Temperature-modulated differential scanning calorimetry has been employed to analyze the structure-related thermal properties of petroleum bitumen. This method enables one to distinguish between “order–disorder” and glass transitions, thereby making it possible to monitor and identify structure-related phase transformations, the signals from which are invisible or overlapped in the thermograms of conventional differential scanning calorimetry. Bitumen has been shown to be a colloidal disperse system only under certain temperature–time conditions. Its dispersed phase may be represented by aggregates of two types with colloidal sizes. Saturated hydrocarbons form a solid crystalline phase in accordance with the regularities of first-order structural phase transitions and nucleation mechanism of phase separation. Asphaltenes and resins form a solid amorphous phase for a relatively long time as a result of a structural relaxation glass transition by the spinodal mechanism of phase separation. 相似文献

The compatibility of oxidized bitumens of types I and III with blended olefinic thermoelastoplastics was studied by calorimetry,
viscometry, and atomic-force microscopy. Improvement of process characteristics of modified products based on bitumens is
asssociated with different mechanisms of formation of their structure. 相似文献

Optimal concentrations of the mixed polyolefin modifier of TPM grade, necessary for introduction into bitumens with various disperse structures for obtaining bitumen-polymer compounds meeting the GOST (State Standard) requirements to roofing materials, were determined. The role of the crystalline phase of the polyolefin in determination of the quality of bitumen-polymer compounds was examined. 相似文献
