Abstract

Cakar Ayam Modification System (CAM) has been widely used as one of the solutions to road pavement problems in soft subgrade, although construction costs were initially high, the total costs incurred were smaller due to small maintenance costs. This research analyzes the deflection produced in a triangle patterned CAM system and quadrilateral with variations in the distance between claws of 2.25 m. Loading uses truck loads based on SNI 1725 2016 with three different position variations each in the middle and edge of the pavement. The analysis was carried out using Finite Element Method-based software which has been proven to be able to approach the original conditions in the field. The results of the analysis show that the CAM pattern with triangular pattern is better at reducing deflection that occurs compared to quadrilateral CAM systems. The deflection difference produced by the triangular CAM system against the clawless pavement system reached 36.97% while on the quadrilateral CAM system the difference was only 28.56%.

Abstract

Soft soil has low bearing capacity and high compressibility that can cause instability and long-term degradation that can make around some road settlement or wavy. A solution to prevent this soft soil problem was built Modified Chicken Foot, The function of Chicken Foot Foundation is to increase its bearing capacity. This research is using single load with variation distance of triangle foot foundation pattern whereas analysis of deflection using finite element method based. The research shows displacement result is depend on distance between load position and foot foundation, the closer distance between foot foundation the less it would result. The displacement result that happened at roadside is larger than at middle of the road, the difference between them is -6,8% up to 67% and The displacement result that happened in plate without pipe is larger than a plate with pipe, the difference between them is 12,31% up to 59,41%.
