Case investigation on application of steel fibers in roller compacted concrete pavement in Thailand

摘要

This case study aims to investigate the improvement in mechanical behavior of roller Received 22 May 2019 compacted concrete pavement (RCCP) mixed with steel fibers. Hooked end type steel fibers Received in revised form 1 July 2019 were used at 0.5 and 1.0% by volume fractions. The modified Proctor test was adopted in the Accepted 19 July 2019 mix proportional process to determine the optimum moisture content for each type of RCCP. The Vebe consistency test was used to determine their consistencies under surcharge load. The experimental series consisted of compression and flexural performance tests to investigate the development of compressive strength, strain energy density, flexural strength, flexural toughness, and residual strength at different concrete ages. Tests were.
