Edward J de Smedt Patented Asphalt Pavement – May 31, 1870
On May 31, 1870 Belgian immigrant Edward J de Smedt who was at Columbia University in New York City patented asphalt pavement. So we all know what asphalt is, as we all drive on it, and have all felt that heat rising off of it in the summer! But do you know how it is made? I didn’t until I started to deal with it at my job.
