SALES of aggregates are on the slide, according to the latest survey from the Quarry Products Association.
Results for the third quarter of this year, compared with the same period in 1998, show asphalt down by 11 per cent, crushed rock declining by 8 per cent and sand and gravel down by 1 per cent.
The ready-mixed concrete market shows no change.
Jerry McLaughlin, the association's economist, said: 'It is possible to have overall growth in the industry but lower performance from aggregates.
'About 25 per cent of sales are in the maintenance and new roads sectors, which are in the doldrums.'
