Municipal Pavement Design and Construction in Western Canada

After participating in this course, you will be able to:

• Apply practical knowledge to effectively rehabilitate municipal roadways.
• Understand the fundamental parameters necessary for completing pavement designs.
• Select the most suitable pavement type and rehabilitation strategy by evaluating relevant factors.
• Identify various pavement distresses and determine the appropriate treatments based on current best practices.
• Utilize your comprehension of specification requirements to conduct thorough and accurate field inspections.

Description
Focusing on the complexities of pavement design and construction in densely populated urban areas, this course emphasizes the necessity for engineers to consider various factors such as curbs, gutters, utilities, and private and commercial entrances during the planning and execution of pavement projects. Effective pavement engineers must have a comprehensive understanding of roadway design constraints to select the most appropriate and cost-effective pavement rehabilitation treatments. These treatments should also be adaptable to future needs, ensuring the long-term sustainability and functionality of urban infrastructure.

This course covers a wide range of pavement rehabilitation strategies and provides guidance on selecting the best options for specific project requirements. Additionally, it offers insights into designing and constructing new pavements using flexible, rigid, and composite pavement types. Participants will learn to understand critical construction specifications and identify key features to monitor during inspections to ensure quality and compliance.

While encompassing concepts applicable across all Canadian jurisdictions, this course includes specific references and examples from municipalities in Western Canadian Provinces. By the end of this course, participants will be equipped with the knowledge and skills to tackle the unique challenges of urban pavement projects, enabling them to make informed decisions that balance cost, effectiveness, and future needs.

Who Should Attend
This course will be particularly valuable for professionals involved in the assessment, design, and construction of municipal roadways. These include pavement engineers, civil technicians and technologists, engineering consultants, design engineers, construction inspectors, and contractor superintendents.

Whether you are directly engaged in roadway projects or provide support through consultancy and inspection, this course offers critical insights and skills to enhance your expertise and effectiveness in urban pavement design and construction.
