Experimental Verification of Properties of Roller-Compacted Concrete for Pavements

Abstract

Increased requirements on environmentally friendly construction process of road structures with emphasis on economical savings and durability of roadways lead to search for new material solutions for pavements. Roller-compacted concrete (RCC) is an ordinary concrete poured and compacted with machines typically used for placement of asphalt pavement layers. Its main advantage is relatively good ratio between mechanical properties and overall costs during construction, operation and maintenance phases. After extensive literature review on the use of RCC in the world, the authors focused themselves on a series of tests of specimens made from RCC mix to verify the main characteristics of the material. Slump, compressive and flexural strength, resistance of concrete to deicing chemicals and resistance to abrasion was tested. The results were assessed from the point of view of exploitation of RCC in pavement structures.
