Abstract

Every year the government allocate substanstial amount of budget for road construction, betterment and maintenance all over Indonesia either in national roads or provincial/ regency/ city roads due to early road deterioration. Such early roads deterioration also exists in Banten Province. This research is intended to analyze whether the implementation of quality standard met the technical specification and to analyze the most dominant variable determining road work quality using principal analysis component. Data collection from the respondents was conducted by distributing questionnaires related to road works in Serang-Pandeglang link containing 22 statements expressing 5 variables, i.e. human resources, road materials, equipments, construction method and material testing. Results show that one of 22 statements was not statistically valid and was therefore removed. After descriptive analysis, it was generally found that only about 40-60% of the respondents always/ almost always conduct 21 statments in the questionnaire. This indicates that both contractor and supervision consultant were not consistently implementing quality standard and therefore did not meet the technical specification. Based on factor analysis using principal component analysis, three factors influencing implementation of quality standard of road work were extracted. In factor 1, the most influencing sub variable was calibrating all equipments, conducting mix design and ensuring readiness of equipments (loading factor 0.811). In factor 2, the most influencing sub variable was conducting at least two number of passes of final compaction (loading factor of 0.788). In factor 3, the most influencing sub variable was testing of mix design to find values of stability, void, asphalt content, flow and density (loading factor of 0.860).
