초록/요약 도움말
The use of Roller-compacted concrete pavement (RCCP) in public and private applications has been increasing steadily in the past few decades. This pavement shares construction characteristics from asphalt pavement and material characteristic from conventional concrete pavement. Workability and compactibility play an important role in determining good mixture design for Roller-Compacted Concrete (RCC). Although strength is important for concrete, the construction would not be possible without appropriate consistency or workability. Typically, soil compaction approach is used for mixture design of RCCP. However, this method does not take workability in consideration. Another mixture design method was also introduced to RCC, consistency method, which mainly focus on workability. In this study, an improvement on mixture design method for RCC in pavement application is suggested by cooperating both laboratory parameters and field performances. By correlating laboratory parameters to real field performances, an optimal RCC mixture that can provide adequate performance can be achieved. For this study, various tests were conducted in the laboratory on RCC in order to define relationship between its main properties (consistency, strength and durability) and mixture proportioning. To correlate these properties to field condition, field test was also conducted on this concrete. A total of five sections of RCCP were constructed in Seokcho of South Korea for this test. Load carry capacity and surface properties of each section were investigated based on quality control parameter (consistency). The new understanding of these properties leads to the improvement of mixture design procedure for RCC in pavement application.
