| Abstract: | Rutting
is caused by accumulation of permanent deformations caused by repeated
applications of traffic loads and it is a stress controlled cyclic loading
phenomenon. The process of deformation of bituminous surfacing is accelerated
by increase of pavement temperature, reduction in stiffness of mix and increase
in traffic loads. The aim of this paper is to report findings of study on
increase in stiffness modulus of bituminous mixes by incorporation of waste
polymeric packaging material (WPPM) to enhance pavement performance as well as
to protect environment. This work presents studies on use of WPPM in road
construction. Polymeric poly packs are used for packaging of milk for
distribution to consumers and such bags after consumption of milk are thrown
away. These used milk bags and other high density polyethylene (HDPE) based
carry bags are used as additives in bituminous mixes. The optimum dose of these
two types of WPPM for modification of bitumen and bitumen mix is investigated.
Results reveal that optimum dose of WPPM is 0.3 to 0.4% by weight of bituminous
mix. Higher dose lead to undesirably higher stiffness of mix. Rutting of
bituminous mix can be reduced to 3.6 mm from a value of 16.2 mm after
application of 20,000 cycles, by adding optimum quantity of WPPM in bituminous
mix for road construction. Indirect tensile strength ratio further confirm
potential of these mixes in prevention of moisture damage also, ultimately
improvement of pavement performance, besides alleviating disposal problems of
WPPM for clean and safe environment. |
