Abstract

Libya has a relatively mild climate to the north and a desert climate (hot - dry) to the south، where desert climates are characterized by high temperature and low rainfall as well as the large temperature changes between night and day. Therefore، there were many problems in paving، which resulted in poor performance of flexible pavement in road projects in these areas. The most important of these problems is the early hardening of the asphalt، resulting in early cracks that lead to the early collapse of the pavement.

Due to the futility of maintenance operations on some of the damaged roads، it was necessary to find alternative techniques to address this phenomenon. Hence the idea of adding materials for asphalt or asphalt mix to develop and improve their performance.

The use of waste materials in asphalt pavement is useful for finding an alternative solution to increase its age and reduce environmental pollution as well as reduce the economic cost of road construction and maintenance cost. One of these wastes is polyethylene water bottles produced in large quantities. In this work، polyethylene terephthalate was used to verify the possibility of using polyethylene water terephthalate as a polymer added to the asphalt mixture to overcome pavement problems. Five different percentages of plastic water bottles (4%، 6%، 8%، 10% and 12%) were added to the optimum asphalt weight for Marsh preparation For. The results indicated the optimum improvement content to be (8%) for waste water bottles improved for asphalt mixtures where it was found to give maximum stability، rigidity، asphalt-filled spaces، and minimum air voids، compared to the improved mix.
