Study of Physical Properties of Bituminous Mix Using Waste Leather Shoes in Flexible Structure
For all countries, a beneficial road network is required for industrial expansion, national operation, and as well as for socio-economic growth, due to improvement in the living level of the humankind. The utilization of roads has increased over the last few years. So, a considerable amount of construction materials are being consumed in road construction. Therefore, economically preparing of these materials is one of the most important works in road construction. As the road material is naturally available material is limited and can be found in specific places only. Road construction engineers are trying to use waste materials as construction materials to reduce road construction costs and reduce pollution from the world and as well as to save the natural source. One of that, the use of the waste leather shoes to use as a construction material for pavement. The use of crumb leather shoes in flexible pavements in the form of fillers/additives could minimize environmental pollution and maximize natural resource conservation. Crumb leather shoes made from leather and rubber (the major components of leather shoes are leather and shoe’s sole). The production of waste leather shoes is about 30.8 billion pairs per annum. (Because the present world population is 7.7 billion according to the most recent United Nations elaborated world meters). And it is day by day increasing. The average uses the life of the leather shoes are about 3months (hypothesis), and unfortunately, they are being disposed of in an environmentally unfriendly manner. This experimental research related to broad parts of waste leather shoes by (4%, 8%, 12%, 16%, and 20%) instead of bitumen VG40.
