RECYCLING OF WASTE OIL DISTILLATION BOTTOMS IN ASPHALT

A field trial of hot mix asphalt using distillation residues was undertaken to investigate the potential as bitumen extenders for use of the vacuum distillation residues (called "waste oil distillation bottoms" or WODB), produced during the re-refining of waste lubricating oils. The construction of the field trial is described. Three sections of hot mix asphalt pavement were laid at a site on a roundabout in Hamilton, New Zealand, in May 1991. The trial consisted of hot mix asphalt manufactured using 80/100 grade bitumen on a control section, and using blends of 180/200 bitumen with 9 percent and 20 percent of WODB respectively, air-blown to a nominal 80/100 grade penetration, on two sections. The physical properties of the mixers were monitored at 14 months (1.3 years) and after 57 months (4.7 years). The WODB-blended mixes did not show greater levels of surface deterioration, cracking or rutting compared to the control. The WODB were known to contain lead (from petrol additives) and metals from engine wear. After 57 months, analysis of lead, chromium and zinc contents of the hot mix asphalt in the trial sections showed that up to 25 percent of the zinc had been lost, while lead and chromium levels were similar (95 percent confidence level) to those initially present in the asphalt.
