Abstract
This investigation is focused on the conversion of waste plastic into modified pavement interlock block (Bitumen: quarry dust: coarse aggregate: rice straw ash: waste plastic:: 5% by weight of aggregate mix : 1:2:2% by weight of aggregate mix : 8% by weight of Bitumen) for Mathura Vrindavan city. The aim of this work is to reduce the rapid accumulation of waste plastic at religious places/ tourist spot by throwing the PET bottles in Mathura Vrindavan city. With the application of these experimental results, can make economical and environment friendly paving block. For each 6.7 no. of paving block, 1 PET bottle (38gm) of 1lit volume consumed hence in 10m2 areas 55.37no. bottles can be utilized. From Marshall Stability- Flow value test, 8% of PET plastic is optimum value which can use in manufacturing of modified paving block with 80/100 grade of bitumen. The average compressive strength of these blocks at 3 and 7 days is15.94MPa and 24.2MPa and the water absorption value is approximately 0.27%. In the presence of sodium sulphate (250gm in 1lit water) loss of weight is around 7.7%. It was estimated that the manufacturing cost of designed paving block is 12Rs. whereas concrete paving block of same size is Rs. 17. Hence its cost quite low as compared to conventional block.
