Hi Albert,

We did a project for LTSA in New Zealand about five years ago which
involved a literature survey on spray suppression.  Unfortunately we do
not have this document in electronic format but we could post you a
paper copy if you would like it.  It is now five years old but may still
be of some use to you.

Please let me know if you would like us to post you a copy.

Regards,

John de Pont

Fellow Members,
It appears the Questionaire did not get transmitted for one reason or
another. I have now included it as part of the email below. Thanks for
your assistance and to those who have replied already thanks, truly
appreciated. Regards  Albert

Dear Fellow Members

I am a senior consultant with Estill and Associates Pty Ltd, Management
Consultants, who have been contracted by the Queensland Department of
Transport Australia on behalf of the National Road Transport Commission
in Australia to research and investigate the application of spray
suppression on heavy vehicles.  It would be very much appreciated if
anyone has any experience or knowledge or information regarding the use
of spray suppression that you contact me with whatever experience or
knowledge you may be able to pass on.  I have attached a short specific
questionnaire which you may like to consider and if possible complete
and return to me by no later than the 6th September.  The project has a
short time frame and I thank you for your early reply.

Look forward to receiving worldwide best practice for the above.
