Laboratory studies on cigarette butts with bituminous concrete.

civil engineering

Cigarette consumption is on the rise globally, the amount of littered cigarette butts is also increasing the environment According to estimations from Euromonitor International over 5.7 trillion cigarettes were consumed worldwide in 2013; and, each year, an estimated 4.5 trillion butts from the annual cigarette consumption are deposited somewhere in the environment. The objective of our project was to incorporate these cigarette butts in bituminous concrete (sma) in varying percentages of 2%, 4% and 6% to carry out lab tests as per mort&h specification and know whether it satisfies the standards. In this project only the coarse aggregates were partially replaced by cigarette butts (CBs) and the quantity of fine aggregates was maintained constant. Bitumen of class 60/70, OPC 43grade were used. Preliminary tests were conducted on aggregates and bitumen and Marshall stability test was conducted to study the strength parameters after incorporation of cigarette butts.
