Further tests on single-drum rollers have been recommended by the
working party of the Highway Authorities and Utilities Committee
(HAUC) to gauge their suitability for meeting its reinstatement
compaction specification.
According to HAUC working party chairman Alan Rainford, a statement
will shortly be published on its website outlining the completed
test results. It will state that single-drum rollers have achieved
the required compaction levels.
However, he said further tests are needed to iron out a few doubts
and make sure everything is 100% satisfactory.
"Manufacturers have been informed," Rainford said. "But the tests
won't happen until funding has been sorted out."
The original tests were supervised by the Transport Research
Laboratory. They were seen as a temporary stay of execution for the
machines to stop them from being outlawed from road reinstatements.
Funding for further testing is not secured, as the two main
manufacturers, Terex and Bomag, which jointly provided £40,000
for the original tests, are unwilling to pay any more.
A spokesman for Terex said: "We've already paid for tests that have
proven our rollers meet the required standard. There's no way we
will be funding more tests."
The manufacturers would like a statement from HAUC as quickly as
possible, making it clear that single-drum rollers have met the
compaction specification.
"The longer HAUC delays, the more money we lose through customers
not buying our kit. We just want it clarified," the Terex spokesman
said.
"We won't be paying for more trials, it's a waste of time," said
Alan Batty, general manager of Bomag GB. "We just want HAUC to make
a clear statement; it's already months overdue."
