Implementasi Levelling Sensor Pada Slipform Paver Terhadap Produktivitas Dan Kualitas Rigid Pavement

Abstract

The development of construction technology has encouraged the implementation of sensor-based automated systems as an effort to improve the productivity, accuracy, and quality of rigid pavement construction. One of the technologies applied in such work is the Wirtgen Slipform Concrete Paver, which is equipped with a levelling sensor that automatically controls the elevation and pavement thickness during the concrete paving process. This study aims to analyze the implementation of the levelling sensor on the Wirtgen Slipform Concrete Paver and evaluate the machine's productivity in rigid pavement construction on a road improvement project in City X. The study employed a descriptive-analytical approach using primary and secondary data related to construction activities, machine specifications, sensor operating mechanisms, and field conditions. The analysis was conducted by examining the operating mechanism of the levelling sensor and calculating the productivity of the Slipform Concrete Paver based on the paving width and thickness, machine operating speed, and efficiency factor. The results show that the levelling sensor continuously detects the position of the stringline as an elevation reference. The sensor readings are then transmitted to the hydraulic control system to automatically adjust the mould position, thereby maintaining the concrete thickness in accordance with the design specification of 30.5 cm. Based on the calculation results, the machine productivity was determined to be 49.94 m³/h. The implementation of the levelling sensor technology improves dimensional accuracy, maintains the smoothness of the concrete surface, reduces the potential for rework, and enhances construction efficiency.
