This study investigated the effect of geogrid reinforcement on the drying shrinkage behavior of high-strength concrete (HSC) pavements. Three groups of HSC prism specimens with dimensions of 75×75×280 mm were tested. The first was the reference group and included four unreinforced HSC specimens. The second and third groups included testing eight HSC specimens (four specimens per group) reinforced with a single and double geogrid layer, respectively. The triaxial geogrid was used as a drying shrinkage-reducing material. The geogrid layers were placed at 37.5 mm from the surface of the specimen. The HSC specimens were cured at a temperature of 28°C±5°C and a relative humidity of 50%±10% for 98 days. The strains and rate of the drying shrinkage were calculated. Test results indicate that the geogrid can reduce the drying shrinkage strains of HSC. The rate of formation of the drying shrinkage strains of the HSC specimens reinforced with the geogrid was lower than the reference specimens by about 54%/day.
