KAJIAN KARAKTERISTIK MEKANIK ROLLER COMPACTED CONCRETE (RCC) SEBAGAI BAHAN PERKERASAN JALAN
ABSTRACT: RCC concrete
pavement is concrete pavement that has durability, economic value, long life
and low maintenance service life. In this study conducted in the field
compaction with baby roller more or less as much as 3-5 times the trajectory,
and retrieval of test specimen cubes (10x10x10) and beam (10x10x30), with a
concrete cutting tools. Taking a test specimen in the laboratory of conventional
concrete cubes (15x15x15). The composition of mixtures used were water: sand:
split: cement is 108:811:1217:300 (kg/m3). Variations in the age of treatment
(7,14,21 and 28 days), and performed two tests, namely: the testing of
compressive strength and lentur.Hasil tensile strength showed that the mixture
of the same compressive strength and flexural strength RCC is higher than
conventional concrete., more economical, faster utilization after the
implementation of the work. Compressive strength obtained at 28 days was 29.25
MPa and 5.14 MPa flexural tensile strength, is still included in the range
required by the ACI (American Concrete Institute) that the range of tensile
strength for RCC split between 400 (2.75 MPa) and 600 psi (4.13 MPa) at 28 days,
for compressive strength are eligible for RCC mixtures where, according to the
specifications for RCC of the PCA (Portland Cement Association) where the
requirements are between 28 MPa - 69 MPa.
