“…Natural pozzolan inclusion to RCC mixtures resulted in a decrease of Ve-Be time and workability property (Ghahari et al, 2017). Similarly with the addition of polypropylene fibre, workability decreases as reported in a study (Benouadah et al, 2017). This can be attributed to the high water absorption properties of natural pozzolans.…”

Roller compacted concrete is a type of zero slump product produced from the same materials with conventional concrete. There are various methods for the design of RCC namely; corps of engineers’ practice, high paste method, roller compacted dam method and maximum density method. Development of RCC has led a significant shift in the construction projects primarily in dams as the traditional practise of placing, compacting and consolidation is slow. By using RCC in earth and rock filled dams made the construction process quicker and consequently shortened the duration of construction. RCC used dam projects and be completed 1-2 years earlier than the other dams as mentioned in the article of Bagheri and Ghaemian (2004). Use of RCC has substantially increased in the last decades especially for pavement applications. It has a low construction cost and can be done quickly compared to asphalt. It is widely constructed in areas/ roads carrying heavy loads in low speed. On the other hand, in recent years' utilization of RCC in urban areas such as highways and streets has also increased. It has been proved that RCC has a competitive advantage over high performance asphalt pavements in terms of high compressive strength, durability, low maintenance cost, longer service life. Like conventional concrete, fibre addition is widely preferred in RCC as well. Fibre addition has contribution to mechanical properties of RCC and sustainability.

ABSTRACT:Roller compacted concrete (RCC) pavement is used mostly for heavy duty vehicle operations such as log sorting yards, intermodal yards for containers, parking areas for military vehicles and trucks and automobiles, and aircraft parking ramps. Therefore, it is subjected to long-term loading which can cause permanent deformation. Therefore in this study, the long-term creep and drying shrinkage of RCC pavement up to 1 year was studied. High volume fly ash (HVFA) RCC pavement was developed by replacing 50% cement with fly ash. A total of five RCC pavements were developed; one control mixture, two RCC pavement mixtures and two HVFA RCC pavement mixtures. The four mixtures were developed by replacing 10% fine aggregate with crumb rubber by volume and addition of 1% nano silica by weight of cementitious materials. The results showed that the creep and drying shrinkage of RCC pavement increases with time, and with the incorporation of crumb rubber and HVFA and decreases with the addition of nano-silica. The creep strain of RCC pavement mixtures can be predicted at any given time using their compressive strength and age of testing.

“…But unlike conventional concrete, it is a drier mix-stiff enough to be compacted by vibratory rollers. Therefore, the fundamental characteristic of RCCP is its dry appearance, which requires the application of compaction efforts to consolidate the mix [3]. Little information is available on the performance of rubberized RCCP, because the majority of researches are conducted on conventional rubberized concrete and as such very little have been reported on RCCP mixes [6,[9][10][11]16].…”

This study aims to analyze the possibility of valorizing rubber waste in roller-compacted concrete pavement (RCCP) mixes as aggregates. The rubber particles were added to the mix as partial replacement of the total volume of gravels at different rates (5, 10, 15, 20, 25, 30%). The experimental approach followed in this research consisted of studying the effects of the incorporated rubber on the mechanical properties of RCCP. The obtained results show that the incorporation of rubber changes the behavior of RCCP mixes. In presence of rubber, the RCCP became more ductile. The principal disadvantage of rubber incorporation was the decrease in the mechanical properties of RCC. To remedy this problem, the rubber particles were subjected to a treatment and silica fume was added to the mix. The obtained results showed that the performance of RCCP can be improved by modifying the surface roughness of rubber particles. Therefore, a large part of strength losses were corrected.
