Asphalt composition, rheological

The influence of the composition of asphalt has been recognized, for many years, as being an important factor in controlling the performance of such materials. Furthermore, rheological properties have always been associated with composition but, in order to utilize compositional data effectively, more definitive correlations between composition and properties are needed (46—48). 

Distillate cut 3 obtained from bulk separation is still dark colored which may indicate the presence of small quantities of asphaltic material (20). Figure 3 indicates that it is possible that a composite of compounds, besides carboxylic acids, may be required to yield optimal recovery. In order to understand the mechanism of oil recovery, the contribution of a given individual fraction to ultra-low surface tension characteristics and the contribution of various combinations of individual fractions contribute greatly to viscosity behavior. Therefore, interfacial rheology may be dependent on the appropriate composition of the crude oil. 

Thanks to all these properties, the dolocarbonate seems promising for different applications, first of all for all the applications of traditional low density mineral fillers. This material could for instance be used as a component in thermal insulating materials like panels or foams, as a filler in mortars or plasters or concretes to decrease their thermal conductivity, as a filler in polymer or rubber compositions to improve their fire and/or mechanical properties, as a filler in paints, papers, cosmetic compositions, as a rheology modifier (viscosifying agent) in mineral slurries, glues, bitumen or asphalts, polymer compositions, as an ad- or absorbant in different applications such as water or flue gas treatment or even in the field of catalysis, as e.g. a catalyst support, or as a carrier for perfumes, aromas, active substances, medicines...
