Abstract

In an era of rapid technological and infrastructural development, the quality of roads is critical to ensuring efficient and safe mobility. Composite roads, which consist of a mixture of different types of construction materials, have become an attractive option in road development in various regions. However, to ensure the success of composite roads, structural consistency and performance must be considered. A Light Weight Deflectometer (LWD) is a device used to measure the instability of road layers by applying surface pressure and measuring the resulting deflection. Although the use of LWD is common in the road construction industry, specific research on LWD consistency testing of composite roads is limited. This study investigates and analyzes the consistency of LWD on composite roads to improve the understanding of its performance. The results of the study on composite pavements conducted at three points with 30 trials showed a coefficient of variance of less than 5%. This result indicates very strong data consistency. Based on these consistency values, the LWD is acceptable, but it needs to be correlated with other tools to determine its validity. If the consistency and correlation meet the requirements or are less than 5%, LWD has a good chance of being used in composite pavements.

Abstract

Institution of education has important role to take part in solving problems in Bandung city community development. Population growth inBandung drives the impact of facility andinfrastructure addition, including in primaryschool facilities. The land area of school could not be expandable and so its insufficient and facility infrastructure because of its location among slums settlement and traditional market.The Departement of Eduaction and Cultural hassustainable programs for improving school facility and infrastructure. The facility and infrastructure of Sekolah Dasar Negeri 027 recently has not been longer proper for physical and capacity for teaching and learning activities. In this program, abdimas team helps to carry out the planning renovation and supervision assistance process of Sekolah Dasar Negeri 027. This program involves architect and civil engineer to plan, design, count the structure of new classrooms addition and also supervise the renovation for few room of Sekolah Dasar Negeri 027. The output of this activity is to fulfill the need of the SDN 027 community to carry out the teaching and learning process.
