This Study was investigated in main breakage types of 50 interlocking block pavements in apartment houses and evaluated on their performance. According to performance evaluation, maintenance control index of 9 aged interlocking block pavements ranged 7.9 to 8.9. These values meant that the condition of interlocking block pavements were still good. Therefore, it was concluded that the 10-year cycle of the block replacement recommended by Ministry of Construction & Transportation is necessary to reappraise. To objectively evaluate the performance of interlocking block pavements, this study presented the criteria of maintenance control by combining two maintenance control standards suggested by Ministry of Construction & Transportation and the Japan Interlocking Block Pavement Engineering Association. Also, this study suggested that the domestic standard is necessary to include durability standards and quality standards of joint filling materials and bedding sand layer for increasing expectation life and reducing maintenance costs of interlocking block pavements.

대구광역시 동구에 위치한 'A'아파트를 중심으로 진입로, 보도, 보차도, 휴게공간, 체육공간의 점토벽돌블록포장, 소형고압블록포장, 인조화강석블록포장에 대해서 발생 하자를 조사하였다. 먼저 하자분석을 위해 하자유형 및 종류를 정의하여 현장조사표를 개발하였으며, 이를 바탕으로 각 공간 및 블록종류에 따른 하자를 조사 분석하였다. 그 결과 진입로의 소형고압블록은 16.14개/$m^2$, 보도의 소형고압블록은 12.04개/$m^2$, 점토벽돌블록포장은 9.55개/$m^2$, 인조화강석블록은 3.66개/$m^2$로 나타났다. 보차도의 소형고압블록은 10.82개/$m^2$, 인조화강석블록은 2.59개/$m^2$, 휴게공간과 체육공간의 점토벽돌블록은 각각 13.64개/$m^2$, 6.02개/$m^2$개의 하자가 발생하였다. 다음으로 블록별 발생하자 종류를 살펴보면, 소형고압블록에서는 골재분리, 인조화강석블록에서는 얼룩이 가장 많았고, 점토벽돌블록은 보도에서는 침하가, 휴게공간과 체육공간에서는 얼룩의 발생량이 많았다. 마지막으로 하자발생부위별로 살펴보면 진입로, 보도, 보차도에서는 경계부의 하자가 많이 발생했으며, 휴게공간에서는 중앙부의 하자가 많이 나타났다. 반면 체육공간에서는 중앙부와 경계부의 차이가 거의 나지 않은 것으로 분석되었다.

Permeable block pavement systems are widely used to relieve the flood and enhance water circulation. However, domestic design method has not yet been established well. Although AASHTO 93 flexible pavement design method is applied as a structural design method outside the country, there is a lack of information on layer coefficient of the permeable pavement materials, which makes it difficult to apply the design to various materials. Therefore, in this study, a method of calculating the layer coefficient of permeable block pavement materials by plate load test was presented and the layer coefficient of a permeable block pavement in a testbed was evaluated. Overall, calculated layer coefficient of open graded aggregate and permeable block pavement surface layer were similar to those of the conventional values. The presented method may be used to evaluate layer coefficients of permeable block pavements for design.

Recently, block and permeable pavements have been placed in apartment complex. However. it is hard to decide the cycle of maintenance and repair due to lack of performance evaluation criteria for these pavements. This study carried out life cycle cost analysis(LCCA) to present resonable alternatives of the pavements by considering initial construction cost, maintenance and repair cost along with the cycle of repair. According to results of LCCA, the interlocking concrete block pavement is the best alternative when the repair cycle of 20years is assumed, while asphalt concrete pavement is the best alterative when the repair cycle of 10years is assumed. Therefore, the repair cycle is most important factor to select alternative. Also, it is necessary to develop resonable performance evaluation index to quantify the cycle of maintenance and repair in the future.

As the percentage of permeable ground is reduced due to the increased impermeable roads of major cities, a heat island phenomenon can be dominantly observed, resulting in increased temperature. In addition, rainfall that would have been naturally absorbed and retained by the permeable ground is overflowed due to large volumes of run-off water, resulting in more sewer failures and increased erosion. In terms of permeable pavement system, block paving has been used anywhere as well as provides many years of service. The permeable block paving is an effective alternative to the more traditional asphalt or plain concrete for minor roads; furthermore, it looks a lot better than other pavements. In this study, the functional drainage evaluation of block paving was carried out, considering the usage of experimental sludge and wheel tracking test, in order to simulate the field condition of roads.
