인터로킹 블록포장의 저속도로 적용성 평가

초록

PURPOSES: This study aims to evaluate the performance of interlocking block pavement system for low speed highway. METHODS: Through on-site monitoring, environmental impact assessment of interlocking block pavement such as heat island reduction,traffic safety, noise pollution were evaluated as compared with asphalt pavement. Also the pavement condition and roughness were evaluatedaccording to performance period. RESULTS: Surface temperature of interlocking block pavement was about 7 degree lower than asphalt pavement in midsummer. Comparedto asphalt pavement, vehicle speed reduction effect of interlocking block pavement was about 2kph. For low speed driving, the noise pollutionwas measured at a similar level for both asphalt and interlocking block pavement. After 42month service period, the breakage of block wasonly 0.24% for the whole surveyed area. IRI of interlock block pavement was estimated within the range of 5~8m/km. CONCLUSIONS : Depending on the performance monitoring results such as heat island reduction, providing traffic safety and keeping agood pavement condition for a long service period, it assures that interlocking block pavement was applicable for low speed road.
