Abstract
Geogrid-reinforced asphalt pavement is a pavement type applicable to overlay for repair in addition to new construction. The geosynthetic materials are placed between the asphalt layers to stop or delay propagation of the cracking existing at lower layers and to reduce the rutting. In this study, the cracking, rutting, IRI, and deflection were investigated to compare the performance between geogrid-reinforced asphalt pavement and ordinary or polymer modified asphalt pavement. Based on field conditions, the 11 sections were classified into 3 groups; sections proper to compare, sections with restrictions to compare, sections with difficulties in comparing, and the data was statistically analyzed. Larger resistance to rutting and increased IRI were measured at the geogrid-reinforced asphalt pavement sections comparing to the ordinary or polymer modified asphalt pavement sections. However, the deflections of the pavements were similar and the resistance to the cracking could not be compared because of short pavement lives.
