In the near future I plan on preparing a display base that will include some paving...some concrete, some asphalt.  I had heard of several methods on producing scale concrete, but figured I try them all for comparison sake and to have swatches for future reference.

http://photobucket.com/albums/y144/qclex/pavements/

I've used 5 materials:
Fine Ballast: by woodland scenics (look for it in railroad area in hobby store)
Gold Bond:  was looking for plain talc powder (which comprises the majority of GB) but guess ev'thing has a brand name now (look for it at the grocery store)
Baking Soda (found at grocery)
Stucco: a matte medium produced by liquidtex that has small bits of sand in it thus mimicking stucco once dried (look for it at michael's)
Corn Starch (also at grocery)

Each swatch is typical styrene brushed over with liquidtex acyrlic medium matte.  Then a ample amount of the testing material thown on top and allowed to dry overnight.  A soft brush was used to remove all un-attached material and swatches were shaken and tapped for any loose material.  A small area of each swatch was then masked off and lightly sanded with 200 grit sandpaper, thus making a slightly smoother texture.  This 200 sanding shows on some of the rogher textures but doesn't on others.

Each swatch was painted with tamiya sky grey and given a misting of Testors Dullcote.

Results.

I was pleased that each gave a different texture, and believe all have uses in some scale or use.  

The items shown adjacent each swatch are a US dime and a small figure and military vehicle in HO (1:87 ) scale.  

I'd like to hear of others experiences with these materials and/or other methods and materials to reproduce scale paving.

Very cool. I'm digging both the stucco and baking soda. The others (adise from the ballast) are hard to see probably due to the smoothness. The ballast looks rough but would look great for a gravel driveway with a little lighter gray or white drybrushing.

I really like these swatches that you've been doing. A great way to see what looks like what to compare.

yeah...baking soda and stucco are my faves too.
both are nice...random.
i'm say...for something like 1/100, the stucco (sanded) makes a nice porous asphalt...and the baking soda a nice concrete.  if looking for a mirror smooth concrete surface...i may recommend the gold bond.  the pix for the c'starch may not show well...but it does have some variations....is so thin it almost picks up the brush strokes of the matte medium below.
the stucco and baking soda are nice..you can really see their texture...but feel, for true scale, they aren't appropriate until you get up into 1/72 scale.  just my 2 cents.  think of when you walk on smooth concrete (not a broom finish sidewalk). with your eyes just on your shoulders its hard to see lots of texture....now look at the size of the shoe on the figure in the pics for a little reference.  but sometimes, like on stage, its good to exaggerate a emotion, a look, a texture just for dramatic's sake, no?  to each their own

the ballast is a neat product...but fairly big for our typical scale.  i tried to put it in a blender to make it smaller...but didn't quite work.  gravel is the right idea.  perhaps mixed with some thinned out white glue into a slurry, it might make a nice asphalt for something in the 1/20 scale **wink** ,perhaps?

I used ballast for my Neighborhood Watch base rubble dust and crumblies. I ended crushing it to be finer in a makeshift mortar and pestol. A screwdriver handle end and a round PVC end cap. (4") So maybe the crushed would work... I'll have to try it.
