Abstract
The object of the study includes modified road bitumen and geotextile materials, for the synthesis of which recycled PET and CNT were used. The production of new materials is caused by the need to improve their technical characteristics, which, in the end, should have a positive impact on the properties of composites based on them. The main method of research is an experiment. During the experiment, a grid of compositions of new materials and laboratory technology for their production were developed, their basic properties were studied. According to the results of the study of the basic properties of new materials there is an improvement of their basic properties up to 10% compared to the original ones.
Highlights
At present a major challenge facing builders is the efficient use of material resources to reduce costs
The goal of this study is to develop new makeup of modified bitumen due to the introduction of the organic binder of carbon nanotubes (CNT) and recycled polyethylene terephthalate (PET), as well as technologies for the introduction of complex modifiers
Cointroduction of PET and CNT made it possible to obtain material with the indicators presented in table 3 due to the synergetic modifying effect
Summary
At present a major challenge facing builders is the efficient use of material resources to reduce costs. In this context application of secondary resources, especially in areas with a shortage of traditional construction materials is currently important. Waste polyethylene terephthalate results from manufacturing processing of raw materials into products. Every year Russia produces about 300-400 thousand tons of polyethylene terephthalate waste. The cost of PET waste disposal remains quite high [10, 21]. A common method of disposal of household waste plastics is incineration. In the estimation of various experts up to 40% of plastic waste is burned
