“…The subgrade sample has a CBR value of 45.50%, which is a correlation of the soil qc value of 36.4 kg/m2 (0.000367 MPa). The qc value of the soil, according to Look [14] is classified as hard soil as a layer of soil supporting structures and/or foundations. The results of the Atterberg limits test, the soil has a Plastic Limit PL value of 21.08% and Liquid Limit LL of 34.25%, so it is a soil with low plasticity.…”

The bridge approach road embankment has a very important role as a link between the road and the bridge. In the post-construction stage, there are many cases of bridge approach road embankments, especially those with high elevations, potentially experiencing differential settlement. To overcome this, an analysis and planning study was carried out in increasing stability and overcoming the differential decline that occurred in the bridge approach road structure, especially in the approach slab structure with the end of the bridge. So that a bridge approach road model was developed as a substitute for the mass of soil embankment by conducting experiments and making a prototype of the Precast Concrete-cell Box structure model, which was given the maximum repetition and gradual plan load. While the method used in this research is the prototype model method, by conducting loading and settlement experiments on the bridge approach, especially on the approach slab. Furthermore, analysis and simulation are carried out under the condition of reaction force and maximum loading. From the results of the analysis, in the loading test of 2,761.00 kg, 2,717.00 kg 2,974.00 kg on the prototype model, the value of the decrease in LVDT 1-2-3 was 0.00 mm, the loading test of 3,956.00 kg and 3,887.00 kg obtained the value of the decrease in LVDT 1 and LVDT 3 of 0.00 mm and LVDT 2 obtained a decrease value of -0.01 mm which indicates a bending / deflection occurs in the approach slab structure, but it is still safe and no structure is required..
