Road pavement requires repetitive maintenance works to maintain satisfactory service level to the public. However, the repetitive maintenance works upon deteriorated pavement structure make negative effects to deterioration speed. It often leads to inefficient use of limited budget. For that reason, the pavements require reconstruction work to recover their original performance. Recently, construction demands in the Korean national highway have already been reached to maximum level, and the aged pavements start to demand much more reconstruction works. However, in the real world, road agencies have often been confused when they determine maintenance design for such aged road sections due to budget constraint. It is because there is no reliable long-term maintenance strategy that supports their decision making. To support their decision making, this paper aimed to suggest the best maintenance strategy considering changing process of pavement performance by repetitive maintenance works. As an analysis method, probability distribution and hazard function to estimate the life expectancy were adopted, and then the results were used for long-term life cycle cost analysis with deterministic or Monte-Carlo method under various scenarios. As an empirical study, the Korean national highway data that has long-maintenance history data since 1986 has been applied. Last, this paper considered quality assurance of maintenance work to improve maintenance quality. These could be important information as a part of long-term maintenance strategy of pavement.

This study aims to compare and analyze the quality of life of residents between those living in coastal and non-coastal areas. The indicators for the quality of life were divided into three different sectors. First, the economic sector observed the rate of population growth, the number of businesses per 1000 people, the employment and unemployment rate. The second was the environmental sector, which included the number of car registrations per capita, water supply and sewer service ratio, the urban park composition area per 1000 people and the road pavement rate. Thirdly, the social sector comprising data about the number of students per teacher, the number of sickbeds in medical institutions per 1000 people, the rate of traffic accidents per 1000 cars and the portion of social welfare budget in general accounting. The analysis method of standardized indicators and T-Test were carried out in 24 coastal cities and 51 non-coastal cities across the country. Results of the indicator comparison suggested there were significant differences in the number of businesses per 1000 people, the road pavement rate and the rate of traffic accidents per 1000 cars. From the results of each sector comparison, the coastal cities showed a higher value than non-coastal cities only in the economic sector. The quality of life comparison showed that coastal cities were better than non-coastal cities but were not statistically significant.
