MODIFICATION OF BITUMINOUS BINDERS WITH POLYMERS

MODIFIZIERUNG BITUMINOESER BINDEMITTEL MIT POLYMEEN

Because of their favourable viscoelastic properties polymers are best used for improving the rheological behaviour of bituminous binders. The modification produces a reduction of the penetration, improvement of temperature sensitivity and also a raising of the softening point, the penetration index and the viscosity. Moreover the admixture of polymers and in particular of elastomers, serves also to improve the mechanical properties such as the impact resistance at low temperatures and the elastic recovery of bituminous mixtures. To achieve the required rheological characteristics, preliminary tests tailored to the particular application of the system bitumen/polymer are essential. /TRRL/
