AB  - The main objective of this study is to assist the practicing road engineers to design an overlay by using a simple software. To date, most of the PWD's engineers (especially road engineers) calculate the overlay thickness manually. The process of calculation is tedious and time consuming. By having a simple computer program, the calculation time will be shortened significantly. Basically, in this program, the PWD's overlay design method has been used to obtain the overlay thickness. In this method, the existing road condition is evaluated by using some common in-situ methods like FWD, DCP and pavement coring. The traffic estimation is based on Arahan Teknik (Jalan) 5/85 Manual on Pavement Design. By having the information of the existing road and traffic condition, the required overlay thickness can be calculated. To avoid the tedious of manual calculation, a software needs to be used in order to obtain the overlay thickness. To serve this purpose, a programming language has been chosen to achieve the objective of this project. Among the available programming languages, Visual Basic 6.0 has emerged as the programming language for this project mainly because it is user-friendly and easy to develop. Besides, it can also provide us the attractive user interfaces. Therefore, it can be concluded that Visual Basic is one of the most suitable programming language to be used in developing this software. By gathering the effort from various parties, the development of the computer program to obtain the overlay thickness is completed successfully. The program has been tested thoroughly and all major flaws have been weeded out. Although this program has some limitations, the good news is, the probability of these limitations to be reduced is high. All we need to do is spend some time to expand this program. The related limitation is highlighted in Section 1.4 of this report.
