Interstate 30 in Texas, 10 miles east of Dallas. Another highway of new-type concrete.
SUCH PERMANENT QUIET.. . EXTRA COOLNESS, TOO, ARE BUILT INTO EVERY MILE OF NEW-TYPE CONCRETE!
(No pavement could be stronger even if carved from solid rock)
The happy miles whirl away smoothly under your wheels! You listen, but there's not a "thump" to hear or feel. This is new-type concrete. It's sound conditioned . . . laid continuously, with only narrow sawed-in cushion slits.
Life's easier for your tires, too. New-type concrete is flat-no waves and dips. Your tires do less flexing. Less flexing means less heat. Less heat - longer tire life. These benefits, like all the others you get with concrete, are lasting ones. New-type concrete is solid man-made rock that actually grows stronger with age. Adding to its "muscle" are specially designed subbases.
Even freezing and de-icing chemicals can't roughen new-type concrete. Billions of pinpoint bubbles put into it by "air entrainment" give built-in weather- proofing. There's built-in safety, too, with concrete's quick-stop grainy surface and its light color for better nighttime visibility.
As a taxpayer, consider this: only new-type concrete enables engineers to design highways expected to last 50 years and more-with maintenance costs as much as 60% lower than for asphalt. The moderate first cost isn't just a down payment! You can see why new-type concrete is preferred for the Interstate System.

Newest Interstate System route to be completed in concrete. Interstate 83 . . . 70 miles of 4-lane highway connecting Harrisburg, Pa. and Baltimore, Md. Thousands of miles of new-type concrete are already in use on vital sections of other Interstate routes now being completed.
