Course Catalogue.

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

• To design and recognize specification and construction activities that can reduce and recycle road building resources, reduce greenhouse gas emissions and promote environmental stewardship
• Communicate and promote sustainability concepts to road design and construction professionals and other stakeholders
• Provide and use logical and defendable tools to demonstrate and be accountable for environmental sustainability
• Better evaluate tradeoff and decisions with respect to sustainability practices
• Promote innovative design and construction practices that promote sustainability

• Understand and use systems to document the positive impact of sustainable practices

Description

Green pavements can be defined as roadways that use fewer long-term resources and/or create lower levels of “greenhouse” gasses, from all sources, over the life of the pavement.

These goals can be achieved through the following means:

• Utilize fewer resources than are currently used during construction or rehabilitation (or maintenance) of pavements
• Utilize pavement materials that create fewer greenhouse gasses during production, transportation and construction than are currently used
• Construct pavements that result in better fuel economy than are currently constructed (or reconstructed, etc.)

While many other approaches may warrant consideration, such as using mass transit, green vehicles or even bicycle riding, etc., this webinar concentrates on roadways in particular, recognizing that other aspects of green initiatives will take place in any event. There are several green rating systems that have been developed to evaluate the environmental friendliness of transportation design and rehabilitation projects. This webinar introduces the concepts of green rating systems and provides worked examples of three of the more commonly used systems for roadway projects. 

Course Outline

This webinar provides examples of the benefits of green infrastructure including:

• Better pavement design, proper use of pavement management techniques (“good roads cost less”), and timely pavement preservation
• Smoothness specifications for any pavement project
• Use recycled materials, such as rubber, recycled asphalt and concrete, waste and by-product materials, etc. 
• Use of supplementary cementitious materials in cement production and concrete mixture design
• Use recycled coarse aggregates for both concrete and asphalt mix designs
• Use material sources closer to the construction site
• Use polymer- and rubber-modified asphalt concrete, which oftentimes result in reduced thickness designs and longer-life pavements
• Use “smarter” pavement designs that break down projects by-lane and section-by-section wherever feasible

Who Should Attend

• Architects, engineers and technicians involved in sustainable road design and construction
• Agency personnel involved in the delivery of transportation infrastructure
• Consultants involved in the evaluation of pavement condition
• Recyclers and suppliers of alternative materials used for pavement construction
