Abstract

Roller compacted concrete (RCC), also known as roller concrete (or roll-crete), is a special type of concrete that has the same constituents as conventional concrete mixed with different proportions and a higher percentage of supplementary cementitious materials (SCMs). Due to texture, physical and mechanical characteristics, RCC is placed with a high-compaction asphalt type paver and compacted to a high density using vibratory rollers. The placement and compaction techniques of RCC results in a high strength rigid pavement with enhanced long-term performance. The aforementioned characteristics provide RCC with a material competitive advantage to be adopted in pavement projects. In this research, material cost of roadway segments designed and constructed using RCC is compared to different conventional pavement alternatives considering different project parameters including base and wearing surface material types, subgrade (soil) conditions, and highway level of traffic. The outcomes of this research showed that RCC pavement provides the departments of transportation with material cost savings regardless of the project parameters. Cost savings are maximized when RCC is used in highway construction with poor subgrade strength and under high traffic volumes. The incorporation of the research outcomes would provide DOT personnel with the required materials to improve roadway conditions within the United States.
