Evaluating the Impact of Using Bamboo Fibers in Pavement Design

The primary function of a pavement, which is characterized as a structure made up of layers, is to distribute the applied load to the subgrade. Typically, rigid pavements have three layers: the subgrade, the base layer, and the top layer. For the most critical and fundamental testing, the flexural test, beams are often casted to determine the hardened properties of pavement quality concrete. Cubes are casted to determine compressive strength. Concrete pavements have a longer lifespan, are more durable, and require less maintenance than flexible pavements, but crack in concrete pavement is one of the main problems observed in concrete technology due to drying shrinkage. One method used to reduce cracks is to incorporate fibers into concrete pavement. This report covers the subject of bamboo fiber-based rigid pavement settlement. The purpose of the study is to enhance the performance of bamboo reinforced concrete at the tension crack area. This report details the precise amount of fiber used, as an addition by weight of cement with a range of 0% to 1.5% However, this report helps us to know whether bamboo fiber can stop cracks from spreading and growing. Incorporating mineral admixtures,(metakoalin and flyash ) as a 15 % replacement for cement each reduces the permeability of concrete, increasing its durability, water tightness, and assistance in enhancing compressive strength, split tensile strength, and flexural strength. Compressive strength increases with the addition of bamboo fibre up to 1 percent; at 1.5 percent strength decreases; and as the percentage of fibre is raised up to1.5%, flexural strength also increases in this study.
