Instructor Information: Jeffrey S. Melton,Ph.D., A.M.ASCE
This webinar was co-sponsored by ASCE's Geo-Institute and ASCE Continuing Education.
Course Length: 1 Hour
Purpose and Background
Sustainability has become an important element of civil engineering, yet there is confusion about how sustainability applies to different disciplines within civil engineering. Engineers involved with transportation and geotechnical construction (highways, airfields, embankments, levees, dams, etc.) need to know how the materials and methods they use affect the engineering life cycle and related sustainability of their projects. Recycled materials can be used to create longer lasting infrastructure that requires less energy to construct and maintain; and has a lower carbon footprint. Both public and private stakeholders, clients and owners are increasingly considering these green construction principles in the design and construction of their projects. Recycled aggregates such as RAP, RCA, RPM, RSG and BDC are used in pavement construction to enhance performance, save construction costs, and improve sustainability. In addition, blending recycled aggregates with cementitious stabilizers like coal fly ash, lime dust or cement kiln dust can further enhance sustainability, economics and long-term performance of the pavement.
This webinar reviews the benefits of using recycled material derived aggregates as a substitute for virgin aggregates in base course applications. Recycled base course aggregates can provide significant cost savings and enhanced performance of pavement structures, which can be further enhanced by using stabilization methods. This approach also promotes more sustainable pavement construction by reducing the need for virgin materials. This webinar will draw attention to applications in geotechnical construction for achieving sustainable outcomes.
Learning Outcomes
Participants will learn about the different types of recycled aggregates typically available in sufficient quantities for pavement construction, their characteristics, their design properties, and how to specify recycled aggregates in pavement applications.
Seminar Benefits
- Learn the latest developments in using recycled aggregates in construction
- Examine when and how recycled aggregates should be used in design
- Learn the latest information on how to improve long-term performance and reduce construction costs with recycled
- Gain a competitive advantage by having the latest design information for recycled aggregates
- Learn design methods for pavements with recycled aggregates with and without cementitious stabilization
- Learn how to specify recycled aggregates for construction
- Learn about how to assess potential environmental impacts associated with recycled aggregates used with and without fly ash stabilization
- Improve your practice by incorporating design information that enhances sustainability
Intended Audience
This webinar is primarily geared towards construction engineers, transportation engineers, materials engineers, geotechnical engineers and contractors who work in the highway environment. This webinar will also be useful for project managers, environmental engineers, recycled aggregate producers/suppliers, regulators and others who want to learn more about the use of recycled materials in infrastructure.
Seminar Outline
- Introduction to recycled pavement base aggregates: recycled asphalt pavement (RAP), recycled concrete aggregate (RCA), recycled road surface gravel (RSG), recycled pavement material (RPM) and building derived concrete (BDC)
- Types and attributes of RAP, RCA, RSG, RPM and BDC
- Design with recycled base aggregates (resilient modulus and plastic strain)
- Effect of impurities and freeze-thaw
- Fly ash stabilized recycled base aggregates: geotechnical properties and leaching characteristics
- Specifying recycled base aggregate
