Black Gold Asphalt (Hot Mix Plant)


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 where fine aggregates 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.

(This is why road repairs/building are done in warmer weather, when temperatures remain stable for long periods.)

Dump trucks deliver the hot mix to specialized pavers that apply the asphalt mixture at a uniform depth, width, slope and temperature, ready for surfacing and sealing by compactors.

Requiring a steady supply of raw materials in bulk (a good paving crew can lay up to 3,000 tons of asphalt in a single shift!), your new hot mix plant will provide plenty of car-loadings on your modern HO Scale railroad.
