TRAINING.

Overview

Learning Outcomes

• 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

Purpose and Background
A large contributor to pavement deterioration is moisture infiltration.  Keeping the water out of the pavement has long been a mantra to pavement engineers.  Water on the pavement surface contributes to surface splashing and spraying and possible hydroplaning which can impact driver safety.  Water infiltration into the pavement structure and subgrade can also reduce the load bearing capacity of the pavement materials which in term reduces the service life of pavements.

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

Learn about the impact of water and infiltration and how this affects drive safety and pavement service life.

• Recognize pavement surface types and their ability to resist the impact of water on their performance
• Understand the differences in how permeability is measured for pavement materials and subgrades
• Recognize common methods to improve pavement surface friction
• Recognize techniques to reduce the impact of water on pavement performance

The primary discussion topics of this webinar include:

• Overview of pavement surface types
• Impact of water on pavement surface/base/subbase/subgrade
• Methods to measure pavement surface friction
• Methods to measure pavement permeability
• Methods to improve pavement surface friction
• Methods to reduce pavement permeability
• Quality assurance/control
• Key features to ensure pavement longevity

Who Should Attend

• Civil engineers responsible for the design, construction, maintenance and rehabilitation of pavements
• Agencies and other owners of highway, municipal and private sector pavement infrastructure
• Pavement material suppliers and contractors
• Operations personnel responsible for the maintenance and rehabilitation of pavements
• Private sector developers
