Design a granular pavement with 30mm thick bituminous surfacing for a 4 lane road (2 lanes each way) Urban Arterial with the following characteristics. The average annual daily traffic of the road is 10,000, among which C% are heavy vehicles. Assume reasonable values for direction factor and lane distribution factor based on the relevant Austroads guideline. Consider 2.7% growth in annual traffic volume during the design period of (19+C) years. Use VicRoads Code of Practice RC 500.22 for the parameters required for the determination of the design traffic. Further, assume that the subgrade is a sandy clay soil. Note that the project requires the use of dense graded asphalt for the bituminous surface. State any other assumptions you make with justification. In designing the pavement thickness, you are advised to optimise the thickness of the base and subbase layers with respect to construction time and expenses. State in your report what considerations you made to do this. For the value of 'C' - take the last digit of your student number and add 2 to it (example: if your student number is S1234567, you take 7 and add 2 to it, so your C = 9). Ensure that you take the correct value from your student number. Penalties apply for incorrect use of the value. Present your results with detailed calculation steps and graphical illustrations, including the use of any charts from Austroads guides. Clearly show on the charts, how you have read the values of CBR, Design Traffic, and pavement thicknesses. Schematically draw the different layers of the pavement with the names and thickness of each layer - present your drawing. Clearly state your final answer.
