N2 - Indonesia’s acceleration of infrastructure development brings about issues regarding land availability, suboptimal soil conditions, and the need for faster constructions, which are resolved by using slab-on-pile bridges for bridge constructions. However, the lack of beam elements in slab-on-pile bridges makes the monitoring of slab joint deflections more significant. Static and dynamic load tests are necessary to make sure the joint performs as well as designed. The tests were conducted using weighted trucks to induce the static and forced vibration. The data is compared to numerical analysis results. The results show that the occurring deflections are significantly smaller than the numerical results. The natural frequencies of the structure (16.05–18.75 Hz) is higher than the numerical analysis natural frequency (11.84 Hz). The maximum tensile strains of the structure (241.329 and 19.058 microstrains) are lower than the numerical analysis tensile strain (329.9 microstrains). This is due to the numerical analysis not factoring the extra stiffness due to prestressing, causing the structure to perform better than designed. The deflections of adjacent slab elements are almost identical, suggesting that the joint performs well and allows the slabs to behave as one unity. The dynamic amplification factor is calculated to be 1.325–1.563.
