I want to pave a pathway in my backyard for rollerblading, etc. It will be about 4 feet by 125 feet. Having it paved by a paving company sounds too expensive (and they aren't interested.) A book I read suggested cold asphalt, said it was much less expensive, easy to do, could be done by a do-it-yourselfer. But I can find no specific info about where to buy, cost, how to do it, etc. Any help will be appreciated!!

My experience with asphalt is very limited, but I'll share what I know.
Cold plant mix is available in bags at building supplies and in bulk form a producer (consult the yellow pages or ask a road worker). The two types of cold plant mix are cut back and emulsion. Liquefied or emulsified asphalt rapid set is another type used in home paving.
Overall installation cost is less than concrete, but asphalt purchased in sacked quantities costs more than a similar quantity of sacked concrete.
Remove grass & sod to firmer soil then compact. Spread and compact a 4" layer of 1/2" crushed rock. Erect edging at the finished elevation. For cold plant mixes prime the base (mist with water for emulsion, liquid asphalt applied to a dry bed for cut back). Spread cold plant mix 1" - 1 1/2" layer and mound in the center. Rake evenly and gently & remove large rocks. Roll cut back until it's smooth. Roll emulsion once wait an hour then roll again (spread coarse sand on top on either for a smoother job). Emulsified asphalt rapid set is sprayed or poured on to a dry bed without priming. After 24 hours, another lighter application then cover with sand and roll.
For rolling use a hand water filled lawn roller or better yet it's cousin a power vibrating type. The latter looks like the former only it has an engine, forward and reverse; one or two speeds, and it does a much better job of compaction. Remember to wet the roller so the asphalt and sand doesn't stick to roller and tear up the surface.
