Study and Analysis of Bitumen Mixture Incorporating with Waste Foundry Sand
International Journal for Research in Applied Science and Engineering Technology
In 20 th century India is aiming to be developed country. The backbone of any developed country is its Infrastructure facility. Now day in India lot of infrastructure projects are going on, in that the road transportation facility is a very important criteria. In recent years there is spontaneous increase in demand of good quality pavements in Urban as well as in rural areas. The construction of good quality roads is mainly depend upon the funding available for construction and quality of raw
... nd quality of raw material available for construction of road, so it very important to construct good quality roads in low budget. Due to scarcity natural resources, the cost of raw material is increasing day by day, so it is important to find out alternative material for construction of roads. Now a day's various Industrial wastes are utilized for road construction. In Kolhapur city there are lot of foundry industries, which generated lot foundry sand waste. Generally this waste is dumped in open areas. This foundry sand can be utilized for various construction purposes. Famously this is utilized in concrete. In this study the emphasis is given to use of foundry sand waste in flexible pavement construction. The focus of this study is to analyse the impact of foundry sand on properties of bitumen. In this study we have carried out standard testing of bitumen with percentage replacement of foundry sand to compare the properties of normal bitumen and foundry sand mix bitumen. 2%, 3% & 4 % foundry sand replacement is done and tests are carried out as per standard procedure. After conduction of tests it has been found that the properties of bitumen are changed and those are not as per IS requirements. Only the value of flash point and fire is within the range specified by IS codes. VI. CONCLUSION A. The standard reading of penetration test on normal bitumen as per IS:1203-1978 range between 80-100mm. observed reading in percentage replacement of foundry sand is greater than the 38% of normal bitumen B. The standard reading of softening point test on normal bitumen as per IS:1205-1978 range between 35-70 ºC. observed reading in percentage replacement of foundry sand is greater than the 70%of normal bitumen C. The standard reading of ductility test normal bitumen as per IS:1208-1978 range between 50-75cm. observed reading in percentage replacement of foundry sand is lesser than the 59% of normal bitumen. D. The standard reading of flash and fire point test on normal bitumen as per IS:1209IS: -1978 Range between 65°C -107°C. Observed reading in percentage replacement of foundry sand is similar to the normal bitumen. E. From result and analysis it has been found that after replacement of foundry sand bitumen changes its properties significantly and results are not as per standard.
