LABORATORY STUDY OF AND TEST ROAD EXPERIMENTS ON INCINERATOR RESIDUE AT SYSAV, MALMOE

UNDERSOEKNING AV FOERBRAENNINGSREST FRAAN SYSAV, MALMOE, GENOM LABORATORIE- OCH PROVVAEGSFOERSOEK

Incinerator residue is not normally used in Sweden as a road material. However in autumn 1982 material from the Sysav plant in Malmoe was laid as a sub-base aggregate in flexible pavement test sections in the harbour area and incinerator plant area of Sysav, both carrying heavy commercial traffic. Alligator cracking occurred but control sections with a sand sub-base remained in sound condition. The residue was subjected to laboratory tests and showed a very high CBR value but a low resilient modulus value. An attempt was then made to stabilize the material with portland cement but a rather high binder content (greater than 10%) was needed. An on-site investigation of the failed areas was carried out during 1983/1984 both by falling weight deflectometer measurements and by excavating test trenches. The falling weight deflectometer measurements showed a tendency to lower modulus values for the incinerator residue than for sand sub-base, while the moisture content in the residue was found to be considerably higher than the optimum requirement. These results confirmed the findings of a literature survey which revealed that, while incinerator residue is often used in roads in other countries (albeit low volume ones), the material must be conditioned a certain time before use and compacted near the optimum water content, otherwise bearing capacity can be reduced.
