Abstracts: A rigid pavement system consists of a number of relatively thin Portland cement concrete slabs, finite in length and width, over one or more foundation layers. When a slab-on-grade is subjected to a wheel load, it develops bending stresses and distributes the load over the foundation. However, the response of these ?nite slabs is controlled by joint or edge discontinuities. By their nature, joints are structurally weakening components of the system. Thus, the response and effectiveness of joints are primary concerns in rigid pavement analysis and design. Rigid pavement has the ability to bridge small imperfections in the sub grade. However, if it does fail, the failures take the form of rigid steps in the road grade. Each section "floats" like a boat above the sub grade and tries to level itself rather than maintain the original slope. The main drawback of flexible pavement, particularly in rolling terrain in Parbhat Chowk to K.K. Nagar, where large no. of curves exists in road alignment, the flexible pavement tends to wear off fast and creates ruts in the road surface and main problem of rain water is not properly drain for this section we have select the road path of k.k.nagar to prabhat chowk. Thus the flexible road alignment becomes unsafe and uncomfortable for road users. Further flexible pavements high maintenance cost every 5 years for laying renewal coat is a major drawback. Beside this there are some other problems of flexible pavement such as low flexural strength, low life span, less force of friction. Over this road we have taken the soil sample from every 500m over the 2km stretch. We have perform different type of test on soil base on the rigid pavement and perform it well and got result from it. In this semester we are going to perform the remaining few test of soil and going to design the rigid pavement. we are going to learn the software name street pave which is American standard software and use it in design of rigid pavement. After completion of this manually and software design with one is the economical will be selected. Our main aim of this project to built the economical and safe pavement which strength and design should be free from maintenance cost and any type of damages.
