# Introduction he natural rock asphalt is a sedimentary rock containing of high hydrocarbon substances. The natural rock asphalt with deposit of approximately 60,991,554.38 ton (24,352,833.07 barrel oil equivalent) occurs in the southern area of Buton Island, Indonesia (Asep Suryana et.all, 2003). Buton natural asphalt (BNA) blend is a type of modification asphalt which is made of 75% petroleum asphalt and 25% rock asphalt extraction. The rapid growth of national economic in recent years resulted in a lot of transportation infrastructure demand. Approximately 600,000 tons of petroleum bitumen must be imported annually to fulfill the maintenances and construction of new road demand. The utilization of Buton Natural Asphal for the road development increases the national asphalt industry growth. The water ponding on the road surface is caused by the heavy precipitation of high intensity rain fall. The water ponding problem during the rainy condition can be decreased by the employment of the permeable asphalt (porous asphalt) as a surfacing road pavement. Many islands in Indonesia possess lime stones resources that can be used as coarse aggregate. Quarsite Dolomite stone is a local name of lime stone (quartzite dolomite) that can be found in around of Banggailaut area, Indonesia. In order to produce permeable asphalt, Firdaus et.al (2014) employed Quarsite Dolomite stone and Buton Natural Asphal as coarse aggregate and bituminous material, respectively. The results of porosity test, permeability test, stability test, flow test, indirect tensile test and material loss test (Cantabro test) showed the bonding strength between Buton Natural Asphal and Quarsite Dolomite stones can be established thus can enhanced the resistance of porous asphalt against raveling, rutting and shoving. The solid that is subjected to the short time load are fundamentally characterized by the parameters of stress-strain curve. The failure of asphalt concrete specimens, the behavior of asphalt concrete under load as degeneration of the material and the limit of elasticity can be described by the stress-strain relationship for asphalt concrete in compression (S. Starodusbsky et.all., 1994). The unconfined compressive test combined with the indirect strength test can be used to calculate the cohesion strength and the angle of internal strength of the porous asphalt (Wu Shao Peng.all., 2006). S. Stardubski et all, the peak strain changes on average from 19 mill strain (0.0019) to 22 (0.0022) or 23 mill strain (0,0023) in the compressive strength of dense asphalt concrete with interval of 1.6 Mpa-5.4 Mpa. As the strength of permeable asphalt increases from 1,2Mpa to 2,1Mpa, the range of its peak strain is average from 0.001 to 0.005, which is similar to the peak strain of dense asphalt concrete. The unconfined compressive test result of porous asphalt containing Quarsite Dolomite stone and Buton Natural Asphal showed that the mixtime with 4% has compressive strength value and void, respectively. This work is a part of various extensive investigation projects on the development liquid Asbuton as bituminous asphalt binder and the suitability of Quarsite Dolomite stone as coarse aggregate in the permeable asphalt production. This paper reported the test results those are carried out to study the compressive strength and the strength strain curve in compression of the permeable asphalt. As course agregate on the surface layer Road Pavement.Capasity drain porous Asphalt were connecting correlasion with spacing hight and small porousity in structure Asphalt. Stability and Durability and Hydrolic conductivity its must be hight test than 20% (Ruz. et. al, 1990 ).Asphalt porous is open graded course Aggregate. Porousity asphalt porous (10%-15%) the structure made drain for flow water (Nur Ali, et al. 2005). # Fig. 1 : Permeable Asphalt Pavement Aggregate was specimen mineral who was done for mixture road construktion in the asphalt pavement it's mush be 90%-95% for the total weight strukture or 77%-85% for all volume (Alkin,et. # Methodology a) Mix Design Permeable Asphalt Pavement Testing Mix design permeable asphalt pavement the used composition open graded system.

Briquette make in for ? 10 cm and depth + 6.5cm. For open gradation we use lost aggregate ¾", ½" and lost filter by comparative 50 : 50. Fine aggregate we use filter number 4, finally number 200, we used 10%. Buton Natural Asphal we use all variation asphalt category: 3%, 3.5%, 4%, 4.5% and 5%. Test Indirect Tensile Strength (ITS) has been controlled by ASTM D6931-07. # c) Permeability Test i. Limitation Of Darcy's Law In a porous media, the hydraulic conductivity K represents the specific discharge per unithydraulic gradient, which means that the coefficient depends on both matrix and fluidproperties (Bear, 1972). From a dimensional analysis, the hydraulic conductivity can bederived as (Nutting, 1930): ( ) 2 v g k K = Re v d q = b) Multi Layer Test The roads are very important for land transportation infrastructure especially for distribution of goods and services, and to support the economic growth. The safety, comfortable, robust and economic roads will make people easier in their movement. There are three types of pavement construction known today, such as flexible pavement, rigid pavement, and the combinations that known ascomposite pavement. Permeable asphalt pavement was produced with used Quarsite Dolomite stone as course aggregate. The Quarsite Dolomite stone were broken in the spacing ? 3/8" ½"-¾" with the Buton Natural Asphal penetration 60/70. Briket at the Bitumen be done as the standard variation asphalt 3%, 3,5%, 4%, and 5% for testing Where k is the intrinsic permeability, v the kinematic viscosity and g the gravity acceleration.The intrinsic permeability is only a function of the matrix composing the porous media and its characteristics such as grain size distribution, tortuosity and porosity. For porous media, the Reynolds number (Re) can be defined as (Charbeneau, 2000): By the information the writers have, to determine the loads effect to the pavement construction of multilayer can be simulated using computer software i.e. EverStressFE.A pavement construction is a construction of pavement put over the subgrade to serves the traffic loads. Based on the bonding materials,pavement construction can be divided to:a. Flexible Pavement, b. Rigid Pavement, c. Composite Pavement. Modulus of elasticity, often called as Young Modulus isa coMparison between stress axial strainin an elastic deformation, so that modulus of elasticity shows the trend to deformed and back to the original form when under loads (SNI 2826(SNI -2008)). This shownby equation: E = ? ? (4) while E = modulus of elasticity, ? = stress and ? = strain Poisson Ratio (?) is the values of coMparison between horizontal strain (lateral strain) and vertical strain (axial strain) caused by loads thatparallel to axisand axial strain (Yoder, E.Y. and M.W Witczak. 1975). This shown by equation: ? = ? h ? v(5) While:? = poisson ratio, ? h = lateral strain, ? v = axial strain EverStressFE 1.0 version 1.0 (available for download at www.civil.umaine.edu/EverStressFE 1.0) is a user-friendly three-dimensional (3D) finite-element based software package for the analysis of asphalt pavement systems subjected to various wheel/axle load combinations.EverStressFE 1.0 is useful for both flexible pavement researchers and designers who must perform complex mechanics-based analyses of flexible asphalt pavement systems.Some of the major features of EverStressFE 1.0 are summarized below, Intuitive and user-friendly graphical user interface., Ability to model systems with 1-4 layers.., Modeling of multiple-wheel systems, Batch analysis capabilities. , Visualization of results. # Research Methods Methods that using in the tests are laboratory experimentaland analysis using software EverStressFE 1.0. The steps are : ? # Result and Discussion # a) Analysis Indirect Tensile Strength # d) Analysis Unconfined Compressed Test There are two configurations of stress strain curve were seen in all mixtures irrespective of the Buton Natural Asphal content. The first configuration shows some porous asphalt specimens have the initial bottom concave part that represents the settling of the specimen, the linear zone, the nonlinear zone of the ascending branch and comprises the peak and stretch immediately adjoining it on other side. This pattern is similar to the pattern of the dense asphalt concrete. The second configuration shows some porous asphalt specimens have the linear zone, the nonlinear zone of the ascending branch and comprises the peak and stretch immediately adjoining it on other side without the initial bottom concave part. This pattern slightly differs to the pattern of the dense asphalt concrete. The nonlinear part of stress strain curve of porous asphalt reflects the degeneration of the latter rather than the flow of very thin bitumen micro layers in it.
