Course Description:
 

Michigan's transportation infrastructure operates within one of the most demanding pavement environments in North America. Pavements throughout the state are subjected to repeated freeze-thaw cycles, frost penetration, seasonal moisture fluctuations, spring thaw weakening, thermal stresses, deicing chemical exposure, heavy truck traffic, aging infrastructure systems, and increasingly complex asset management challenges. These environmental and operational conditions create unique engineering demands that require a comprehensive understanding of pavement behavior, material performance, geotechnical conditions, drainage engineering, rehabilitation strategies, and long-term infrastructure management principles.

This course provides Michigan Professional Engineers with an in-depth examination of cold climate pavement design, evaluation, rehabilitation, preservation, and asset management practices applicable to both flexible and rigid pavement systems. The course begins by establishing the environmental and engineering foundations that govern pavement performance throughout Michigan, including freeze-thaw mechanisms, frost heave development, seasonal load variability, thermal stresses, and the interaction between climate conditions and pavement deterioration processes.

Participants will explore the identification of pavement distress mechanisms and root cause analysis methodologies used to diagnose deterioration within asphalt and concrete pavement systems. The course examines geotechnical engineering principles, frost-susceptible soils, subgrade performance, groundwater influences, moisture migration, and drainage engineering practices that significantly influence long-term pavement durability. Detailed instruction is provided regarding the design of flexible and rigid pavements for Michigan conditions, including structural design concepts, traffic loading considerations, material selection, thermal performance requirements, and environmental resilience strategies.

The course also provides extensive coverage of pavement materials engineering and durability, including asphalt binder selection, aggregate performance, concrete durability, freeze-thaw resistance, moisture susceptibility, and emerging materials technologies. Participants will learn modern pavement evaluation and structural assessment methodologies, including pavement condition surveys, Pavement Condition Index applications, Falling Weight Deflectometer testing, ground penetrating radar investigations, pavement coring, material analysis, and remaining service life evaluation techniques used to support rehabilitation and asset management decisions.

Comprehensive instruction is provided regarding flexible pavement rehabilitation engineering and rigid pavement rehabilitation engineering, with emphasis on selecting appropriate rehabilitation strategies based on pavement condition, structural capacity, drainage performance, material durability, and lifecycle performance objectives. Rehabilitation techniques examined throughout the course include overlays, recycling technologies, full-depth reclamation, concrete repairs, load transfer restoration, diamond grinding, slab stabilization, rubblization, and reconstruction decision-making methodologies.

The course further explores pavement preservation practices, transportation asset management frameworks, lifecycle cost analysis, risk-based infrastructure decision making, and the economic principles that support sustainable transportation system stewardship. Participants will examine how preservation treatments, performance forecasting, funding allocation strategies, and risk management methodologies can improve network-level performance while optimizing infrastructure investment outcomes.

Construction quality, quality assurance, quality control, performance specifications, and risk management principles are also examined in detail, recognizing the critical role that construction quality plays in long-term pavement performance. The course concludes with an examination of emerging technologies that are transforming pavement engineering, including smart pavement systems, embedded sensing technologies, digital twins, artificial intelligence applications, advanced performance modeling, resilient infrastructure strategies, sustainability initiatives, and future developments shaping transportation infrastructure management.

Throughout the course, Professional Judgment Alerts are incorporated to emphasize areas where engineering decisions require careful evaluation, risk assessment, and the application of professional judgment beyond minimum technical requirements. These alerts highlight common failure mechanisms, decision-making pitfalls, rehabilitation risks, asset management considerations, and performance issues that engineers frequently encounter when working with cold climate pavement systems.

To reinforce the technical concepts presented throughout the modules, the course includes four comprehensive case studies based on realistic cold climate pavement engineering challenges. Participants will examine frost heave and spring thaw failures along a Michigan rural highway, thermal cracking and premature asphalt pavement deterioration, D-cracking and structural rehabilitation of a concrete pavement corridor, and the optimization of an urban arterial pavement preservation program through asset management and lifecycle cost analysis. Each case study includes detailed engineering evaluations, decision-making analyses, rehabilitation planning discussions, and learning activities designed to strengthen practical application of course concepts.

Upon completion of this course, participants will possess a comprehensive understanding of the engineering principles, evaluation techniques, rehabilitation strategies, preservation methodologies, asset management practices, and emerging technologies necessary to design, evaluate, rehabilitate, preserve, and manage pavement infrastructure within Michigan's challenging cold climate environment. The course is intended for civil engineers, transportation engineers, pavement engineers, municipal engineers, county road commission personnel, consulting engineers, public works professionals, and infrastructure asset managers responsible for roadway systems throughout Michigan.
