Abstract
For the development of any state, transport facility is an accelerator admixture in economy. Past days material would be transported on the animals and other time taking facilities. After that done some new innovation like water facility, air facility for the transport and then road transport facility were started. The main property of pavement for its long life durability will be its material property. The main material are used in making pavement is depends on the type of pavement. For the rigid pavement aggregate, sand and cement are the main material with admixture. And the flexible pavement the binding material is asphalt, aggregate and filler material will be sand and cement.
There are many types of waste material are used in the flexible pavement to reduce the percentage of asphalt and aggregate therefore cost of construction will reduced. Waste plastics are used in this study in the replacement of bitumen content. The total reduction of asphalt is 7% with waste plastic (WP). The waste plastic is converted into fine particles and covers the aggregate with hot waste plastic before applying the bitumen coating. The percentage of bitumen content (BC) is 4.5%, 5%, 5.5% and 6% is used for the experiment. The gradation of aggregate (13.2mm -6mm), aggregate (6mm-0mm) is done with 7% waste plastic. The optimum bitumen content (OBC) is used 5.48% with 7% WP. Water absorption test is carried out of CA and FA is 0.54% and 0.85% respectively.
Loss angels’ aggregate value test and specific gravity of bitumen is observed 20.05 % and 3.05. The water absorption of dry bitumen mix material is carried out 0.81% which is nominal value, is should me not more than 2%. The aggregate impact value (AIV) is calculated as 14.63% of aggregate (13.2mm -6mm) which 7% of waste plastic.
Waste plastics is good adhesive material for construction work, it can be also used in other types of construction work as replacement of asphalt and other building material. It also reduces the percentage of waste plastics and makes environment pollution free.
