Geosynthetics are human made material used to reinforce soils to improve the bearing capacity and permeability of the soil, reducing soil settlement. Geosynthetics application plays a vital role in the highways constructions with no additive layers, such as cement concrete, asphalt concrete, or in a subgrade layer that affects the bearing capacity of unbounded layers. This paper presents the geosynthetics as a tensional material that has been used for reinforcement of clayey soil. Laboratory California bearing ratio (CBR) test samples were prepared with clayey soils. Clayey soil containing unreinforced soil and reinforced soil. The sample comprised thermally bonded nonwoven geotextiles (NW) and superior needle-punched nonwoven geotextiles (SNW) with different characteristics (NW 8, 10, 21, 30 and SNW 14, 25, 62, 75) with three-layered, based on the sample materials to perform defined tests. These tests show that, bearing ratio of reinforced soils with thermally bonded nonwoven geotextiles increases.

土工合成材料是用于加固土壤以提高土壤的承载能力和渗透性，减少土壤沉降的人造材料。土工合成材料的应用在无添加剂层（例如水泥混凝土，沥青混凝土）或影响无边界层承载力的路基层中的高速公路建设中起着至关重要的作用。本文介绍了土工合成材料作为一种抗拉材料，已用于加固粘土。加利福尼亚实验室的承载比（CBR）测试样品是用黏性土壤制备的。粘土质土，包括未加固的土和加固的土。该样品包括三层热粘合的非织造土工布（NW）和具有不同特性（NW 8、10、21、30和SNW 14、25、62、75）的高级针刺非织造土工布（SNW），根据样品材料执行定义的测试。这些测试表明，具有热粘合非织造土工布的加筋土的承载比增加。
