Finite element investigation of the prestressed jointed concrete pavements

Smoothness variations in early-age jointed plain concrete pavements

This paper discusses the variations in the early-age pavement smoothness at different measurement times and locations in three jointed plain concrete pavements ( JPCPs) representing different ranges of construction times. Surface profile measurements were made during the early morning and late afternoon hours at different locations of the instrumented JPCPs during the first 7 d after constructi...

Best Practices for Jointed Concrete Pavements / Blended Aggregates for Concrete Mixture Optimization Tech Brief

INTRODUCTION Historically, aggregate gradation has been controlled by specifications that call out envelopes for individual fractions, typically the coarse aggregate and the fine aggregate. The shortcoming of this approach is that the gradation of the overall system is not addressed. While it is sensible to stockpile coarse and fine fractions separately to prevent segregation, it is the combine...

Non Linear Finite Element Analysis of Reinforced and Unreinforeced Pavements

In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...

Finite Element Modelling of Steel-concrete Composite Beams Strengthened with Prestressed Cfrp Plate

This paper presents results from Finite Element Modelling (FEM) of steel-concrete composite beams strengthened with prestressed Carbon Fibre Reinforced Polymer (CFRP) plate. For the purpose of this study, three beams were strengthened using prestressed CFRP plate with three different levels of induced prestressing force. The models were developed using ANSYS FE package. The results of an experi...
