Morning!
Q1) I need to illustrate the difference between the "traditional" macrotexture offered
by HRA or surface dressing and the "negative" texture
offered by the more freely draining surface types such as SMA and/or proprietary thin surfaces
BUT not illustrating the behaviour of the porous alphalts that have full depth draining
(enrobes drainant?) for which I have already got a slide
Does anyone have a graphic or can scan ( with reference) any diagram that would graphically illustate the
mechanism that leads to these surfaces reducing spray, I already have photographs from Maurice Daines
Report for TRL showing how Porous Asphalt cuts down spray so I don't need to illustate what
it does but HOW IT DOES IT..
Can you point me to a URL FTP site or email the image (with references as required) to me...
Q2) Anyone from Southampton University TRG on this list?......
Regards
John
