Geosynthetics as a reinforcing material for earth structures have ever increased due to their excellent economy, fine external appearance, and easy construction. Geogrids are high-strength, orientated-polymer grid structures used to reinforce soil. This paper deals with the construction and sire monitoring for a 5.1m high-reinforcd slope with
steep. The purpose of site monitoring is to evaluate the applicability of reforced slope with geogrid. Full scale field performance during and after construction was monitored by incorporating instrumentation including strain gauges on the geogrid, and horizontal and vertical movements.

The one of the most important concerns in the design of the final cover system is to restrict percolation of water into the waste body. To minimize entering the water, the final cover system has the barrier layer that consists of a single compacted clay liner(CCL) or a composite liner with high density polyethylene(HDPE) overlying CCL. The HDPE as well as CCL can be damaged by landfill settlements. Therefore, this study was conducted to assess the effects of HDPE induced by settlements in the final cover system after closure. The results of the three test that is field test, lysimeter test in laboratory, and prediction of settlement represent that the HDPE in the final cover system is not pretty much affected by settlements and stable on settlements.

Long-term performance of smooth and textured type HDPE geomembranes which were used to the liner and slope systems of waste landfills was examined. Artificial surface defects were added to the surface of geomembranes by scratch addition apparatus specially designed. The mechanical and frictional properties, chemical and ultra violet light resistances and oxidative induction time(OIT) of geomembranes were examined for the cases of defective/non-defective surfaces. Frictional properties of textured type geomembranes showed more excellent than those of smooth type geomembranes. Finally, it was known that the long-term performance of non-defective and textured geomembranes was better than that of defective geomembranes through chemical and UV resistance and OIT tests etc.

Geotextile composites to improve the resistance to the application environment were manufactured of recycled polyester geotextile with carbon black as ultraviolet stabilizer and polypropylene geotextile by needle-punching method. Mechanical properties, ultraviolet resistance and chemical stability were evaluated. Retention ratio of tensile properties of polypropylene geotextiles were decreased about 50% with the exposed condition by ultraviolet but those of geotextile composites showed the slightly decrease. Geotextile composites which have larger weights of recycled polyester geotextile were more stable against ultraviolet. For chemical stability, the changes of tensile strength values of geotextile composites were in the range of -20~+10% at the various chemical conditions.

The major pavement distress types found in the domestic roadways include rutting, fatigue cracking, and reflection cracking which are results of the environment and repeated traffic loads. These distresses usually occur before pavements approach their design life, and therefore, a significant amount of national budget is spent for maintenance of roadway pavements. The purpose of this study is to establish a geosynthetics-asphalt pavement system. For the study, wheel tracking tests are conducted to analyze the controlling effect of geosynthetics on rutting of asphalt pavement. On the basis of these works, the reinforcement effect of geosynthetics on the rutting of the asphalt pavement is clarified and deformation characteristics of geosynthetics-asphalt mixture is examined.
Investigation on Effect of Rainfall on Performance of Soil-Reinforced Regtaining Wall

Journal of the Korean Geosynthetic Society, volume 2, issue 3, 2003, Pages 47~55
This paper presents the two field walls that demonstrate the effect of rainfall on the performance of soil-reinforced retaining wall. A field test wall constructed in Geotechnical Experimental Site at Sungkyunkwan University has been monitored for more than 8 months to study the long-term behavior of soil-reinforced retaining wall. The measured data showed a good correlation between rainfall and wall movement after wall completion. A case of failed soil-reinforced retaining wall also is presented to highlight the effect of rainfall on the performance of soil-reinforced retaining wall. Implications of the findings are discussed.
