Rigid pavement design - Term Paper Example pavement, which are Jointed Plain Concrete Pavement (JPCP), Jointed Reinforced Concrete Pavement (JRCP), and Continuously Reinforced Concrete Pavement (CRCP). The joints in PCC slab help in reducing the stresses due to subgrade moisture variation, temperature variation, and shrinking of concrete based on AASHTO, 1993. Moreover, to determine the slab thickness of concrete pavement, there are equation and parameters have to be taken into account. Design, Analysis, and Rehabilitation of Windows () is a software program used to evaluate the pavement structure in terms of the expected performance under design traffic loadings and given climatic environments. The rigid pavement can resist a variety of conditions for a long time and requires less maintenance provided that it is professionally laid. ; However, the need for repair is sometimes very crucial in the case of any distress. Every strategy comes with a cost and by performing an economical analysis of the alternative strategies, the cost of each strategy can be roughly estimated. The life cycle cost analysis (LCCA) is the most effective method used to approximate the cost. In the twentieth century, the cars took the lead as the main means of transport. After the Second World War, the growth in traffic, tire pressures, loads, and the higher speeds necessitated the development of pavement technology beyond designs based on experience only. Functional performance had to be defined, predicted and understood to the basis of the service that is provided to the road users in relation to the cost. Nevertheless, this performance required a structural behavior and pavement distress knowledge in relation to the time. However, this motivated the American Association of State Highway Officials (AASHO) road test. A pavement is a structure composed of structural elements, whose functions are to protect the natural subgrade, distribute the applied vehicle loads to the subgrade, and carry the traffic safely and economically.
