| Abstract | ||
| The growth in various types of industries together with population growth has resulted in enormous increase in production of various types of waste materials, world over. The creation and disposal of non-decaying waste materials have been posing difficult problems in developed as well as in developing countries. The efforts to find useful applications of some of the waste products in highway construction have given encouraging results. The use of Tetra-Pak (TPA) containers to pack food of various kinds including milk, juice, meat, etc. has become a common practice. To produce packaging materials, TPA uses paperboard (73%), plastic (22%) and -for aseptic packages- aluminum foil (5%). However the disposal of the Tetra-Pak in large quantities has been a problem and is of great concern, particularly in big cities. In case it is possible to find useful application for the waste TPA, there will be substantial scrap value for this waste product and therefore they will be collected and sold by interested persons, instead of being littered or thrown out in the dust bins or into the road side drains. The present study investigates the benefits of using shredded Tetra-Pak in binder layer flexible pavement mix. A (1-6)mm in particle pieces of TPA had been added. The mix had been tested by Marshall testing method. Mix volume relationships, Marshall Stability and flow with the different percent of shredded TPA were recorded. A control binder mix is used with (5)% asphalt content for comparison and the same asphalt content used for all specimens. The research concluded that using TPA in the range of (1-1.5)% in HMA increase the Marshall stability, flow and air voids and decrease in voids filled with asphalt. For (2)% there was decrease in stability, air voids and voids filled with asphalt (VFB) and increase in flow. In (3-above)% the mix start scattered in the test. | ||
