Cement content is generally low typically 70 to 130 kg m3.
It is therefore recommended that users determine how soon the pavement needs to be opened for traffic and then design the most cost effective pavement section and roller compacted concrete mixture meeting the requirement.
The purpose of this manual is to provide information and guidance on the use of roller compacted concrete rcc in dams and other civil works structures.
Roller compacted concrete mix proportioning method i of making roller compacted concrete.
Mix design proportioning methods for roller compacted concrete rcc.
To improve surface smoothness and texture rcc can be diamond ground or a thin asphalt or concrete overlay can be applied.
Uses the principles of soil compaction to produce a lean rcc where the optimum water content of the concrete is the one that produces the maximum dry density of the mixture.
Different mixes of roller compacted concrete can be designed to meet the different requirements of the two applications.
Roller compacted concrete rcc is an ultra tough zero slump concrete with compressive strengths greater than 4 000 psi.
Mix design proportioning methods for no slump concrete applicable for roller compacted concrete.
It is known for its rapid construction method.
Roller compacted concrete pavement is a type of non reinforced concrete pavement placed with high density paving equipment and then compacted with vibratory rollers.
While the finished product is essentially concrete pavement the engineering and construction of this pavement is very different from conventional concrete pavement.
