Polymer Modified Bitumen: Review
Chemistry & Chemical Technology, 2016 The main reasons and ways of bitumen modification by polymers were examined. Positive and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic elastomers, reactive polymers, thermoplastics) were analysed. The authors’ achievements concerning modification of bitumen by various polymers, namely indene-coumarone ...

Valorization of phosphogypsum waste as asphaltic bitumen modifier [PDF]
Journal of Hazardous Materials, 2014 The accumulation of phosphogypsum waste from the fertilizer industries, which remain in regulated stacks occupying considerable land resources, is causing significant environment problems worldwide. In that sense, the scientific community is being pressured to find alternative ways for their disposal.
