English Abstract
The current development and advances in road constructions focuses on the incorporation of new materials such as geosynthetics layers to be used in the construction of flexible pavements.
To upgrade the performance under different types of stress levels.
The present research investigates the performance of typical standard flexible pavements when reinforced with different configuration of geogrid layers and reed mats.
A total number of 70 small scale model tests carried out at different relative density values for subbase and base layers (R.D= 65%, 77% and 88%).and incorporated with geogrid or reed mats.
The reinforced pavement sections were tested under both of monotonic & repeated loadings.
The monotonic model test results revealed that the maximum bearing improvement ratio for flexible pavement section reinforced by double geogrid layers equal to 81% as compared to selected flexible pavement section at R.D = 88%.
And 45% at R.D = 65% for subbase & base layers, while for second reinforcement technique by reed mats (interfacing reinforcement pattern),results revealed that the maximum bearing improvement ratio equal to 89%,30% as compared with unreinforced selected pavement section at relative density 88%,65% respectively.
The repeated model test results revealed , that a selected flexible pavement section reinforced by double geogrid layers (double reinforcement) at R.D = 88%, refers to best improvement carrying capacity accompanied by reduced generated settlement with increasing the number of stress cycles.
