As America’s infrastructure is continually described as “crumbling,” I thought it would be a good time to take a look back to how highways were paved around 70 years ago. A lot has changed in the past seven decades, but you might be surprised by how similar paving still is.
In the video below, uploaded to YouTube by “US Auto Industry” and titled “Building a Highway (1948),” you’ll see the complete steps to paving a US highway with concrete. Depending on your geographic location, concrete may or may not be more prevalent on your local highways than asphalt.
The general process of building a highway hasn’t changed very much over the past 70 years. It all starts with surveying, then rough grading, followed by finish grading, and pavement. The machines look generally the same, albeit they’re in color now and also vastly more complicated with electronics and other technologies built in.
This is also only one example of a highway in the 40s, but the biggest differences that were evident were the lack of a stone base underneath the pavement, smaller gauge steel reinforcement, and much greater on-site material mixing.

As you may already know, the NBA’s Milwaukee Bucks officially opened their new home, the Fiserv Forum, for the 2018-2019 NBA season last October. That new stadium is being heralded as the “World’s First Bird Friendly Arena,” due to many of the design features. Well, since the new one is open, we can only expect that the old, non-bird friendly (I’m assuming) arena has overstayed its welcome and has to go.
Two and a half years ago, I came across one of the most interesting construction projects I’ve ever seen, called The Guedelon Castle. In a world with cordless power tools, smartphones, and tables strewn across the jobsite, the Guedlon Castle is being constructed solely from 13th Century building techniques in Burgundy, France.
Let’s get 2019 started with the first building demolition by implosion of the year.
The Smithsonian channel is airing a series of shows titled America in Color, in which they enhance lost or forgotten video footage of the 1900s, beginning with the 1920s. Part of the first episode in the series shows the men that worked on skyscrapers in New York City and it’s been edited to show color, as opposed to black and white, for the first time.
Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
Look, you could mobilize on site the boring old way by loading your heavy equipment on the bed of a trailer and driving it to site, or you could take a note from the Bravo Company of the 37th Engineer Battalion of the United States and spice things up a bit.
A couple of years ago, we shared a video of Fastbrick Robotic’s Hadrian 105, a brick-laying robot built for proof of concept. In a true testament of how long the development of computer-model based commercial robotics takes to develop, the company’s commercial robot model, the Hadrian X, has finally reached a goal that has been sought after since 2015: Building a 3-bedroom, 2-bath home in 3 days.
