The forest road pavements ensure the transportation of wood from the primary platform to the public road. The traffic has seen a rapid development in terms of transportation capacity. Thus, the forest road pavements are subjected to increasing traffic pressures. To respond, the researchers come up with the optimisation of the road pavement by using geogrids. The main purpose of this study is to present the behaviour of forest pavements reinforced with geogrids under the traffic load. The calculation of the stress–strain state was performed by using the finite element method. Therefore, within its first part, the paper presents the results similarity for the calculation of forest road pavements by using softwares such as Calderom 2000, ANSYS and Rubicon ToolBox. The second part approaches the consolidation of road pavements with geogrids to reduce the elastic vertical deformations of pavements. Findings of this study revealed that the 2D FEM method and ANSYS software offer similar results when compared to classical software. The geogrids located at various heights of the pavement produced different vertical elastic deformations and the increase of their modulus of elasticity did not seem to be cost-effective. However, when doubled, the average elastic deformation was found of about 2.49%.

林道的人行道确保了木材从主要平台到公共道路的运输。交通运输能力迅速发展。因此，林道人行道承受着越来越大的交通压力。作为回应，研究人员提出了使用土工格栅优化道路路面的方法。这项研究的主要目的是介绍在交通负荷下用土工格栅加固的森林路面的行为。应力-应变状态的计算是使用有限元方法进行的。因此，在第一部分中，本文介绍了使用Calderom 2000，ANSYS和Rubicon ToolBox等软件计算林道路面的结果相似性。第二部分采用土工格栅处理公路路面的固结，以减少路面的弹性垂直变形。这项研究的结果表明，与传统软件相比，二维有限元方法和ANSYS软件提供了相似的结果。位于人行道不同高度的土工格栅产生不同的垂直弹性变形，并且其弹性模量的增加似乎并不划算。然而，当增加一倍时，发现平均弹性变形为约2.49％。位于人行道不同高度的土工格栅产生不同的垂直弹性变形，并且其弹性模量的增加似乎并不划算。然而，当增加一倍时，发现平均弹性变形为约2.49％。位于人行道不同高度的土工格栅产生不同的垂直弹性变形，并且其弹性模量的增加似乎并不划算。然而，当增加一倍时，发现平均弹性变形为约2.49％。
