Analysis of Plain Concrete Pavement Deflection due to Swelling on Expansive Soil

Imam Fahmi, Ary Setyawan, Bambang Setiawan, - Wibowo


This research was conducted on the Surakarta-Gemolong-Geyer road, which is suspected to be built on expansive land. Every day, this road is always passed by large vehicles, so it is feared that it will be easily damaged if it is not routinely carried out maintenance. This study aims to analyze the damage to the rigid pavement on the highway using ATENA 3D software. The damage analyzed in this study is the deflection. The factors that make the crack large and wide were added to the heavy vehicle load and swelling. The swelling test on the soil carried out in the laboratory was 37 kPa. The results obtained after analysis with 3D ATENA showed differences in deflection at each loading variation. The variation of the middle loading with swelling pressure has a value of -15.49 mm; without swelling pressure, it is -16.37 mm. The middle loading variation with swelling and without pressure has a value of -15.33 mm and -12.4 mm, respectively. Corner loading variation with swelling and without pressure has a maximum deflection of 1.28 mm and -0.26 mm, respectively. This research can be used as a reference and prediction in identifying cracks that occur so that the government can carry out maintenance and rehabilitation before the road is damaged.
