and substandard crossfalls
  • refining design to optimise balance of materials used, scarification and design standards
• Generating Pavement Design
  • by defining subgrade and intermediate pavement layers
  • applying new techniques to locate critical
  • points for the pavement construction
• Automating Re-work
