Abstract:
At present, objects of responsibility (consequences) construction various classes, including SS-3 occurs in areas with possible manifestations of dangerous engineering-geological processes. One of such processes types is flooding. Based on the world experience, the main possibilities of using geosynthetic materials in various fields of construction are considered. Requirements for such materials and the conditions for their use are set out in European norms. An analysis of the program that is used to calculate drainage systems to meet force requirements in Ukraine is performed. These materials have good prospects for building in Ukraine with appropriate justification, considering the normative documents in force in our country.

Abstract:
During winter the formation of ice lenses causes frost heave within frost-susceptible materials. The uneven spatial distribution of heave due to heterogeneity results in severe damage to the pavement. Fissures are created, favoring excess infiltration, especially during subsequent springtime thaw. The installation of drainage can be beneficial in reducing the amount of water present in road foundations. Some uncertainty, however, exists about the sources of water feeding the lenses and, therefore, the optimal location of the systems. To assess the efficiencies of deep lateral drainage systems, a full-scale test has been undertaken along an existing road constructed on a glacial till subgrade. Three 150-m-long vertical geocomposite systems were installed at depths ranging between 2 and 3 m. In situ monitoring included piezometers and frost indicators and measurements of flow rates and pavement heave. To obtain a point of comparison, the measurements started 1 year before drain installation. For the period of observation the freezing indexes ranged between 1432°C-day and 1558°C-day, and the maximum frost penetration was 2.5 m. The flow rates varied considerably with the seasons, ranging between 1 ml/sec/linear meter during winter and 10 ml/sec/m during the April thaw. Before drainage the heave values ranged between 50 and 150 mm. After installation they were reduced by a factor ranging between 10 and 50 percent.

Abstract:
Drainage materials are widely used, among other uses, in the construction of landfills. Regulations require a drainage layer in the base and a covering for the landfill. The implementation of a gravel drain requires a lot of material and financial outlays. New geocomposite materials are an alternative, and facilitate construction. The aim of the research was to compare the drainage properties of the Pozidrain 7S250D/NW8 geocomposite and gravel drainage. The model test was performed on a specially prepared test stand. The research was carried out for model #1, in which the gravel drainage was built. Model #2 had a drainage geocomposite built into it. The test results show the values of the volumetric flow rate for geodrains, with a maximum value of 40 dm3·min−1. For the gravel layer, values of up to 140 dm3·min−1 were recorded. Another parameter recorded during the damming of water by the embankment was the speed of water suction by the geosynthetic and gravel drainage; the values were 0.067 and 0.024 m3·s−1, respectively. The efficiency of water drainage through the geocomposite was sufficient. It is possible to use the slopes of the landfill for drainage, which will reduce material and financial outlays.

Abstract:
Harmful effects caused by the water flow through various constructions (dams, embankments, etc.) are successfully solved by installing the various filter layers. The basic functions of filter layers are fast water evacuation with preventing the internal erosion and removal of small soil particles. These filter layers are usually made of coarse-grained materials (sand, gravel, stone aggregates), but in addition to the natural materials, the artificial geosynthetic materials are increasingly used. This paper presents the basic filter rules that need to be followed in order to perform a successful design of various filtration and drainage systems.

Abstract:
As one of the most important aspects of urban development, waste management is gaining importance as a result of the dramatic increase in the total world population and consequently in the volume of generated waste during recent decades. Landfills have been most widely adapted as long-term containers for disposed waste worldwide, and the collection and effective removal of the leachate produced represents an important element in the efficient functioning of a landfill facility. For this purpose, leachate collection and removal systems are designed in landfills to remove and transport the generated leachate to leachate management facilities for treatment or another approved method of disposal. Geosynthetic drainage materials have been widely used in leachate collection systems for drainage purposes. To function efficiently in a leachate collection system, the in-plane flow capacity of a geosynthetic material should be investigated appropriately over its service lifetime. Inaccurate estimation of the long-term flow capacity of the geosynthetic drains will result in inefficient or inappropriate performance of the system. The traditional approach to determine the long-term flow capacity of geosynthetic drainage materials is to perform a short-term index transmissivity test and then apply the reduction factors to consider the effects of the factors that influence drainage capacity. Recent studies have shown that the real decrease in the flow capacity of geosynthetic drainage materials can be much higher than that considered when applying reduction factors to the results of an index transmissivity test, as some factor boundaries that could significantly affect the hydraulic behaviour are not appropriately considered in this approach. These factors include the magnitude of the compressive stress that the drainage material experiences during its lifetime in a landfill, which is mainly influenced by the landfill size; the physical and geometrical properties of geosynthetic drains; and the characteristics of the materials that are placed atop and underneath the drainage layer. These deficiencies can lead to misestimating the drainage capacity of leachate collection systems and cause serious safety complications in landfills. In this study, a new approach was developed to more easily and accurately determine the in-plane flow capacity of the geosynthetic drains used in waste containment facilities. In this innovative method, for the first time, the effect of both creep and intrusion are systematically considered, and the deficiencies of the traditional methods are resolved. This approach concentrates on the close relationship between thickness and in-plane flow capacity. For this purpose, new equipment was specifically designed and manufactured. In this study, the effect of the geometry and rib configuration of geosynthetic drains on the hydraulic behaviour was investigated by conducting transmissivity tests performed on different samples under the specified range of compressive stress and hydraulic gradients. In the next step, the theoretical relationships that quantify the effect of thickness reduction of drainage materials on the transmissivity reduction were derived based on the classical Kozeny–Carman equation for each type of drain, considering their geometrical characteristics. The equation was then modified to be used in various boundary conditions. Later, the accuracy of these modified equations was investigated by comparing the results of the two types of experiments, including transmissivity and intrusion tests. Finally, the effect of the non-rigid flow boundaries on the hydraulic capacity of the geosynthetic drains was quantified. For this purpose, a series of intrusion tests were performed and experimental equations were derived based on the results. The innovative approach proposed in this study can significantly contribute to enabling improved estimation of the long-term hydraulic behaviour of leachate collection and removal systems, which is an integral part of safely designing new waste disposal facilities and expanding the existing facilities.

Abstract:
Geosynthetics are used in underground works, namely geotextiles for drainage and geomembranes for waterproofing. Because some groundwaters are aggressive to the materials they contact, as is the case of the sulphurous waters used in medical spas, the question arose as to whether those materials might be degraded and, in the process, contaminate the natural groundwaters. The appearance of unusual chemical elements in the waters of the medical spa is enough to be considered contaminated and therefore leads to the closure of those establishments. Once the question was raised, an experimental plan was developed to acquire some knowledge about the situation. Thus, in this chapter, after an introduction on the importance of the subject, and a brief survey on the state of the art, the geosynthetic materials studied are presented in detail, as well as the chemical composition of virgin groundwater involved in the process. The methodology implemented is presented, and the results are shown and discussed. Finally, the main conclusions on the evolution of the physical and mechanical parameters of the geosynthetics over time (8 months of study) are presented, with special focus on the chemical changes in groundwater quality when geosynthetic materials are used in contact with them.

Abstract:
This report presents findings of a research effort aimed at reviewing and updating existing Illinois Department of Transportation (IDOT) specifications and manuals regarding the use of geosynthetic materials in pavements. The project consisted of three tasks: evaluate current IDOT practice related to the use of geosynthetics; review research and state of the practice on geosynthetics applications, available products, design methods, and specifications; and propose recommendations for geosynthetic solutions in pavements to modernize IDOT’s practices and manuals. The review of IDOT specifications revealed that geotextiles are the most used geosynthetic product in Illinois, followed by geogrids. Several of IDOT’s manuals have comprehensive guidelines to properly design and construct pavements with geosynthetics, but several knowledge gaps and potential areas for modernization and adoption of new specifications still exist. Based on the review of the available design methods and the most relevant geosynthetic properties and characterization methods linked to field performance, several updates to IDOT’s practice were proposed. Areas of improvement are listed as follows. First, establish proper mechanisms for using geogrids, geocells, and geotextiles in subgrade restraint and base stabilization applications. This includes using shear wave transducers, i.e., bender elements, to quantify local stiffness enhancements and adopting the Giroud and Han design method for subgrade restraint applications. Second, update IDOT’s Subgrade Stability Manual to include property requirements for geogrids, geotextiles, and geocells suitable for subgrade restraint applications. Third, establish proper standards on stabilization, separation, and pumping resistance for geotextiles by incorporating recent research findings on geotextile clogging and permeability criteria. Fourth, promote the use of modern geosynthetic products, such as geotextiles with enhanced lateral drainage, and fifth, elaborate on proper methods for construction/quality control measures for pavements with geosynthetics.
