A review study on discrete fibers used for concrete pavement

Abstract

The development of road transport is absolutely necessary for the country's survival. The necessity for continuing maintenance and repair of conventional bituminous pavements points to the potential for cement concrete pavements. Traditional concrete roadways can provide a safe and effective flow of traffic.Due to its extended lifespan and minimal maintenance requirements, concrete has grown in popularity as a material for roadways. However, concrete roads have low ductility and tensile strength and are prone to spalling and cracking. The strength of concrete pavement is suggested to be increased in order to reduce these issues with concrete. Concrete shrinkage cracking is a significant issue with plain cement concrete pavement, particularly in tropical regions. The impact of adding polyester and polypropylene fibre to cement is briefly discussed in this research work. Checking the mechanical characteristics of the concrete mix design for M35 grade is the study's goal. Specimens such as cubes measuring 150 × 150 × 150mm, cylinders measuring 300 mm in height and 150 mm in diameter, and beams measuring 100 × 100 × 500mm are cast by adding various fibre dosages ranging from 0.5% to 4% by weight. The samples are stored for 7 or 28 days while they are being cured. Conducting destructive tests (Strength of compression, flexural strength, and tensile strength) and non-destructive tests on the specimen reveals its structural behaviour (ultrasonic pulse velocity test).
