Design of pavements

Pavement is a structure that is made up of different layers such as sub-base course layer, base course layer, binder course, and a surface course formed with different materials such as gravel, above the subgrade soil constructed to act as a path or carriageway enabling the movement of vehicles. The surface of the pavement should possess characteristics such as adequate friction, light reflection, and drainage. The pavements are classified based on structural design into rigid pavements, flexible pavements, composite pavements, and unpaved pavements. The process of determining a suitable pavement type, its constituent layers, and its thickness is called pavement design.

4.13) A rigid pavement is being designed with the same parameters as used in Problem 4.5. The modulus of subgrade reaction is 300 1b/in? and the slab thickness is determined to be 8.5 inches. The load transfer coefficient is 3.0, the drainage coefficient is 1.0, and the modulus of elasticity is 4 million Ib/in?. What is the design modulus of rupture? (Assume that any parameters not given in this problem are the same as those given in Problem 4.5.) 4.5 has been added for reference.

A flexible pavement is constructed with 3 inches of hot-mix asphalt (HMA) wearingsurface, 6 inches of emulsion/aggregate-bituminous base, and 6 inches of crushedstone subbase. The subgrade has a soil resilient modulus of 8,000 lb/in2 , and M2 andM3 are equal to 1.0 for the materials in the pavement structure. The overall standarddeviation is 0.5, the initial PSI is 4.5, and the TSI is 2.5. The daily traffic has 1080 20-kipsingle axles, 400 24-kip single axles, and 680 40-kip tandem axles. How many yearswould you estimate this pavement would last (how long before its PSI drops below aTSI of 2.5) if you wanted to be 90% confident that your estimate was not too high,and if you wanted to be 99% confident that your estimate was not too high?
