DOMESTIC REFUSE MAY BE GOOD FOR DRIVING ON

This article gives a brief account of trials using incinerated domestic refuse in road surfacings in the US and as road fill in the UK. A 5-year pilot programme by the Federal Highway Agency (FHA) has resulted in pilot schemes in Houston, Harrisburgh, Philidelphia and Washington. The refuse used has been heated to 1500 degrees C and is used with crushed rock in asphalic concrete. Results are reported to be promising and FHA may encourage more of the 150 US cities with incinerators to adopt the process. In all they are producing 5 million tonnes of residue a year. The Transport and Road Research Laboratory have been studying the utilization of the 1 million tonnes of incinerated refuse being produced each year by the UK's 30 incinerators. Residues from Edmonton, Nottingham, Derby, Birmingham and Sunderland have been tested. The ash was found to vary in properties and it was concluded that the refuse would be unsuitable for use as a sub-base beneath a concrete pavement, but would be acceptable beneath a bituminous roadbase. Apart from needing to be well burnt the residues should be kept low in metals, since iron residues oxidise with a doubling in volume and leave holes when the disintegrated material is washed away. Residues with as little as 5 per cent magnetic material, such as those from Edmonton would be unlikely to cause any problems. /TRRL/
