Forensic studies are attempts to find solutions and to uncover the causes of the thing that has happened by relating them to certain standards stipulated by the relevant bodies. A forensic investigation is the process by which the forensic engineering team gathers the necessary information to determine the probable cause of failures that occurred. There is a methodology for investigative procedures that can be used when determining the cause of failure. This project focused to rural road embankment in rural area. The growth percentages of rural area will increase every year which mean this area will continue to increase in population thus affecting the role of the rural road system. The project has to be done in Batu Pahat soft clay located at RECESS site in UTHM campus. RECESS is an acronym of Research Center for Soft Soil; it was established in order to carryout field trials and adopts this as a national center for soft soil research in Malaysia. At the site, a full scale rural road embankment model was constructed with two (2) types different reinforcement. They are Rawell Geosynthetic Clay Liner (RGCL) and Woven Geotextiles(WG). The samples were taken for the types of different reinforcement and control section. The samples were core for further lab testing includes soil and aggregate test, asphalt test and geotechnical testing. Field testing was done at RECESS site. The instrument were used for field testing was Dynamic Cone penetrometer (DCP), Electricity Resistivity test equipment and Ground Penetrating Radar (GPR), On site testing includes several measurement like surface deflection, strength of layers and thickness survey. The end of this project, the author was define that data analysis can determine what the distress cause is by and provide the best selection of treatment that can stop the failures.
