DESIGN OF RIGID PAVEMENT AND ITS COSTBENEFIT ANALYSIS BY USAGE OF VITRIFIED POLISH WASTE AND RECRON POLYESTER FIBRE M. T. S. Lakshmayya Civil Engineering Department, G.M. R. Institute of Technology, Rajam, Andhra Pradesh, India G. Aditya Civil Engineering Department, G. M. R. Institute of Technology, Rajam, Andhra Pradesh, India ABSTRACT A country can achieve sustainable and rapid growth in all fields by improving its connectivity and transit systems. Connectivity of people to resources by improved transit mechanism results in improved living standards. Apart from other means, the major part of connectivity of any country is through road systems. Well designed and maintained pavements provide better and long lasting service. In India, all the major road systems are designed as flexible pavements only, because of their ease of construction and less time it takes to be opened to traffic operations. The major problem with flexible pavements is their design life and high maintenance costs. Also, globally reducing petrol reserves, which are used for bitumen and asphalt production are also increasing the need for alternatives. To tackle these problems, rigid pavements can be constructed. Although the cost of construction of rigid pavements is high, its long life, high load carrying capabilities and low maintenance cost will balance the initial cost aspect. Recently, many studies are being conducted on different pozzolanic admixtures which can be used as partial replacement of cement in rigid pavements, thereby reducing its cost and enhancing properties of the mix. Here, an attempt is made to reduce the construction cost of rigid pavements by incorporating Vitrified Polish Waste (VPW) as partial cement replacement in proportions of 5% for M40 grade concrete. Further, to enhance flexural properties of pavement, Recron fibre is added to optimum VPW in increments of 0.1%, then after C.C pavement is designed for two lane two way national highway and cost benefit analysis is performed.

1. INTRODUCTION After understanding the importance and necessity of rigid pavement construction many researches and studies are conducted in this aspect. The studies mainly focused on improvement of mechanical and durability properties of concrete by usage of various additives, admixtures and fibres to concrete mix. These admixtures are used as partial or full replacement of cement along or without fibres. The fibres used are also available in different types like steel, glass etc. Studies are also conducted on them individually as well as compositely.Luiz Renato, Steiner Adriano et.al [2001] studied, the properties of sludge obtained from polishing of ceramic tiles. X-ray diffraction, X-ray fluorescence, laser diffraction and several other tests were conducted to study physical and chemical properties of this sludge. Also, recommended its usage as Supplementary Cementious Material (SCM) in various engineering constructions. Jay Patel, B.K. Shahet.al [2014] in his literature analysis about ceramic waste inclusion in concrete making concluded that, ceramic products have good pozzolanic activity because of their manufacturing temperature and its usage is good for economy and environment. He also concluded that, cost of construction can be reduced by 2030% for higher grades of concrete by its usage. Electricwala Fatima, Ankit Jhamb, Rakesh Kumar et al [2013] have investigated on M35 grade of concrete by replacing up to 30% of cement with ceramic dust and observed an increment in compressive strength, flexural strength. The results showed an increase in compressive strength by 3.9% to 5.6% by replacing 20% cement content with ceramic dust. Ponnapati Manogna, M. Sri Lakshmi [2015] investigated on partial replacement of cement by tile waste in M30 grade of concrete in increments of 10% up to 50%.Compressive, tensile and flexural strength tests were conducted for 7, 28 and 56 days respectively and suggested that a replacement up to 30% can be made without compromising on design strength. However, optimum results for compression,tension and flexure strength were attained at 10% replacement. Abhinav. S. Pawar, K.R. Dhabekar [2014] investigated on addition of waste material (GGBS) and steel fibresin M40 grade concrete for rigid pavement and compared with normal concrete of M40 grade.After testing it was found that, 30% GGBS is the optimum replacement for M40 grade of concrete but, flexural strength decreased by increasing percentage of GGBS, so as to increase flexural strength, steel fibres of two different aspect ratios (7560 & 7530) were used. Steel fibres were added in concrete by 1% of total weight of concrete with different proportions. Nandish S.C, Ajith B.T et.al [2015] studied about strength enhancement of conventional concrete with addition of Coconut fibres and polypropylene fibres. The coconut fibres of various proportions like 1%, 1.5%, 2%, 2.5% and polypropylene fibres of proportions of 0.4% by volume of concrete were used in the M40 grade concrete mix tests to determine the mechanical properties of concrete up to 7, 28, 56 and 90 days. Use of fibres tends to enhance the flexural strength of the mix. Fibre mixed concrete has higher value than that of the control mix. For 2.0%CF and 0.4%PF of fiber, flexural strength found to be 14% higher than that of control mix concrete. Mehul. J. Patel, S. M. Kulkarni [2013] studied effects of poly propylene fibres on M40 grade of concrete by adding in proportions of 0.5%, 1%, and 1.5% and investigated for compressive, flexural and split tensile strengths and reported an increase in above parameters when compared to conventional concrete. Vipul. D. Prajapathi, Nilay Joshi et.al [2013] experimented on usage of fine aggregate replaced by used foundry sand in proportions of 0%, 10%, 30% and 50% for M20 grade of concrete and studied their mechanical properties. He concluded that, maximum compressive and flexural strengths are achieved at 50% replacement of natural fine aggregate with used foundry sand and designed a pavement for 3000CVPD flow. As a part of such studies, usage of Vitrified Polish Waste (VPW) along with recron polyester fibre is studied in this experimental investigation. Ceramic industry is extensively growing with the infrastructural needs of the present world and waste generated is also increasing rapidly there by incorporating these wastes in pavement construction will also help environmentally. A good study on Indian standard codes for laboratory sampling, and testing of concrete and materials used is also done before proceeding into testing phase, which includes the following codes (IS: 10262-2009 , IS: 456-2000 ,
