Experiences with Roller Compacted Concrete in Kansas By Lisa Harris W hen paving a road or street, two common choices for the material are asphalt and poured concrete. Each material has its pros and cons in terms of cost, maintenance, and longevity. Now, in some parts of Kansas, there is a third option: roller compacted concrete (RCC).
Roller-Compacted Concrete Pavements as Exposed Wearing Surface Version 1.2 – September 4, 2014 This document provides a guideline specification useful for developing project specifications for roller compacted concrete (RCC) as an exposed RCC pavement surface, that may or may not be diamond ground for smoothness and/or texture.
Introduction. Construction of Roller Compacted Concrete or Rolling Compacted Concrete (RCC) road pavements is well-spread in many countries all over the world. (Its name comes from the heavy steel drum rollers, which compact the concrete into final form). Problem statement. It has several advantages but its technique is different from that of „traditional" …
Abstract. In this study, field test investigation is conducted on roller-compacted concrete pavement (RCCP). A total of five sections of RCCP were constructed in Seokcho of South Korea for this test. Vebe time, a represented parameter of consistency, is employed as quality control parameter for RCC mixture.
Roller compacted concrete is a comparatively new engineering construction material which has potential cost/benefit advantages not identifiable with conventionally placed portland cement concrete. It is the intent of this study to review …

Definition: "Roller Compacted Concrete is a no-slump concrete placed by an asphalt paver and compacted by rollers" Materials are same as concrete – well graded, angular aggregates, cement, and water – but different mixture proportions. (Cement content around 300kg/m3) Zero slump (consistency of damp aggregate)
Experiences with Roller Compacted Concrete in Kansas By Lisa Harris Continued on page 2 Continued on page 4 RCC at 85 percent density, but a high-density paver produces a better result at 95-98 percent density. The machine's rollers further compact the pavement to about 98 percent. Water content in the

X-ray tomography images of Man100:MCC0 tablets which were compacted using a tableting load of 5, 10 and 20 kN using granules roller compacted using a pressure of 20, 50, 80 and 100 bar. Fig. 4 shows the X-ray images of granular material of varying ratios of mannitol and MCC compacted using a low RC stress before tableting.
Designers of roller-compacted concrete (RCC) dams are invariably concerned with control of thermal-induced tensile stresses and thus the possibility of uncontrolled cracking which can lead to leakage related problems in the dam. ... experiences from three other large RCC dams. The case studies presented focus on dams that have experienced some ...
