Gasoline is widely used as a powerful organic solvent to remove asphalt residuals in road engineering applications; however, it is also known as a non-renewable fuel resource. This research aims to employ mineral powder to mitigate the consumption of gasoline in asphalt binder cleaning process, and evaluate its mechanism, environmental and economic benefits. Based on X-Ray Diffraction (XRD) spectra, X-Ray Fluorescence (XRF) spectra and Atomic Absorption Spectroscopy (AAS) detection, the microstructure and composition of mineral powder was investigated after adsorbing asphalt components from gasoline solution. Fourier Transform Infrared spectra (FTIR) were used to calculate the adsorption efficiency. Moreover, the assessments of environmental and economic impacts of investigated approach were evaluated quantitatively. The results indicated that the interactions between mineral powder and asphalt binder have not changed the crystal phase, and the rough interface of mineral powder could adsorb approximately 4% asphalt binder from the gasoline solution according to the detection of Zn. The comparative analysis, regarding cost-effectiveness and environmental impacts, demonstrated that once 1 kg asphalt adsorbed by mineral powder, recycling gasoline with mineral powder, could reduce costs by 80% (CNY 57.10), energy use by 97% (352.88 MJ) and equivalent CO2 emission by 93% (23.95 kg).

In the last years, many researchers studied production of warm asphalt concrete by usingorganic, chemical and water-bearing additive )synthetic zeolite). The purpose of this research is to study theeffect of Syrian natural zeolite on the physical and rheological properties of asphalt binder and verify ofusing it to produce warm asphalt concrete (as a binder modifier or as additive to asphalt concrete), in additionto economic benefits by saving on the cost of synthetic zeolite. In this study, natural zeolite characterizationhas been investigated via X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD) and Thermal Gravimetricanalysis (TGA). Natural zeolite was added to asphalt binder with different percentages (3, 4, 5 and 6%) byweight and to determine the effect of natural zeolite on properties of asphalt binder, penetration at )25(°∁,softening point, ductility, viscosity at (110, 120, 135)°∁ and RTOFT tests were carried out on both modifiedand unmodified aged asphalt binder with natural zeolite. According to the test results, it has been seen thatthe addition of natural zeolite improves properties of the asphalt binder and an increase in its resistance tofatigue, and do not make a substantial difference on the workability of the asphalt binder. So the effect ofthe mixture of natural zeolite additives on the workability could not be predicted on asphalt binder, thereforethe direct effect of additives should be studied on the asphalt mixtures.

Asphalt binder research papers characterized by X-ray diffraction are reviewed. The Xray results reveal the aromaticity and crystallite size parameters of asphaltene in asphalt binders as reported in the research literature. The research data is discussed in terms of asphalt molecular structure on a length scale, methodology, and petroleum oil fields. Box plots and summary statistics created for each parameter are compared and discussed as they relate to eleven data sets from various asphaltene-crude-oil-geological-regions.

ABSTRACTAsphalt concrete is the most common material for highway and motorway construction. The quality of asphalt is determined, to a large extent, by properties of asphalt binder. Fillers, which are mineral powders from carbonate rocks and aggregates fines, such as limestone and dolomite, are often used in the composition of bitumen mastics affecting the performance of asphalt.This article explores the feasibility of using the fines of aluminosilicate sedimentary rocks as fillers. These materials are composed of clay minerals, which change their properties upon the contact with water. Normally, the use of such fillers is restricted because of poor water resistance and swelling of asphalt concrete. In order to improve the performance of these fillers, the thermal modification at moderate temperatures of 500–600 °C has been proposed. Such treatment provides sufficient structural stability of obtained materials and results in the reduction of water absorption of asphalt, improved water resistance (up to 2.5 times) and also, in reduced swelling (up to 9 times).It has been demonstrated that improvement in the filler performance can be achieved by a heat treatment. Such treatment induces changes in the mineral composition and converts the structure of clay minerals into the frame structure of zeolite, as confirmed by X-ray diffraction and infrared spectroscopy. Due to thermal treatment, there is a change in the acid-base properties of the surface of the filler, which is reflected in the profiles of the main adsorption centers. As a result, due to chemisorption, the modified aluminosilicate fillers are able to interact with bitumen. The application of new filler materials in asphalt concrete enables to enhance the performance.

Abundant of waste cooking oil (WCO) production can cause prominent adverse impact and threat to the environment if not properly managed and disposed. Therefore, recycling or reusing WCO in modified asphalt binder is considered as an effective utilisation and environmental benefits. Hence, this study was to evaluate the chemical characteristic of untreated and treated WCO in modified binder through X-Ray diffraction analysis. The results indicated that the amorphous structure was present in the control and modified binders with untreated and treated WCO. The flat trends tabulated in XRD graph for modified binder depicted the uniform dispersion and homogeneous solution was achieved between the untreated and treated WCO with the asphalt binder during mixing process.

SummarySeveral types of microscope-mounted drills have been described in literature to obtain pure mineral material from thin sections or polished sections (e.g. Granigg, 1915; Moritz, 1929; Haycock, 1931; Russanow, 1937; Machairas, 1967), but all of them appear to be of limited mechanical stability and reliability. This paper describes an improved drill to extract under the microscope minute quantities of pure material from thin or polished sections. The drilling is performed in a liquid (silicon-oil) to minimize loss of the drilled-out mineral powder. With the help of a micromanipulator the liquid, together with the borings, is drawn up into a microcapillary tube (less than 30 µm in diameter) made of Lindemann glass. For identification of the mineral powder the microcapillary is mounted in a Debye-Scherrer X-ray diffraction camera.

The addition of different proportions of modified pitch and phenol residue to coal blends were co-carbonized in an experimental 40kg coke oven. X-ray diffraction (XRD) patterns of the coke indicate that with increasing of modified pitch and phenol residue in coal blends, the crystallite height Lc increases, microcrystal layer distance d002 decreases. It demonstrates that the microcrystal structure of coke can be improved by adding modified pitch and phenol residue, and modified pitch is more effective than phenol residue to improve coke quality.The overall objective of the study is the utilization of lower rank coals and by-products in coking plants,in the making of metallurgical coke. It would have obvious economic benefits.

In this paper, sodium bentonite (BT) and organically modified sodium bentonite (OBT) are used to reinforce and modify asphalt binder. The microstructures of the reinforced asphalt binders are investigated using transmission electron microscopy (TEM) and wide angle X-ray diffraction (WAXD). Two models for the microstructure of the BT and OBT modified asphalts are suggested considering the colloidal structure of the base asphalt binder. The physical properties of the modified asphalt binders were studied.
