- Recognize important pavement material requirements
- Recognize construction requirements to ensure success
- Understand the factors that may impact the performance of RCC pavements
Roller compacted concrete is a modified blend of concrete materials such as fly ash, Portland cement, water, sand, aggregates and additives that contains much less water than conventional Portland cement concrete. It has been in use for more than 50 years around the world and was initially used for dam construction as it was able to be placed quickly, had similar desirable properties to concrete and did not generate a high heat during hydration which can be a problem when placing mass concrete such as for dams. It began to be used in pavements, initially as a base or subbase but has been gaining more popularity in its use as a pavement surface. The RCC material is typically delivered by dump trucks and spread by specially modified asphalt concrete spreading equipment. RCC mixtures are compacted with the use of vibratory, tamper bar screeds, and typically but not always with static rollers to achieve a target density. RCC mixtures are relatively dry and depend on the stiffness as supplied to the job site to support the paver screed and rollers during placement and compaction operations. It does not require reinforcing or joint steel and is placed without forms.
This webinar outlines the basics of the RCC pavement and mix design, construction placement and finishing best practices and key features for the long-term sustainable performance of RCC pavements.
- Overview of RCC pavements and their differences from conventional pavements
- Key consideration in the selection of RCC for a project
- Overview of the key inputs of common RCC pavement design procedures
- Materials selection and RCC mix design
- Basics for construction to ensure performance
- Target quality control/assurance processes for success
- Recognize key design and construction features that impact performance
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
