PROPERTIES OF BITUMENS MODIFIED WITH ELASTOMERS

In Turkey, 95 percent of goods and passengers transportation have been made by Highway transportation system. This is why, for extending life of pavement and to keep fatigue cracking, low temperature cracking and plastic deformation at minimum level, modified bitumen has been used on heavy traffic roads since 1998. In preparing modified bitumen, generally thermoplastic elastomers (SBS) polymers have been used. It is reality that properties of modified bitumen is dependent on many parameters of which by far the most important are the amount and type of asphaltenes present in the bitumen, and the difference in solubility parameters of the polymer in the maltene phase of the bitumen. In this study, bitumen from Aliaga refinery and SBS polymers have been used to prepare polymer modified bitumen (PmBs), and changes/upgrading of physical and structural properties were investigated. As we know, bitumen characters highly depend on their chemical structure; we examine the physical tests correlating with chemical constitution. This paper presents a laboratory study on various aspects (e.g. compatibility, storage stability, rheology, artificial aging and physical hardening) of PmBs at different polymer content. Therefore this paper describes how physical properties change with increasing polymer content and how it is affected by chemical constitution of the bitumen. Also the results of the physical tests may be used to find out in-situ polymer content of PmBs. After measuring viscosity of modified bitumens, prepared viscosity-polymer content curve can be used to estimate polymer content. For the covering abstract see ITRD E121480.
