Walthers Cornerstone Series®

 HO Scale 

By the late 1990s, some 93% (about 3 1/2 million miles) of American highways were built with asphalt. The paving work starts at hot mix plants, like Black Gold, where fine aggregates (sand or gravel) are mixed with a binder made from bituminous, an oil by-product. This mixture is heated to 250° to 375° Fahrenheit; too hot and structurally weakening carbon particles form, too cold and it won't compact correctly.

Requiring a steady supply of raw materials in bulk, your new hot mix plant will provide plenty of car-loadings on your modern layout.
