Evaluating the Impact of Using Bamboo Fibers in Pavement Design

Abstract

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.
