Highway Engineering: Part 1 - Highway Materials, Maintenance and Rehabilitation

Duration: 8hrs

Good highways are so interwoven with every phase of our daily activities that it is almost impossible to imagine what life would be like without them. Each year, enormous quantities of construction materials are used for improvements to the public roadway system. Such projects require millions of tons of aggregates, bituminous materials, and cement, as well as vast quantities of steel, lumber, explosives, and petroleum products. 

This 8-hour interactive online course is the first half of the eighth course in a series on highway engineering. This course describes some of the physical characteristics and quality control tests for soils, aggregates, bituminous materials, and portland cement.

 At the conclusion of this course, you will:

• Be familiar with the basics of soils, including the general properties, dealing with moisture content, and understanding how and when the different types of soils are used.
• Learn how aggregates are manufactured and their uses.
• Understand material weathering, including the effects of frost, rain, chemical stability and other factors.
• Use formulas to better understand traffic loading as it relates to flexible pavement design.
• Identify equipment used in earthwork operations.
• Have knowledge of the essential of safe, practical and efficient excavation.
• Learn how to create and maintain embankments in roadway engineering projects.
• Understand the mechanics and the importance of finishing operations.
• Be familiar with the properties and uses of highway engineering bases and surfaces.
