Design and Analysis of Flexible Pavement by Nonlinear Finite Element Method

Highway and pavement design plays an important role in the DPR projects. The satisfactory performance of the pavement will result in higher savings in terms of vehicle operating costs and travel time, which has a bearing on the overall economic feasibility of the project. A thorough analysis of the existing pavement is greatly required at this point of time, as an excessive amount of vehicle loads is passing through the project site and it is unknown whether or not the road pavement might sustain its structural integrity. The critical line of equal costs on the plane of CBR versus msa is also identified. This is a swing line which delineates the economic feasibility of two types of pavements. It has been found that the pressure vs settlement curve; pressure vs nodal stress curve ; pressure vs element stress curve are linear for small pressure range and then it become nonlinear. More nonlinearity is seen at higher pressure. Hence material nonlinearity must be considered while analysing and designing flexible pavements. This total work includes collection of data analysis various flexible and rigid pavement designs and their estimation procedure are very much useful to engineer who deals with highways.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
