“…In a recent study, it was confirmed that waste plastics used in bituminous mixes, have no negative impact on the environment (leachability) and / or worker safety (harmful fumes) [13]. several research works found that heating of waste in the range of 109 to 180 C in controlled conditions are not emitting toxic gases, emission will start if we heat beyond 270° C [14]. However, in the literature, only little research has been carried out on the use of polymers derived from recycling (plastic waste) in RAP material, although the majority of the work focused on the use of polymer granules of a few millimeters (1 to 4 mm) to modify bitumen by wet method [15].…”

This paper aims to examine physical and mechanical performances of a Reclaimed asphalt pavement (RAP) material reinforced with 5 to 15 mm size sheets of plastic waste. The three types of plastic used in the study are: low density polyethylene (LDPE), high density polyethylene (HDPE) and polyethylene terephthalate (PET) with 1%, 1.5%, and 2% dosage by weight of aggregates. Obtained Duriez test results testify to a 9% to 30% improvement in moisture resistance for all types of plastic compared to virgin mixture while for LDPE waste plastic type workability test attests an acceptable compaction condition for RAP material with less than 1.5% of waste plastic. Nevertheless, it has been noticed an increase in void index and compaction difficulties starting from 1.5% dosage, resistance to rutting has also improved with the addition of waste plastic, an improvement in fatigue strength was also observed particularly at 2% dosage.

“…Непрерывное накопление пластмассовых изделий на свалках может привести к серьезным экологическим проблемам. Неправильная утилизация пластиковых отходов оказывает негативное влияние на экологию и здоровье человека из-за многих причин: полимеры имеют повышенные свойства пожароопасности, иными словами при сгорании они плохо поддаются тушению и выделяют токсичные вещества; токсичные вещества из сжигаемых полимерных материалов могут мигрироваться в атмосферу, литосферу и гидросферу [6][7][8]. В этой связи, многие страны ввели запрет на выбрасывание использованных полимеров, и начали их вторичную переработку.…”

It is proposed to use plastic waste as bitumen modifiers with a special emphasis on recycled plastics. The potential use for improving the characteristics of bitumen and durability of roads is being considered. For the preparation of modified bitumen, it was used the BND 100/130 bitumen produced by LLP "JV CASPI BITUMEN" (Kazakhstan). Polymer household waste based on plastic bottles was used as objects of the research. Polymer waste was obtained by mechanical recycling. The main physical and mechanical characteristics of the modified bitumen were determined after routine tests, penetration and plasticity, softening temperature, Fraas brittleness temperature and microscopic analysis. The morphology of the modified bitumen was studied using scanning electron microscopy. An original formulation of the polymer-bitumen binder with improved performance characteristics compared to petroleum bitumen has been developed. The introduction of used polymer waste as a modifier does not require the installation of an additional homogenizer (colloidal mill), and there is no need to introduce a plasticizer to achieve the desired uniformity of the system and required by the Kazakhstan standard PMB 40 and PMB 90. Thanks to the use of this technological solution, it is possible to level the problem of disposal of household polymer waste with the polymer-bitumen binder production. This polymer modifier is characterized by low cost of its production. The advantage of the used polymer additive is the stage of polymer preparation - the process of joint chemical destruction of secondary polyethylene terephthalate in the presence of a highly elastic styrene-butadiene-styrene polymer to inhibit the delamination of polymer components in bitumen, due to which the problem of manufacturing high-quality homogenization of the product is solved.

“…According to statistics in Europe, about 38% of plastic waste goes to landfills, of which 26% are recovered, and 36% are recycled to obtain alternative energy sources. This shows that the largest amount of plastic waste is still sent to landfills, which is a consequence of the lack of free space in them [ 5 , 6 , 7 , 8 ].…”

Nowadays in the world, due to the constant desire for recycling, many countries are considering the use of recycled plastics on roads. Modification of bitumen for roads in Kazakhstan is considered one of the most suitable and popular approaches. This paper presents the results of research on the modification of bitumen by recycled plastics from waste materials. The paper describes the details of the use of plastic waste as bitumen modifiers, with a specific focus on recycled plastics and how they can potentially be used to enhance bitumen performance and the road durability. The main physical and mechanical characteristics of the modified bitumen were determined after routine tests, penetration and plasticity, softening temperature, brittleness temperature on Fraas and microscopic analysis. The morphology of the modified bitumen was studied using scanning electron microscopy. The results confirm that the modified bitumen complies with the requirements for polymer-bitumen binder of Kazakhstani standards and is suitable for the production of modified bitumen by its physical and chemical characteristics.
