I was at a large building show last week and some of the most active booths were hard surfaces that drain. Since all of the vendors had running water displays the booths were crowded and I did not get a chance to ask any question, so here goes:

1. With the draining asphalt, why would you use it?

2. Does it ever clog?

3. If it gets clogged what can you do?

4. Since it drains so quick, does it require a ton of draining (stone?) under it or do you use a pvc drain system?

5. Any issues with it freezing in the winter and blowing apart?

There were also a bunch of walkway systems that drained on display, some looked like pea stone. I'm not sure if the attraction was the running water and cool it was that these "hard surfaces" could drain water or if people actually had a use for these products. For some reason the light bulb is not going off in my head as to why these are great or even needed products.

Bump.

Why are so many people selling this stuff if we the people that would install it know nothing about it?

Note: we= not me, but the members here that pave or do landscaping as a business.

The first thing that comes to mind
is to reduce or at least slow and
divert run-off.
Controling run-off is more and more
important to reduce the load on storm
sewers and help with flood control in
developing areas.
Might save or reduce the necessity
of a retention pond in some cases.

The asphalt you are referring to is a new type of asphalt that will be able to be applied to clean stone instead of ABC(crush run) The asphalt is more or less still in a do and learn phase. Mostly the idea is just to keep the correct slope patterns of your sub grade to help divert water to ditches, catch basins or what have you. Hope this helps!

There seams to be a bunch of hoopla around this stuff I have heard of both pervious concrete and now tar. The problem they are having with the stuff is silt or road grime clogging the surface.. France experimented with the pervious tar about 12 years ago on a major highway to combat hydroplaning. I am leary, I think its more marketing than anything. If the water is under the tar or concrete or in it for that matter and it is subject to freezing it sounds like problems.

My super was playing around on the internet and between porn sites he came across a site that had that self draining pavement on it.

He showed it to me and the first things I thought were 1) how does it drain after a little silt / sand gets on it and 2) how does it drain when it gets some frozen water on top.

I'm sure its good when its new. In fact the demo footage on the web site was rather impressive, but with out any information on the above formentioned dynamics, I cant imagine it would work long term.

Some years back when we had a little choice in who we bought asphalt from, the smaller more client friendly plant would actualy make such a mix if I told the plant manger I wanted a mix that would self drain because a given area has a slow pitch. And it always worked..... At least for enough time to get paid. I couldnt say if it lasted but in looking back, we never got any call backs for those jobs.
