gravel rolled into asphalt
(OP)
Hi,
I am wondering if it is possible to have gravel rolled into the surface of asphalt as its being installed. The purpose is simply for aesthetic reasons. I don't really like the look of a solid black driveway. I've looked into getting tar and chip, but, there are very few people who do that in my area. In fact, the only company I found that does, only installs it on an already paved surface. So, being its late in the season, I decided I'd get the asphalt driveway installed, and then could alaways at a later date, put down the chip seal.
One of the contractors I spoke with about the asphalt driveway, suggested rolling gravel into the surface of the asphalt immediately after it has been rolled out. Is this ever done? Does anyone have an opinion on this from both a structural and aesthetic standpoint? I'm thinking it may look like exposed aggregate surfaces in concrete. But, would the aggregate really get into the asphalt and stick without that layer of tar? And, if this is an ok thing to do, would it work better with one type of asphalt mix over another (fine surface layer vs a binder course)?

Have you considered StreetPrint or it's competitors? It's not the exposed aggregate surface you're talking about, but it isn't plain asphalt, either.

Yeah, I thought it would wash off, too. It only lasted thirty years.

Mike Halloran: About the cement dusting, I wonder if you could post, or send me a picture of this. Is it a solid layer of cement, or just a light dusting that gives the appearance of a wash? Does it look like cement, or more gray, like weathered asphalt? And, what is the final color? Did you do this on top of the brand new asphalt while it was still tacky?
And, about the gravel compacted into asphalt. Is this usually done on the typical densely graded 1/4 inch wearing course or a more open graded asphalt? How small should the chip be? Francesca: do you know what the red chip is that is used on London streets? Its a very intriguing technique. The addition of some colored aggregate would add alot of visual texture to an asphalt driveway.
