TRAINING.

Overview

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

• Understand the key factors to determine the use of RCC for pavements
• Understand the importance of key design features
• Recognize important pavement material requirements
• Recognize construction requirements to ensure success
• Understand the factors that may impact the performance of RCC pavements

Description
Roller-compacted concrete is a modified blend of materials such as fly ash, Portland cement, water, sand, aggregates and additives containing 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 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, finishing best practices, and key features for the long-term sustainable performance of RCC pavements.

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
