The conduct of the rigid pavement is now being extended and further research is required to enhance the concrete's properties. To solve this issue, researchers concentrate primarily on certain materials that can substitute conventional materials in the construction of pavements. This paper focuses primarily on partial cement substitution in rigid construction of the pavement. Here we are replacing cement with fly ash and lime. These materials have a reduced carrying capacity and poor settling characteristics as their main drawbacks. The concert of these materials can be greatly enhanced by the implementation of reinforcing element to boost its compressive and bending strength for superior durability.The use of natural materials such as jute, coir and bamboo, as fly-ash and lime reinforcing materials, are very cheap and readily accessible in large quantities, with the greatest tearing intensity and even under wet conditions. We substitute cement partly with different portions of fly ash, lime and coir fiber in M30 concrete in our project. Workability tests such as slump cone tests and strength tests such as compression tests and bending strength tests were performed to determine the behaviour of concrete mix.

INTRODUCTION The pavement consists of different layers of materials treated above the subsoil, the basic purpose of which is to transfer the load applied to the subsoil. The paving system shall be provided with good surface quality, adequate skid resistance, desirable light reflecting ability and low noise emissions. The main goal is to ensure that the stress caused by wheel loads is properly reduced. The rigid paving system consists of a concrete surface on which a granular or sub- bases may be built. The availability of a good foundation or sub-floor layer below the concrete surface increases pavement life and is also cheaper in the longer term. Thanks to its rigidity and its high strength, a rigid pavement appears to spread the load over a very large subgrade area and the slab itself provides a significant portion of the structural energy. The rigid flooring is used for heavy loads and can be built over relatively small subgrades. One of the biggest issues in the production and recycling sectors is the disposal of waste materials. Ash is an easily-accessible by- product – particularly in India, because of the coal consumption in power generation. When this supply becomes more evident, the need for economic paving materials which have a low impact on the environment is increasingly growing. Consequently, Ash is considered in this article as an alternate subbasic material. As a powdered material, because of its pozzolanic properties and consistency with cement, it can fullfill the requirements of a cement-based sub-base. Instead of cement, lime can also be used to give similar long-term strengths. The addition of steel reinforcement increases the strength of concrete significantly and leads to concrete with uniform tensile properties but it must be monitored for the development of micro splits within a ceiling structure. In general, fibres are used as a solution for creating concrete in order to improve their flexural and tensile strength.
