Finite Element Analysis of High-Strength Concrete Pavement Made with the Addition of Fibres

Abstract

This paper provides an analytical Solutions and software-based analysis on the determination of Stress-Strain behaviour of High strength concrete pavement slab by applying number of axle load parameters given in the guideline of IRC-58 in the construction of Rigid pavement. The effect of the use of hybrid fibres, such as steel fibres and polypropylene fibres, on the behaviour of stress distribution is also studied. Shrinkage in HSC due to the incorporation of Hybrid fibres in different proportions at four Curing Temperatures is also analysed. FEA has been used to analyse the Shrinkage behaviour of High Strength Concrete Pavements with different geometry and thermal curing temperatures as (5°C, 20°C, 35°C, and 50°C). In the present research, the shrinkage analysis, Stress distribution behaviour in High Strength concrete pavement will be studied using Hybrid fibre of steel and polypropylene with a dosage of 1%, 1.5% and 0.1%, 0.2% respectively and by applying axle loadings of single, dual, tri and tandem axle as per IRC 58. Axle load is applied at the centre, edge and corner of the pavement slab and the stress distribution results are obtained. The Analytical solutions are obtained from Westergaard's equations and software-based results are compared with the analytical solutions and there are very less dissimilarities between both the results.
