Research of Oil Road Bitumen Modification with Low Density Polyethylene

Abstract

The aging of bitumen in the asphalt concrete pavement inevitably raises the question of the possibility of restoration of its regeneration characteristics. In general bitumen is classified as road bitumen, building bitumen, roofing bitumen, insulation bitumen, special purpose bitumen and others. Road bitumen is most produced (70-80%) and intended for the production of all major types of construction and repair of road works, and also liquid bitumen intended to prolong the season of road works. A promising method to improve the quality of bitumen and road coatings is using the polymeric modifier, such as polymeric waste and secondary polymers such as polyethylene, polyethylene terephthalate, atactic polypropylene in bituminous compositions. Modifying bitumen with polymers enhances its elasticity, strength and heat resistance at elevated temperatures. Increasing the crack resistance of road surfaces, increases the lifetime. This article reviews the applications of the polymer components to improve the structural and mechanical properties of bitumen. The qualitative characteristics of bitumen can be restored with recycled polymeric materials such as polyethylene. Using polyethylene in the road mix composition improves the physical and mechanical properties of bitumen by improving the adhesion of bitumen with mineral components. This allows to considerably reducing the consumption of bitumen, which in turn enables to utilize a large-waste of polymer.

Waste plastics in asphalt concrete: A review

“…This review is not the first review of this topic. [8][9][10][11][12][13][14] This review differs in that the review is written for a readership unfamiliar with asphalt and hence particular attention is spent defining terms for tests, and, as much as possible, confusing nomenclature is avoided. Further, the clear division between plastics that melt and those that do not is unique to this review versus other reviews.…”

Characteristics of Asphalt Binder and Mixture Modified With Waste Polypropylene

“…For instance, the impact of temperature differences between summer and winter, the load deformation and so on. This results in the fact that pavement service life is decreased [1]. Road pavements have also thermal susceptibilities and often experience thermal cracking in cold weather and creep and distortion in high temperature regions [2].…”

Modification of Bituminous Binders With Petrochemistry Waste

“…Низкомолекулярный полиэтилен (НМПЭ) представляет собой побочный продукт производства полиэтилена высокого давления, относится к классу полиолефинов; гидрофобное вещество от белого до серого цвета, обладающее высокой адгезией к различным материалам; устойчив к воздействию химически агрессивных сред, имеет высокую температуру вспышки (выше 250 °С) 3 [5][6][7]. НМПЭ состоит в основном из олефинов с прямой цепью из 10-20 атомов углерода, кроме скелетных СН2-групп, содержат ненасыщенные связи и концевые СН3-группы.…”
