도시재생 사업이 한창이다. 도시재생 사업이 순환형의 지속가능 개발이 되기 위해서는 빗물순환 복원이 필수적이다. 즉, 도시재생 사업에서의 LID 설계 프로세스가 필요하다. 먼저 기존 LID 설계 과정을 조사, 분석하였다. 기존 LID 설계는 현장의 특성과 빗물 흐름에 대한 고려가 부족하여 적절한 LID 시설 선정에 많은 제한이 있었다. 기존 설계 과정의 한계를 해결하기 위해 GIS를 이용한 수계분석이 필요하고, 빗물 흐름을 고려하는 LID 시설 설치가 중요하다. 또한, 본 연구는 토지주택연구원을 대상으로 LID 시범단지 사업을 수행하는 과정에서 발생한 사항들을 정리, 분석함으로써 도시재생 사업에 적용할 수 있는 방안을 제시하였다. Recovery of rainwater cycle is vital to be sustainable development. This means that LID design process is necessary for the urban regeneration. First of all, this study investigated and analyzed the existing LID design process. The existing LID design processes have many limitations to be applied to proper LID facilities because it is not considered in site conditions and water flow of the site. To solve the limitations of the existing LID design process, this study present the improved LID design process to be considered in hydrographic analysis through GIS analysis and finding points to install proper LID facilities. Through these considerations, this study present the improved LID design process to be applied to urban regeneration.

The purpose of this study is to present the resonable guideline of asphalt concrete pavements in apartment complex. To achieve this purpose was performed review of domestic and foreign guidelines, investigation of main distresses of asphalt concrete pavement, and structural analysis for the investigated cross-sections of the pavements in apartment complex. According to results of structural analysis, this study presented the standard cross-section of the pavement with subbase of 20cm, asphalt base of 5cm, and surface of 5cm in apartment complex. In urban areas, traffic is generally opened after asphalt base course is placed because of civil complaint by dust. Surface course is placed after all of work are completed. Considering these conditions, this study also presented the standard cross-section of the pavement with subbase of 20cm, asphalt base of 7cm, and surface of 5cm for urban areas that expect civil complaints by dust. 본 연구는 합리적인 단지 내 도로포장의 표준단면을 제시하기 위해 국내외 단지 내 도로포장 설계기준, 주요 파손형태를 조사하고 다양한 포장설계 단면을 대상으로 구조해석을 수행하였다. 이때, 현장에서 사용된 보조기층재와 노상토의 시편을 채취하여 CBR 및 MR 시험을 실시하였으며, 측정한 물성치를 구조해석에 적용하였다. 다양한 현장조건을 고려한 구조해석 결과를 분석하여, 표준단면의 포장층 두께를 보조기층 20cm, 아스팔트기층 5cm, 그리고 표층 5cm로 제안하였다. 또한, 민원이 예상되는 도시지역에서는 일반적으로 아스팔트 기층을 포설한 후 공사차량을 개방하여 작업종료 후에 표층을 포설하게 되는데 이러한 여건을 고려하여 단지 내 아스팔트 콘크리트 포장 표준단면의 포장층의 두께를 보조기층 20cm, 아스팔트 기층 7cm, 그리고, 표층 5cm로 제시하였다.

The purpose of this study is to analyze the structural stability of pavement due to water infiltration at the road with infiltration trench as using the FEM(finite element analysis). Five cases for FEM is divided considering the amount of rainfall and rain duration time. The results of FEM show that the more rainfall in a short period time is faster the change of moisture content. Also, it is the proportional relationship between and changing area of moisture content of more than 40% due to rainfall. Case 3 and 4 are necessary to check the installation of infiltration trench because of moisture content of more than 40%, recovery time of initial moisture content, and changing area of more than 40%. Case 1,2, and 5 have no a significant effect on road pavement structure due to lower moisture content and shorter duration time of higher moisture content.

PURPOSES : In this study, noise reduction effect of a two-layer porous asphalt pavement was investigated through site measurement and computer simulation. METHODS: To examine noise reduction effect, a 3 km long quiet pavement was installed by removing previous normal pavement, which had a rather low porosity. The studied site was a high-rise apartment building surrounded by the quiet pavement and Seoul ring road with heavy traffic volume, indicating relatively high background noise. RESULTS: The measurement result before and after installing the quiet pavement showed a noise reduction effect of 4.3 dB(A) at a distance of 7.5 m from the road. After validating the accuracy of simulation using SoundPLAN, the reduction in SPL(sound pressure level) at the facades by the quiet pavement was predicted by considering five different road conditions generating traffic noise from each road or in the combination of the quiet pavement and Seoul ring road. In the case of no noise from Seoul ring road, noise reduction at the facades was 4.2 dB(A) on average for 702 housing units. With background noise from Seoul ring road, however, the average SPL decreased to 2.0 dB(A). Regarding subjective response of noise, the number of housing units with a noise reduction of over 3 dB(A) was 229 out of 706 units (approximately 32%). For 77 housing units, the noise reduction was between 1~3 dB(A), while it was less than 1 dB(A) for 400 housing units. CONCLUSIONS: The overall result indicates that the quiet pavement is useful to reduce noise evenly at low and high floors compared to noise barriers, especially in the urban situation where background noise is low.

PURPOSES : As road pavement design in an apartment complex varies from one site to another, it is practically difficult to calculate and estimate the traffic volume of construction vehicles. Therefore, this study introduces a methodology to estimate the number of construction vehicles and use it as an indicator to evaluate the conditions of road pavement in an apartment complex. METHODS: Through a literature review and site survey, the operational status of the construction vehicles passing through the site was identified, and the factors affecting the number of construction vehicles were analyzed. The methodologies used to estimate the number of construction vehicles were verified by calculating the Cumulative Load Prediction Index (CLPI), which is a predictive index of the cumulative load on each path. By using this index, the traffic volume of construction vehicles can be estimated based on the number of households in an apartment complex. To prove this definition, we examined the surface and core conditions, and compared the results against the predicted values. RESULTS : By comparing the Cumulative Load Prediction Index with the crack rate on the pavement surface, we obtained a correlation coefficient of 0.92. Furthermore, the analysis indicated that the core condition rate would decrease as the Cumulative Load Prediction Index increased. This correlation between the Cumulative Load Prediction Index, and the pavement surface and core status demonstrates that the traffic volume can be estimated by considering the number of households. CONCLUSIONS: The Cumulative Load Prediction Index presented in this study is a suitable indicator for estimating the conditions of the road pavement in an apartment complex by considering the number of households in the complex, even if the construction processes and characteristics vary.
