Course Description

Explore CIRCLY with the specialists behind the software.

For pavement engineers, designers, consultants, road authorities, contractors and heavy-infrastructure professionals, CIRCLY is essential for turning complex traffic, material and pavement data into informed, defensible design decisions.

This predominantly online, self-paced course gives you the flexibility to learn when and where it suits you. You will develop the skills to model pavement behaviour, assess performance, refine layer thicknesses and compare design alternatives with greater confidence and efficiency.

Your learning is reinforced through a scheduled 60-minute live Q&A session with NTRO’s CIRCLY subject-matter experts. This is your opportunity to have the experts “in the room” – ask detailed questions, test your understanding and draw directly on their deep technical and practical experience.

Developed and owned by NTRO, CIRCLY brings together decades of pavement engineering expertise. Learn directly from the specialists behind the software and discover how to apply its capabilities to real-world pavement design challenges.

Enrol now to learn at your own pace – and gain direct access to the experts behind CIRCLY.

Course structure

Engineering foundations – understand the design principles and performance models behind CIRCLY.
Core software workflow – create materials, loads and layered systems, then analyse and refine designs.
Optimisation and rehabilitation – compare cost and performance while exploring treatment alternatives.
Advanced applications – evaluate heavy-duty pavements, haul roads and specialised vehicle loading.

Learning outcomes

By the end of this course, participants will be able to:

Explain the principles of mechanistic-empirical pavement design.
Interpret traffic loading, axle groups and traffic load distributions.
Define project reliability and assess its influence on pavement design.
Create and manage material properties within CIRCLY 7.
Build layered pavement systems for different design applications.
Configure and run pavement design and general analysis workflows.
Interpret stresses, strains, displacements and Cumulative Damage Factors.
Identify the material, layer or distress mode controlling pavement performance.
Use automatic thickness design and parametric analysis to refine designs.
Compare pavement alternatives using performance and cost information.
Model rehabilitation treatments, specialised vehicles and haul-road loading.
Apply current guidance, local requirements and engineering judgment when interpreting CIRCLY results.
