This study examined the in-suit adaptability of geosynthetics as geocomposites, which can retard reflective cracks, to absorb stress from damaged roads. From the experimental results, for ultraviolet resistance, the retention of tensile properties was 80%. In addition, the geosynthetics of this study were found to be sufficiently stable for use as an asphalt overlay. The geocomposites as a hydraulic barrier showed 42~47% asphalt retention. The test of the crack growth rate and service life revealed the paved road to have twice the service life of a non-reinforced paved road.
