Using of geosynthetic reinforcing interlayer in road construction

Lyudmila Shevchuk Nataliia Shlyun Yuliia Zaiets

The relevance of this work stems from the need to improve the durability and reliability of road surfaces, which are subject to intense loads, particularly from heavy vehicles, leading to the development of deformations and damage, such as cracks. This necessitates the use of reinforcement for road structure layers. The aim of this study was to determine the most effective placement of a reinforcing geosynthetic layer in the road structure to reduce the stress-strain state and increase its load-bearing capacity. Analytical methods were used for the calculations, as well as finite element numerical modelling to study the stress distribution in the layers for different reinforcing layer placement patterns. Numerical modelling revealed that geogrid reinforcement significantly reduces tensile stress in the road surface layers. The most effective placement of the geogrid is between the second and third layers of the road pavement, which, despite its primary purpose of preventing crack propagation, significantly reduces tensile stresses. The study showed that this arrangement reduces tensile stresses from 1,207 Pa to 1,011.6 Pa, representing a 20% decrease. At the same time, the use of the geogrid in the first layer increases shear stresses by 2.9%, and between the first and second layers, tensile stresses increase by almost 5%. However, overall, geosynthetics enhance the strength and durability of road pavements. Analysis of the resulting graphs confirmed that the optimal placement of the reinforcing layer corresponds precisely to the maximum tensile stress concentration, which improves structural strength, reduces deformation, and extends the service life of the pavement. The practical value of this work lies in the formulation of sound recommendations for the design of reinforced pavements, which will minimise material consumption and extend the service life of highways
