This course covers the latest methods and procedures to address the geotechnical issues in pavement design, construction and performance for new construction, reconstruction and pavement rehabilitation projects.
- Course Outline
After participating in this course, you will be able to:
• discover issues and challenges associated with the design and construction of modern pavement system
• explain the geotechnical parameters of interest in pavement design and their effect on the performance of
different types of pavements
• appreciate the influence of climate, moisture, and drainage on pavement performance
• recognize and take into consideration the impact of unsuitable subgrades on pavement performance
• determine the geotechnical inputs needed for design of pavements
• evaluate and select appropriate remediation measures for pavement subgrades
• specify geotechnical aspects of construction and inspection requirements
• identify subgrade problems during construction and develop suitable solutions
• conduct adequate subsurface exploration and laboratory characterization of subgrade soils, the requisite
design parameters for unbound base layers and the drainage in relation to pavement design
• perform the necessary steps to develop and complete the design procedures of asphalt system including the
utilization of geosynthetics within the pavement structure
This course covers the latest methods and procedures to address the geotechnical issues in pavement design, construction and performance for new construction, reconstruction and pavement rehabilitation projects. The course content includes geotechnical exploration and characterization of in-place and constructed subgrades; designing and constructing pavement subgrades and unbounded materials for paved and unpaved roads. The course also presents the HMA design methods including SuperPave and Hveem in addition it emphasizes the structural design methods of pavement structures based on the current AASHTO 1993 design guidelines. The course is designed to give in-depth knowledge on the mechanistic-empirical design approach, including the three levels of design inputs; the overall geotechnical and drainage aspects of bases, subbases and subgrades (for a safe, cost-effective, and durable pavement); and construction and inspection of pavement projects. This is an interactive course in which participants will gain an understanding of the impact of geotechnical features on the long-term performance of pavement systems.
The main objectives of this course are to provide participants with an understanding of the essential importance of the geotechnical aspects
relevant to the design, construction, and performance of a pavement system and to appreciate the significance of the recent advances in the field.
Who Should Attend
Civil engineers, managers, owners of highways , Ministry of Transportation personnel , pavement design engineers, transit system engineers, infrastructure project managers, geotechnical engineers, consulting engineers, specification writers, quality assurance managers, construction engineers and technicians and technologists involved in the design, evaluation, construction, reconstruction or rehabilitation of pavements.
You will receive free copy of the following software: SpectraPave 4™ Software, incorporates AASHTO ‘93, Tensar® and Giroud-Han technology - the state-of-practice design methodologies for both flexible pavements and unpaved roads. This interactive software can be used for the analysis of both reinforced and unreinforced structures. A workshop for design examples will be conducted under instructor guidance.
Participants should bring their laptops to the class.

A. O. Abd El Halim
Dr. A.O. Abd El Halim, Chair of the Department was just awarded the 2005 Sandford Fleming Award by the Canadian Society for Civil Engineering (CSCE) for his remarkable contributions to the development and practice of transportation engineering in Canada. The award was presented on June 3 at the 2005 Awards Banquet hosted by the CSCE at the Westin Harbour Castle Hotel in Toronto. He is a well known keynote speaker, reviewer, and the member of several important committees having been named the 1999 Top Newsmaker by the USA magazine, Engineering News Record. He also won the NOVA award by the Construction Innovation Forum, the Nobel prize for construction innovation, making him the first civil engineer to receive both awards in the same year. In recognition of his achievements, Professor El Halim was elected a Fellow to the CSCE in 1998.
