บทคัดย่อ

This paper presents the current research and case studies regarding the use of geosynthetic-reinforced flexible pavement in Thailand. Physical model tests have been conducted to investigate the efficiency of using geosynthetics for flexible pavement, and the results indicate that geosynthetics can significantly decrease the permanent deformation of flexible pavement for new pavement and overlay subjected to cyclic loading. The permanent deformation of flexible pavement reinforced with geotextiles was significantly lower than that of flexible pavement reinforced with a geogrid. The permanent deformations of overlays reinforced with geogrids and geotextiles were approximately identical. Moreover, the shear strain base layer of reinforced flexible pavement was lower than that of pavement without reinforcement. The fabric effective factors are presented for different types of reinforcement utilised in flexible pavement design. For practical cases in Thailand, 'paving fabric' geosynthetics have been successfully employed in highway projects for overlays on rigid pavements to reduce reflective cracking. This paper also presents the construction sequence and engineering properties of geosynthetics for reinforced flexible pavement.
