Cig­a­rette butts for lay­ing roads

NBM&CW - - NEWS -

Cig­a­rette butts could be the new con­struc­tion ma­te­rial to be used to lay roads as well as build­ing ma­te­rial which can be used in dif­fer­ent ap­pli­ca­tions and light­weight com­pos­ite ma­te­rial. Re­searchers from the Royal Mel­bourne In­sti­tute of Tech­nol­ogy (RMIT Univer­sity) in Aus­tralia have demon­strated that as­phalt mixed with cig­a­rette butts can han­dle heavy traf­fic and also re­duce ther­mal con­duc­tiv­ity. The team en­cap­su­lated cig­a­rette butts with bi­tu­men and paraf­fin wax to lock in chem­i­cals and pre­vent any leach­ing from the as­phalt con­crete. The en­cap­su­lated cig­a­rette butts were thin mixed with hot as­phalt mix for mak­ing sam­ples. These en­cap­su­lated cig­a­rette butts de­vel­oped will be a new con­struc­tion ma­te­rial which can be used in dif­fer­ent ap­pli­ca­tions and light­weight com­pos­ite prod­ucts. Af­ter the suc­cess­ful ex­er­cise to use plas­tics as the build­ing ma­te­rial uti­liza­tion of cig­a­rette butts waste is an­other im­por­tant in­no­va­tive de­vel­op­ment.

In In­dia plas­tic waste has been suc­cess­fully used for con­struct­ing one lakh km of roads in 11 states. These roads are ex­pected to last for more than 10 years, claims Na­tional Ru­ral Road Agency. In this process plas­tic waste is mixed with bi­tu­men and coat­ing the mixed with stones.
