Abstract

This study aimed to evaluate the possibility of using Fourier Transform Infrared (FTIR) spectroscopy to track binders produced by three different plants: plants A, B, and C. The work included the quality assessment of 80 bituminous materials graded as BND 70/100 and 100/130 according to GOST 33133 (Russian interstate standard) and chemical analyses using FTIR spectroscopy. FTIR analyses were conducted before and after short-term ageing in a Rolling Thin Film Oven Test (RTFOT). Thus, the number of binder samples was multiplied by two (2) for a final total of 160 infrared (IR) spectra. All infrared spectra were normalised to ensure the reliability of results, and the standard deviation and variance coefficient were included. The principal purpose of the present work was to track the origin and the ageing extent of the bituminous binders under study.

Highlights

The traditional type of organic binder is petroleum bitumen or petroleum bituminous materials [1]
Studies using IR spectroscopy are divided into two parts: visual analysis of IR spectra and calculation of spectrometry indices with the interpretation of the data obtained
The binder tracking is topical as road projects are often supplied with various bituminous materials from different manufacturers and dealers

Summary

Introduction

The traditional type of organic binder is petroleum bitumen or petroleum bituminous materials [1]. Improving or optimising the physicochemical characteristics of bituminous materials is a challenge for the scientific community today in order to meet the modern requirements of our society or our civilization. Bitumen production technology differs from region to region depending on ecological, climatic, and sanitary conditions or requirements [2]. The technical specifications for the quality of bituminous materials produced in leading countries such as the United States of America, China, Canada, Spain, the Russian Federation, and France differ. Road traffic density, and the technology used to produce bituminous materials contribute to these differences [5,6,7]
