Abstract

The function of road pavement is to carry the traffic load quite safely and comfortably, and before the age of the plan does not cause significant damage. To obtain stability from the pavement must know the factors that can damage the pavement itself. The pavement construction can be tried so that to overcome all destructive factors, caused by traffic forces one of them is the vehicle brake force in the form horizontal force that distributed to the surface of the road pavement. This research aims to analyze horizontal loads on the pavement Nailed-slab System then compared to rigid pavement from the type of pavement per segment and continuous. Modeling of road pavement consists of Nailed-slab System and rigid pavement was carried out with the help of finite element method PLAXIS V.8.2. software. Analysis of horizontal loads in the form of brake force on vehicles using per kinetic energy. Modeling of road pavement consists type of road pavement per segment with a length of each segment of 12m and width of 6m and the type of continuous road pavement with a plate length of 300 m and a width of 6 m. The length of the road pavement of the two types of modeling is 300 m and width of 6m. From the length of the road pavement there are 5 load points with a distance of each load of 75 m. The resulting displacement of the Nailed-slab will be compared to rigid pavement. Road pavement was analyzed in soft soil. Nailed-slab System pavement plate thickness of 0.15 m, pole diameter of 0.20 m with a length of 1.50 m, distance between poles 1.20 m, and rigid pavement plate thickness of 0.30 m. Horizontal load of truck and trailer types. Road pavement of the Nailed-slab System produces horizontal displacements greater than rigid pavement, proven when given a load of 64 kN from the type of segment on the Nailed-slab which is 0.128 mm greater than the conventional rigid pavement which is 0.078 mm, and vertical displacements of the Nailed-slab System which is -1.926 mm smaller than conventional rigid pavements which is -2,720 mm. The type of Nailed-slab and conventional rigid pavement are -0.127 mm and 0.078 mm produce in horizontal displacements greater than the type of continuous pavement which is 0.119 mm and 0.063 mm, and vertical displacements of the type of segment on the Nailed-slab which is -1,962 mm smaller than the type of continuous pavement of -2,518 mm, but the rigid type per segment pavement is -2,720 mm larger than the continuous type of -2,628 mm. loads at points A and E which are 0.078 mm and 0.079 mm produce horizontal displacements smaller than loads in the center of the plate, loads at points B, C, and D which are 0.173 mm, 0.179 mm and 0.125 mm, and vertical displacements are more uniform than all load points on Nailed-slab which are -1.962 mm and conventional rigid pavements are -2.720 mm.
