Course Catalogue.

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

• Be able to recognize and use current common pavement design procedures.
• Understand common design and construction features important to the performance of both asphalt and concrete pavements.
• To design and recognize specification and construction activities that can improve the performance of pavements.
• Communicate and promote good road design and construction practices. 

Description
Our pavements are one of the most valuable and used physical assets in North America.  Roads, highways, airports and parking facilities serve to support the movement of goods and people for both business and recreational purposes.  These assets impact the daily life of almost everyone.  The peak of road building in North America was during the 1960s and 70s.  The focus was to provide safe, durable and accessible vehicular transportation for everyone.  Since then, our focus has been mostly on the maintenance and rehabilitation of this valuable infrastructure.  Unfortunately, demand has exceeded our capability to maintain our roadway infrastructure.

Semi-rigid pavements are an alternative to the traditional flexible and rigid pavements we commonly use in North America.  The most common semi-rigid pavements include natural stone, interlocking concrete and clay brick pavements.  The use of these types of pavement was common through the 1800s and 1900s in North America but fell out of favor with the sub-urbanization of our major cities.  Stone and brick pavements were overlaid with asphalt concrete in the downtown areas of older cities.

Semi-rigid pavements have many advantages over asphalt and concrete pavements.  They are very commonly used for ports and intermodal terminals as they offer the ability to accommodate vertical and horizontal shear movements without serious damage, can be removed and replaced to access underground utilities at minimal cost, provide a long-term sustainable pavement and offer overall life-cycle cost advantages.  Semi-rigid pavements are very durable and have very few maintenance needs if installed correctly.  European cities and towns use more than 10 times as much semi-rigid pavements compared to conventional pavements in their urban areas compared to agencies in North America.  Their appearance is also aesthetically pleasing compared to conventional pavements.

This webinar aims to develop an understanding of the key features of design, construction, maintenance, and rehabilitation to assist agencies and other owners in ensuring that they are getting what they paid for and cost-effectively extending the service life of our pavement infrastructure.
