ABSTRACT

Concrete Block Pavement (CBP) is getting popularity in areas where normal flexible pavement does not last long. Application of CBP is developing very fast for various reasons such as high resistance to deformation, durability, easy and rapid quality construction, ability to carry traffic immediately after construction, compatibility with the environment and aesthetic features etc.The structural behaviour of CBP is similar to flexible pavement. However, the performance of CBP depends upon on block shape, size, thickness, type of bedding and jointing sand, joint width.The process of manufacturing is simple and standardized. Cement concrete is a mixture of cement, sand and stone chips in correct proportions. The items are mixed in water and churned thoroughly in a concrete mixture. The process involves proportioning, Mixing, Compacting, Curing & Drying. A concrete mix of 1:2:4cement: sand: stone chips by volume are used for making paving blocks.Concrete paver blocks are used in various applications like street road, small and medium market roads, low volume roads and other construction places.Recently in concrete paver block fibers are introduced to increase strength, durability and reduction in cracks. Fibers in concrete paver block improve properties of paver block. The concrete paver block maintenance is low and economic when compared with other pavements. Experimental investigations show that compressive strength and flexural strength of Polypropylene concrete paver block is higher than the normal paver blocks. Hence it can be used in heavy traffic area and give surface resistance for longer life. By using fibers in concrete paver block, it increases resistance to impact/abrasion and greatly improves quality of construction. Therefore, paver blocks with fibers do not easily crack, break or buckle.Basalt fiber offer prospect of completely concrete. They have potential to high performance and cost effectively replaces of fiberglass, steel, new range of composite materials and product. Low cost high performance fibers offer potential to solve the largest problem in the cement and concrete industry, cracking and structural failure of concrete. They have potential to high performance and cost effectively replace of fiberglass and steel.
