| Abstract | ||
| The quantity and type of waste being generated is growing at enormous rate. The plastic waste produced particularly in form of bags, Plates, Containers, being non-degradable and with limited recycling options poses disposal problem. An academic research aimed at probable use of waste plastic in pavement structure so as to come up with an ultimate safe disposal together with improvement in the performance of asphalt mix of road through better mix design was under taken. Preliminary investigations have indicate of RPWA (from 1.2 in (1.5 cm) to No. 200 sieve ( 0.075 cm) , in surface mix design when utilized up to (5% to 15%) by weight substitution, through the use of Box-Wilson design program in order to give an optimum condition, time of reaction, and weight percent of substitution replacement aggregate in asphalt mix. The above following variables were studied temperatures (109-206) c , time (20-60) min and weight at waste substitution (5-15) % wt. respectively. The optimum conditions were: were 172 oc, 40 min, and 10% wt RPWA. The effects of experimental variables on the properties of improved asphalt mix were studied using the Box-Wilson technique of experimental design and useful relationships could be attained. Which improved these optimum conditions give high stability of Marshall Test and low distortion with acceptable low constant wet density and uneffect dry density with these condition with high resistance to chemical solutions exposure? It is envisaged that use of RPWA in the conventional asphalt hot mix design likely to improve the surface asphalt mix performance with sustainable solution for the disposal of plastic waste. | ||
