What the Bates Road Proved About Highway Paving

The story of the Bates Experimental Road, built by the highway authorities of Illinois, is one it will pay every taxpayer to know.

For the better part of two years fleets of loaded motor trucks passed over this road, transporting a total of more than 1,609,000 tons. Only thirteen of the original sixty-three section of this two mile stretch survived. Ten were of portland cement concrete.

The other three had heavy concrete foundations which in all respects corresponded to the plain sections of portland cement concrete.

Many other sections with wearing surfaces placed on less enduring foundations were failures, proving that the foundation strength of concrete was the winning factor.

Many communities are profiting from the lessons taught by the Bates Experimental Road.

Is your community one of these? If not, why not?

Tell your local authorities you want your roads and streets paved with portland cement concrete. That will end once and for all the problem of costly maintenance.
