Most of the time, road is bypassed by heavy vehicles such as trucks with heavy loads. So, engineer have to design precisely so that structure could meet both the strength and serviceability (deflection) requirements. The rigid pavement dynamic analysis in this thesis is modeled as a concrete plate with boundary conditions of all edges of the plate having semi rigid support and supported by Pasternak foundation model with elastic vertical spring support and continuous shear layer underneath. Transversal loads that cross the plate surface are dynamic load with initial speed and stable acceleration. The load is modeled as a single centered axis load equivalent to the variation of trucks such as Colt Diesel Double (CDD) Los Bak, Colt Diesel Double (CDD) Long Box, dan Colt Diesel Double (CDD) Bak. In this study will also be analyzed various types of parameters such as the value of vehicle coefficient, damping ratio value, and various supporting soil conditions are soft soil, medium soil, and hard soil. Solving the problem of dynamic plate with semi rigid conditions using Modified Bolotin Method (MBM) with two transendental equations. In solving these dynamic functions load we are using special characters of Dirac-delta function. The analysis is performed when the load is above the plate (0 ≤ t¬ ≤ t0), and the final result obtained is the response spectrum or critical speed of the vehicles and forces including moment and shear forces.Introduction KEYWORDS:MBM (Modified Bolotin Method), semi rigid, dynamic respons, transversal load, acceleration, Pastenak, Dirac-delta, rigid pavement. I. INTRODUCTION Plate structures that are often used on roads are rigid pavement structures (concrete layers) and flexible pavement structures (asphalt layers). Rigid pavement is considered to provide several advantages compared to roads using flexible pavement because it can be used on subgrade conditions which has a low or no uniform carrying capacity and rigid pavement is able to withstand heavy loads and spread the force that occurs efficiently towards the subgrade. In 1964, Kerr introduced the simplest elastic foundation model (the Winkler foundation model) [1]. The supporting soil layer is modeled as a supporting spring layer that is spread evenly along the plate. But this model only applies to uniform loads because there is no account of the connection between the layers of soil so as to produce uniform deformation along the plate [2]. One of the foundation modeling that produces a fairly good value and approaches the actual situation is proposed by Pasternak or known as Pasternak's foundation model. Pasternak modeled the supporting soil layer into 2 layers, namely the sliding layer and the spring layer under the plate. Several studies have been conducted based on this foundation modeling, including rigid hardness analysis placed on the supporting soil layer using Pasternak's foundation model and burdened with running loads [3]. Several methods can be used in resolving dynamic responses, such as finite difference methods, finite element methods, Rayleigh-Ritz methods, and Modified Bolotin Method (MBM). Alisjahbana and Wangsadinata conducted a study of orthotropic rectangular plates on Pasternak's foundation and loaded with dynamic transverse loads that move at a
