Overview
Hot Mix Asphalt (HMA) is the most common paving material. As HMA is very sensitive to temperature and degradation; it must be produced, hauled, and placed within a specific period of time and without segregation. The appropriate design and construction of HMA leads to smoother pavement and longer service life. HMA requires attention during its production at the plant and while hauling it to the project site to assure that a uniform material is produced and delivered to the paver. Additionally, paving (with pavers) and rolling (with compactors) are critical stages that determine the quality of asphalt pavement.
Many paving projects suffer from segregation during production and from low density after rolling. Unfortunately, when the mat is compacted, it is difficult to fix segregated and low density areas. It is therefore of critical importance to prevent material segregation and to achieve to the right density during rolling.
Description
This course focuses on the production and construction of HMA for paving projects, providing the fundamentals of HMA production, hauling and paving for defect-free results. Problems in stockpiles of aggregates and considerations in HMA production will be discussed, as will reasons for materials and for temperature segregation in the plant. Procedures and technologies regarding the delivery and rolling of HMA as well as best practices in the construction of longitudinal and transverse joints will be explained, but the main part of the course will deal with the compaction of HMA to achieve optimal field density.
Objective
The main objective of this course is to provide participants with a thorough understanding of important factors in the production and construction of HMA. The focus is to provide practical knowledge to those who are involved in paving projects to deliver a defect-free mat.
Target Audience
The course has been designed for contractors, consulting engineers, and highway agencies. Basic background knowledge of HMA is required. The main targeted audiences are paving crews, technicians, and engineers who supervise HMA construction projects.
Upon completion of the course, the participant will be able to:
- Recognize the main reasons for HMA segregation
- Apply methodologies of HMA production to minimize segregation
- Identify HMA hauling issues
- Understand how to deliver and pave HMA to minimize segregation
- Apply fundamentals of HMA compaction and different rollers
- Understand issues and problems in rolling HMA
- Construct longitudinal and horizontal joints to minimize roughness, and
- Apply the latest technologies to improve HMA paving projects

Instructor: Hamid R. Soleymani, Ph.D., P.Eng.
Hamid R. Soleymani has a B.Sc. and M.Sc. in Civil Engineering and Transportation Engineering from Iran University of Science and Technology and a Ph.D. from the University of Saskatchewan, Canada. After graduating, he worked as a postdoctoral research associate at the North Central Superpave Center at Purdue University (USA) for three years. Dr. Soleymani joined the Department of Civil & Environmental Engineering at the University of Alberta in 2000 and taught civil engineering materials, transportation, and pavement management systems at the graduate and undergraduate levels for several years.
He then worked with EBA Engineering Consultants as a senior pavements and materials engineer from 2006 to 2010. During this time, he completed many pavement preservation and materials projects and also conducted numerous research studies for Alberta Transportation and other highway agencies. Dr. Soleymani rejoined the University of Alberta’s Department of Civil & Environmental Engineering as the Director of Transportation Research Centre in 2010.
Dr. Soleymani has over 13 years of academic and industrial experience in the areas of pavement management, design and materials and is a registered professional engineer in Alberta. He has published more than 30 papers in technical journals and conferences. His expertise and research interest areas include: asphalt and Portland cement concrete; Superpave mix design; pavement design, maintenance and rehabilitation; materials characterization and modeling; pavement performance evaluation; mechanistic pavement design; and pavement management systems.
