Pavement Treatments to Improve Friction and Reduce Moisture Infiltration

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

• Understand the importance of pavement surface friction
• Recognize the impact of surface water and infiltration
• Know how to measure permeability effectively
• Recognize important pavement material requirements
• Understand methods to reduce permeability

Description
A significant contributor to pavement deterioration is moisture infiltration. Keeping the water out of the pavement has long been a mantra for pavement engineers. Water on the pavement surface contributes to surface splashing, spraying, and possible hydroplaning, which can impact driver safety. Water infiltration into the pavement structure and subgrade can also reduce the pavement materials' load-bearing capacity, reducing the service life of pavements. 

This webinar outlines the basics of the impact of moisture on pavements and the factors affecting permeability. It provides an overview of methods to measure moisture infiltration and pavement surface friction and details on techniques to reduce pavement permeability and improve pavement surface friction.
