Michigan is a state with high precipitation and cold winter temperatures (wet-freeze climate). This wet-freeze climate makes the pavement system in Michigan different from many other regions. Compared to other regions with different climates, the most noticeable pavement distress in Michigan is freeze-thaw induced damage. Thermal cracking and fatigue cracking in asphalt pavements and transverse cracking and joint faulting in concrete pavement are also major forms of pavement distress. In addition, potential damage from de-icing materials and snow removal vehicles are concerns. These concerns have limited the usage of some pavement types that are widely used in other states or countries.
The success of this research project can enable MDOT to understand which best practices in other states or countries can be potentially implemented in Michigan.
The objectives of this research include:
- Document best practices nationally and internationally for pavement design, pavement materials selection, construction (workmanship), and maintenance of roadway pavements in wet freeze climates that are similar to MI,
- Identify barriers to implementing the best practices presently not used in MI,
- Recommend the best practices that could be implemented in MI
