Model highways. What works- what doesn't. Best ideas
Posted by Split Reduction on Saturday, March 27, 2010 11:14 PM

I have been building highways and roadways using old 1/4 inch panelling cut with a jig saw to the width and curvature needed. Over this base I have been applying Woodland scenics paving material. I also use "sculptamold" for a roaway base, but it really is a bear to sand smooth after it sets.

I'm curious to learn what others have found to be a successful way to create model highways and roadways.  We drive on these roadway every day but I seldom see "realistic" roads modeled in the usual publications...

Sculptamold hard to sand smooth?  You must be using the alternative, high tensile strength product.

I make roads using sculptamold.  I mix it to about he consistancy of oatmeal, and scrape it mostly smooth with an artists palette knife after I lay it, making sure there are no large dents or bumps in the material..  When it's try, a few passes with a standard sanding block and 200 grit sandpaper smooth it out nicely.  I color it with a mix of Grimy Black and Dark Gull Gray washes.

I have used the adhesive-backed, flexible foam road surfaces available from Noch and others, but I am not happy with the results.  They look too uniform and well maintained for NE roads, the lines are the wrong color, the adhesive comes up after a couple of months, and it's impossible to hide seams / joints.

 In Oct. 2007 MR, IIRC, there was a feature on a layout of a guy, using asphalt shingles for his roads. I use 2 mm Styrofoam sheetstock for all type of roads, from tarmac, concrete all the way to cobblestones. Just need a lot of patience to do that. Coloring is done with washes of India ink. Light washes for concrete roads, darker washes for aspahalt roads and cobblestones.

If memory serves there was a good thread on a similar approach recently here in the forum: http://cs.trains.com/trccs/forums/p/169861/1864501.aspx#1864501.

Also shingles mentioned in: http://cs.trains.com/trccs/forums/p/104516/1242655.aspx#1242655 which has lot's of other suggestions for materials.

 To OP
Once you decide on an approach, you might want to look that the follow set of photographs.  Excellent hi-resolution photos of details on construction of a (real) asphalt road with drainage ditches: http://www.gettysburgdaily.com/?p=282

I use Durham's Water Putty.  The trick is to add a bit of vinegar to slow setting, and to use a wet foam brush to keep smoothing it down as it's setting.

I prefer to use Hydrocal plaster, rather than Sculptmold, for roadways. Sculptmold is best for "sculpting " mountains. For areas where there is extreme "hands on" , I use Cement filler from a can. Hydrocal is extremely hard and water proof, so I use it for water proofing the bottom of rivers. It does require priming, in order to paint it. Bob Hahn

I use premixed drywall compound. It doesn't need sanding. I get it as smooth as I can when I apply it then when it's dry, wiping it with a wet sponge softens the surface and I can get it very smooth with the sponge. I use an offset spatula like an artist's spatula or cake decorating spatula to apply the compound. That tool makes it much easier to work on a horizontal surface with than a straight spatula.

 I went through several methods before settling on a variation of this:

http://www.telusplanet.net/public/crowley/ashphalt_roads.htm

 The foam he used is irrelevant as any craft type foam 2mm thick will work.  I get mine from hobby lobby for 0.79 for a 12x18 sheet.  I use smooth it as the plaster.  Tried hydrocal and others but smooth it brushes on the foam and levels out better.  You want the smooth it mix just thick enough to stay on the foam well but not as thick as the instructions say.  I probably use about 25% more water than the instructions on the box call for.  I mix in black paint to tone down the plaster color which can be the perfect color for cement before touch up and weathering and gives a good base to paint it for asphalt.  I vary the paint I use and the weathering to make it more real world.  Newer asphalt is darker than old and the mixes can vary a great deal in color.  I even add pot holes and patch areas which I do by painting darker.

You have got to be kidding! 

I use the same method. It works fantastic. From now on I won't use any other way. Its fast, and very simple to do. The 2mm foam is cheap at 79 cents a sheet at hobby lobby. Simply cut it out to fit your road dimensions.I use the grey road foam so that when I sand it the grey comes through and looks like road wear. The drywall compound can be colored and used over and over again. I have 2 containers. One asphalt and one grey color.

There's a website somewhere that shows exactly how this works, but I can't seem to find it.

 I think I originally found it on here or one of the other RR forums.  It's funny how the results turn out like they do, I wasn't sure as I had tried other methods with so so results.  I like how the foam keeps the road smooth but allows the road to move with the natural shape of the terrain as well.    Plus it's so easy to but your roads right up to the track for crossings.  Styrene didn't allow this and straight plaster was always a pain to get smooth.

 What do you use to glue the foam down?

 I personally have been most pleased with the web spray adhesive such as scenic express sells. You just need to let it sit for about 5-10 minutes before placing the foam on the layout because if you put it down right away, the gases from the adhesive curing process in the beginning will cause the foam to bubble up.

I may try the drywall mud as well.  How watery do you mix it to get good results?

Glad to see someone else using this method with good results!

I use plain old yellow carpenter glue.Or white Sobo craft glue.

Pancake batter. I'll also use drywall quick plaster and mix some black/grey and use it as a cement ramp for the grade crossings. A little sanding and it looks great. (I still need to sand the ramp up to the crossing)

Here's a few pics....

 I like to use good old fashion tar paper. Its very easy to cut. I carve in cracks, and depending on what type of road I am doing,I can dig out enough for pot-holes or add cobbel stone here and there & maybe a manhole cover, and spray it with dull coat, and weather it with light gray chalk. I don't know how to post pictures yet.,but as soon as my son shows me how. I will post a lot of pictures.    Sam

 In the past I have used roofing felt with great success. I find asphalt roof shingles way too heavy for HO may work for G or O gage though. I am planning a stretch of concrete road and I visited a layout where the builder used bass wood and real cement dust over a bed of white glue. I have seen bass wood just sanded and painted with a concrete color. I've seen Howard Zane do them on a .020 piece of shirt cardboard also.

Just my 2 cents worth, I spent the rest on trains. If you choked a Smurf what color would he turn?

 I wonder if anyone else has used photographs from the computer for road surfaces and markings.  Her is an example:

 

 

Some of the surfaces are vinyl spackle painted with Woodland Scenics black and marked with Chartpak tape.

 Why not incorporate several road making systems into your layout?

 First off it would give you some idea on how each worked for future reference, but more importantly it would give your roadways different looks.

Quite often you'll find one road making system employed per layout and consequently the roads all end up looking alike.  Travel around your area, does all the pavement look alike?  I know in my area it doesn't.  Different colors, different textures, different degrees of "crown" (with some roads not having any at all). 

 Styrene, foam covered with plaster, the Woodland Scenic's road making system and even this one, the Real Road System, merits a look see. 

Use some different ones on your layout, finish them off with different colors... I think the contrast between roads will end up making each one that much more unique.

 Maybe it's just me but the "real road system" seems a little expensive for 12' of HO two lane.  Most other methods you can make 12' of two lane for 1/8 to 1/3 the price.  It looks to me like someone has come up with their own method for road making and is trying to sell it at a rather large mark up.  It's just too simplistic and doesn't offer anything spectacular for me to spend money on.

 Yeah, I agree that it's pricier... And once could certainly use the other methods to create some different looking looking roads.

 However in the grand scheme of things I don't view dropping $20 for 12' of HO road as being a budget buster... Not with the amount I have tied up in engines and rolling stock if you know what I mean. Smile,Wink, & Grin

 And it will create a different type of road as compared to the others already discussed... Again, it's the ultimate contrast in road look and texture that will make all the roads on layout "pop".   Too often we see layouts where all the roads look the same.  

 I think one can find lots of products out there that have a high markup from the manufacturing point to the retail point... It's just how this stuff works.  The pair of blue-jeans I pick up at JC Penney's for $25 probably don't cost a 1/10th of that amount at the manufacturing level... But I still buy'em.

Instead of using "Sculptmold", I would suggest that you use Hydrocal plaster, (if you must use anything?) I like to use Hydrocal plaster for waterproofing the bottom of streams and harbors. It is extremely hard and smooth. I don't bother with styrene, for the road surface. The Hydrocal must be primed, before being painted. Bob Hahn

 I get what your saying Michael but there is more principal there for me.

 To me it's kind of like the guy who I linked that shared his foam method not sharing the method but instead packaging the products then reselling it for 8 times it's cost.  Kind of lame.  To me the line kit is even more of a joke, paint markers and some masking tape it seems to be.

 As far as the patented material part I don't doubt the paste is patented but highly doubt the seller of the system holds the patent.  I really can't see a return on investment for patenting a model rr road system that has very limited marketability.

I have big $$$ tied up in locos myself, but they are the center point of my model  rr and not a side feature.  No one looks at my layout and says "oh what nice roads you have" yet they all comment on the locos, especially when the "strange looking" BLI AC5 comes around puffing smoke and making noise.  I can get just as good if not better results than that road system at a much cheaper price.

 That's one of those things that you don't know unless you try.

 Hey, for $20 I'm willing to take a chance. Wink

 And again, I'm going for contrast in my roads.

Kurt, a master modeler from Germany, is currently modeling his version of Lance Mindheim's "East Rail" Miami Layout.  Kurt is using 320 grit sand paper that is put down with 3M Super 77 adhesive and then a beige wash is applied.  Whatever you use, it is worth it to check out his work on the Gauge Forum.

 Hydrocal is easy to shape but hard to sand.  It can be planed with a carpenter's plane, which might not be good for the plane, but a layer of vinyl spackle from Dap or Crawford's spackling paste - both sold at Sherwin-Williams stores but, perhaps, not at the same time - can be sanded easily.  A concave sanding block can be fashioned to put a crown on a road surface of vinyl spackle.

  That works if you like very obvious seams in asphalt.

The Real Road system, while "pricey" seems a lot easier to work with than some of the suggests in this thread.  One trades time for material in modeling.  Remember the key feature is the ability to create the road OFF of the layout.

 The seams can be colored.  Unfortunately, the road systems in this country are a patchwork of patches.  I have used this method with success.  It does provide a textured surface that is nice. True continous beautiful asphalt exists only in model railroading.  LOL

Personally, for city streets, I prefer the sheet plastic using the method as described by Lance Mindheim and that is only affordable if you have access to .060 4' x 4' styrene or larger sheets.

I have been using a product that I got at Home Depot called Patch-N-Paint (the lightweight formula - $6.48/32 oz).  It's a spackling compound and if you can spread butter on toast, you can do this. It has the consistancy of whipped butter.  Easy to sand and feather edges to make an old country road or a downtown main street.  Takes paint well.  I got the samply size cans of Olympic at Home Depot (7.12 oz for ~ $3) and they paint a lot of road.

In the past I used plaster mixed with fine ballast and dark grey paint.  A key advantage of that was I didn't have to worry about white spots due to chipping.  When it dried I weathered the surface.  Spreading it evenly and smoothly can be a challenge.  I would say this method works well to represent an old, uneven, beat-up asphalt road with crumbling edges (potholes and rough spots sometimes just happen for you as you're spreading the material) and you can actually make patches and fill potholes with a darker, smoother batch of the same material.  Change the color a bit and maybe go with slightly larger ballast and I would think this would also give you a very convincing old-style rural "oiled" road (a gravel road with a thick, sticky brownish goo poured on and compacted to form a sort of pavement).  But as the earlier poster noted, not all roads are the same.  You would want to use a different method for newer, fresher asphalt, and probably yet another method for concrete, especially those old concrete highways with regular expansion cracks every few yards (they were like a giant sidewalk, as I recall).  I will probably use two or three different methods on my new layout.
