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.

Every construction site has its own unique set of challenges, but mix in extreme cold and a remote location and things can get pretty serious pretty quickly. Construction documentary maker, The B1M, recently created a video of one such site, dubbing it “The World’s Most Extreme Construction Site.”
Infrastructure projects can require some pretty massive heavy equipment to perform all necessary tasks, so it’s a great opportunity to get some stunning footage of the machines and workers during the process.
A few months ago, we wrote about a pretty weird and creepy robot dog that was designed to navigate tough and constantly changing terrain, such as on a construction site. Boston Dynamics, the maker of robot, has now officially announced it is available for sale.
The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
Late last year, crane manufacturer, Sarens, announced that their brand new – and enormous – crane, was ready to be sent off to it’s first job. After several months of prep, the Sarens SGC-250 has finally made it onto its intended jobsite and is ready to lift.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
Unless you work on infrastructure and some other specialty structures, you’ve probably always wondered how underwater structures are built. It’s always admittedly been a bit of a mystery to me, as I only encounter relatively small amounts of water on my retail construction sites. Some dewatering here and there or a small creek relocation can add some difficulty to a project, but they’re manageable.
As large of an industry as the construction industry is and with the amount of characters that I’ve met in my career, I’ve always been surprised at the lack of television programming covering large building projects. The Construction Channel, an online new media company, is taking matters into their own hands and has recently released episodes of a documentary series called “Six Figures, No Suits” (SFNS)
We have featured Priestly Demolition Inc. (PDI) on Construction Junkie many times, because of one simple fact: they produce high quality and informative videos about their craft. That’s not something many other companies in the construction industry can say – and now it’s paid off for them in the form of a television show.
