This course will discuss several important subjects for road Engineers. This course will discuss mainly the method of designing the structure of a pavement. The design of a pavement structure means determining the layers of a pavement, furthermore, determining the thickness of each layer. The purpose of a structural design of Pavement is to determine the suitable pavement structure that can sustain the anticipated traffic volume for the design period. In this course, you will learn the design of Pavement by the use of CBR method and AASHTO method. The design of Pavement by the use of AASHTO method will include determining a set of parameters such as ESAL which is a number calculated to represent the traffic carried by the pavement during the design life, also, resilient modules, reliability, standard deviation and other parameters are determined to calculate the structural numbers of different pavement layer. SN is used to determine the thickness of different pavement layers. You will see the process of determining all these parameters to find the thickness of Pavement layers. This course will include a various examples to simplify and enhance the understanding process. Also, it will include several quizzes and assignments.This course will also contain a section about the traffic survey which will include various subjects such traffic count and the methods of conducting traffic count and how the ADT is determined from the traffic count, also, it will include a lecture about the axle load survey and the method of conducting axle load survey, also, it will include lectures about the tire pressure, design life of pavement, classified count, etc. This course will also, include a section that briefly explain the construction of a pavement and the component of a flexible pavement. This course will briefly discuss the procedures of constructing Embankment, laying and compaction of granular subbase and roadbase layers. Also, the procedure of laying asphalt and the types of asphaltic concrete courses. In conclusion, this course will focus on designing and construction of a flexible pavement. At the end of this course, you should have a sufficient knowledge of how the pavement is constructed, the different pavement layers and properties of each layer. Also, how to design a pavement and how to analyze the traffic survey data to determine the ESAL and then determining the thickness of different pavement layers.
