Plastic Awareness Essay

PLASTIC ROADS
Abstract:-
Plastic today has become an inseparable part of human life. All sections of society today rely on them to meet their daily chores. Plastic, now days have higher durability, which also tempts people to use them on large scale, hence increasing their popularity. Huge amount of waste generated due to plastics can no longer be ignored, apart from being non bio-degradable which harms the environment, plastic waste also leads to serious clogging of sewerages causing health concerns, polluting underground water, destroying aesthetical look of place etc. Inspite of having so many harmful effects, we cannot afford to completely eliminate plastic from our daily life, instead we are compelled to find effective ways of dealing

Skid resistance: This provides a measure of frictional property, micro texture of surfaces, either in the field or in the laboratory. The quantity measured with the portable tester has been termed ‘‘Skid-resistance’’ and this correlates with the performance of a vehicle with patterned types braking with locked wheels on a wet road at 50 km/h. The skidding nature of a road, particularly in wet condition mainly depends upon the surface texture of the road layer. The skid resistance is measured as a skid number and it is then compared with reference value. Lesser the skid number more is the resistance. For a well performing road, the prescribed skid number should be less than 65. Tests showed that skid number of the plain bitumen road is around 76 which is a higher value. For a plain bitumen road the water absorption capacity is high which turn makes the road more slippery. Other important reason for road slippery is the excessive bleeding of bitumen during summer, in case of plain bitumen the softening point is reduced as the performance of the road prolongs which in turn results in over bleeding and smoothening of the road surface, resulting in increased value of skid number. But in the case of plastic tar road, it absorbs less moisture and reduces slippery, and due to small modification in the basic properties of bitumen there is no bleeding hence skid number for the plastic tar road is
