Abstract

The safe functioning of the transport system mainly depends on the quality of road surfaces. Therefore, improvement of the physical and mechanical characteristics of roads will ensure the effective protection of health and safety of people engaged in this field. Consequently, modification of the physical and mechanical characteristics of road surfaces will ensure safety in the field of transport systems. Bitumen-salt mass was used as a modifier of the road bitumen emulsions and such a mass was obtained by means of destructing the chemical weapons of the organophosphorus class of compounds since they have an effect of surface-active substances. Studying of the modified road surface parameters was carried out according to the dispersion parameters and using the method of mathematical design of the experiment. As a result, the positive effect of the bitumen-salt mass on the dispersion distribution of the bitumen phase in the bitumen emulsion was determined. The proposed method of modification of the bitumen emulsions allowed us to improve the operational parameters of the road surfaces, and thus the safety of road transport systems as a whole.

Highlights

During the Cold War, large quantities of chemical weapons containing the organophosphorus class of toxic substances as the main component were stored in the Soviet Union
Various options for further utilization of wastes obtained after such destruction were considered, and one of them was using in the road construction, since roads and quality of road surfaces are the most important elements ensuring the safety and reliability of the transport system in Russia
This method provides for a two-stage technology involving the initial neutralization of toxic substances such as sarin, soman, VX-gases and obtaining of a reaction mass which is bitumenized at the second stage

Summary

Introduction

During the Cold War, large quantities of chemical weapons containing the organophosphorus class of toxic substances (sarin, soman, VX-gases) as the main component were stored in the Soviet Union. It should be noted that the amount of the bitumen-salt mass increases compared to the initial amount of toxic substances by 3.5 times. The efficiency of the bitumen emulsion is determined by the efficiency of emulsifiers, namely, surface-active substances, introduced into its composition.
