THE EFFECT OF AN ORGANOMETALLIC CATALYST ON THE PROPERTIES OF PEN GRADE BITUMENS
Journal Title: Structure and Environment - Year 2018, Vol 0, Issue 4
Abstract
The research objective of the experiments and analyses described in this paper was evaluation of the effect of a specific organometallic catalyst on the properties of 50/70 and 70/100 pen (paving) grade bitumens. The catalyst under analysis is anhydrous iron (III) chloride. It was added to the bitumens at the percentages of 0.5%, 1.0%, 1.5% and 2%. The research included determination of penetration at 25°C, ring and ball softening point test and Fraass breaking point test. The tests were carried out at three states of the tested binder: non-aged, after short-term ageing (RTFOT procedure) and after longterm ageing (PAV procedure). Additionally, viscosity was determined before and after RTFOT ageing. The experimental data were used to determine the penetration index (PI) value and the plasticity range of bitumens. An increase of the bitumen hardness was observed due to organometallic catalyst addition, particularly noticeable after long-term ageing. The catalyst was found to reduce the viscosity of bitumens in the production temperature range
