In the beginning of September 2016, Thrace NG will participate at the 3rd International Conference on Transportation Geotechnics to present a comparison of internationally published methodologies for the efficient design of unpaved roads reinforced with geotextiles in the YTGE Session. This original piece of work was completed in Thrace NG’s R&D Labs, in collaboration with the Democritus University of Thrace, as part of a vision to create an original software for the calculation of road construction geotextiles.
Through a comparative analysis of all established methodologies, the paper highlights both similarities and differences, focusing on parameters such as soil subgrade, undrained shear strength (or CBR), number of vehicle passes, rut depth, the geotextile Elastic Modulus and its design strain. Turning theory into practice, the original work concludes with a user-friendly software tool (in spreadsheets) for the efficient design of unpaved roads reinforced with geotextiles. Reference is made to the criteria which are applied for the appropriateness of a geotextile simultaneously as reinforcement and separator of the unpaved road.
The original paper “Optimum Design Of Unpaved Roads Reinforced With Geotextiles: Comparison Of Internationally Published Methodologies” was written by Karavasili I. Styliani, Tastani Sousana and Markou Ioannis, and will be presented by Mrs Karavasili at the 1st Young Transportations Geotechnics Engineers (YTGE) Session of the 3rd ICTG 2016 in the City of Guimarães, Portugal (September 4-7, 2016). It was initially presented at the 11th HSTAM International Congress on Mechanics (27 - 30 May 2016, Athens, Greece).
