초록

급속한 산업화가 진행되면서 건물과 인공 포장된 도로의 급격한 증가하고 있다. 이로 인한 도심 집중강우에 따른 도로침수, 포장체 파손 등이 발생하고 있다. 이에 대한 해결책으로 도심지 내 투수성 포장의 필요성이 대두되고 있다. 본 연구는 투수블록의 차도포장 적용 가능성 현장 평가를 하기 위하여 공용기간 동안 차도용 투수블록의 투수성능을 평가하였다. 평가결과 줄눈재 및 받침안전층은 품질관리기준을 만족하였으며 휨강도는 1개소만이 5.29 MPa로 기준을 만족하였다. 실내투수지속성시험의 결과는 4개 제품중 1등급 1개, 2등급 1개, 3등급 2개로 평가되었으며 현장투수 및 현장 침투능은 각 제품의 9개월 간의 추적 조사 결과 1개 제품을 제외한 모든 제품에서 0.1 mm/s 이상의 품질기준을 만족하였다.

The rapid expansion of buildings and paved roads increases the risk of flood disaster in an urban area. One of the solutions can be the use of permeable pavements. This study evaluated the permeability of permeable blocks used for the roadway pavement. Joint fillers and mat sands of the investigated blocks met the corresponding standards. The flexural strength of the blocks was 5.29 MPa to meet these standards. Based on interior permeability test results after pollution, the four products evaluated were categorized into the following three levels: One for the $1^{st}$ level, one for the $2^{nd}$ level and two for the $3^{rd}$ level. From the field permeability test and pervious concrete infiltration test results nine months after their construction, all the products except one passed the quality standards of 0.1 mm/s.
