“…Under loading condition, the soil material will tend to move in the lateral direction in the case where there is no restraint. Since geogrid is stiff in tension, it is able to limit extensional lateral strains developed in the soil material resulting to improved shear strength and stiffness [11][12][13]. For geotextiles, the improvement in CBR can be attributed to tension membrane effect.…”

“…Based on type of the material, intended use and manufacturing method, the categories of geosynthetics are; geotextiles, geogrids, geomembranes, geonets, geosynthetic clay liners and geocomposites [8][9][10]. In pavement construction, geosynthetics may be used for the following functions; separation, filtration, lateral drainage and reinforcement [11][12][13]. A geosynthetic may be used to perform one or more functions simultaneously when installed.…”

Reinforcement of flexible pavements using geosynthetics is gaining widespread application. However, there is inadequate understanding of strength development for non-woven geotextile and geogrid as reinforcement in Black Cotton Soil (BCS) and granular material in relation to cement stabilization method. Therefore, this paper presents experimental study to investigate strength development for BCS and granular material reinforced with geogrid and non-woven geotextile using California Bearing Ratio approach. The categories of samples tested were; neat, reinforced and cement stabilized. All samples were tested after 4 days' soak. Placement of reinforcement material in BCS was done at 0.3H and 0.6H for single layer reinforcement while for double layer reinforcement, it was done at both 0.3H and 0.6H. In granular soil, single layer reinforcement condition only was considered at 0.2H, 0.4H and 0.6H. Cement stabilization for both BCS and granular soil was done by the following percentages of cement increment; 1%, 2%, 3% and 4%. From the study, the strength improvement considering single layer reinforcement by geogrid and non-woven geotextile in BCS was 37.5% and 45% respectively. In granular material, CBR strength increased by 21% and 14% due to geogrid and non-woven geotextile respectively. Percentage increase in CBR of reinforced BCS corresponded to that of over >1% cement stabilization. To further enhance decision making between these strength development alternatives, it is recommended to advance it to cost analysis.

“…In other words, the use of waste material as a reinforcement agent enables both to recycle a waste material, which is so trouble not only to store but also to destroy, and to improve rutting performance. Evangeline, Sayida & Girish (2019) conducted a field study on five different road sections to investigate the long-term performance of the rural roads reinforced with coir geotextile located at the interface of the subgrade or subbase and base course layer. They carried out dynamic cone penetration, Benkelman beam deflection, and field California bearing ratio tests on five coir geotextile-reinforced roads and compared their performance with the unreinforced case.…”

This paper focuses on serving twofold benefits for the environment by providing not only recycling of a waste material but also improving rutting performance of sand subgrade under cyclic traffic loads. In this context, a series of laboratory experiments have been conducted to benchmark the performance of commercially manufactured geotextile and palm tree pruning waste (PTPW) as soil improvement agents. Experimental results of the study were evaluated based on permanent (plastic), total, and elastic deformation, rut depth reduction (RDR), traffic benefit ratio (TBR), percentage of elastic deformation, and resilient modulus (MR). In the view of experimental results, geotextile and PTPW-reinforced sand subgrades demonstrated well performance in the sense of permanent and elastic deformations when compared to unreinforced case. It is also realized that the most satisfactory performance was obtained when geotextile or PTPW are located at a burial depth of both 50 mm and 100 mm. In that case, TBR values of geotextile and PTPW-reinforced subgrades were almost the same at 20 mm permanent deformation (i.e., 6.71 and 6.76, respectively). Furthermore, when the results were evaluated based on RDR, it is observed that geotextile and PTPW reinforcements reduced the rut depth at the rate of 49.31 % and 37.15 % at the end of 5000 load cycle, respectively.

Quantitative and qualitative changes in recent years in the road industry require new technological approaches to road construction. Today some of the most used materials in road construction are geosynthetics. Geosynthetics have become interesting engineering materials in a wide range of applications and geotechnical, environmental, hydraulic, environmental, and private developments. The paper presents the research on the load and operational condition of the test model of a road reinforced with different geosynthetic materials. Geogrid and geotextile were used in testing. High-strength geotextiles or geogrids can provide adequate embankment reinforcement when properly designed and selected. Both materials can be used equally well, provided with the requisite design properties. Under the influence of the load from transport, the filler used for the cells is compacted. Currently, there is a redistribution of load throughout the entire volume of the monolithic structure with the grid. The tests carried out showed that using geotextiles leads to a decrease in the settlement coefficient by 25% and the use of a geogrid -by 38%. In rural areas of Kazakhstan, where the road network is in poor condition due to weak soils, strengthening the roadway with traditional materials will require large sums of money. Reinforcing the soil of unpaved roads with geosynthetic materials will allow more rationally and at a lower cost to improve the performance of unpaved roads in rural areas of Kazakhstan.
