Did You Know?
In 1783, inventor John Loudon McAdam returned to his native Scotland after amassing a fortune in New York City. He became the road trustee for his district and quickly set his inventiveness to remedying the terrible condition of local roads. After numerous experiments, he created a new road surfacing material made of bits of stone that became compressed into a solid mass as traffic passed over them. His invention revolutionized road construction and transportation, and engineers and the public alike honored him by using his name (re-spelled macadam) as a generic term for the material or pavement made from it. He is further immortalized in the verb macadamize, which names the process of installing macadam on a road.
My Take
Macadam, hey, a word I not only know, but I know well. In fact, I use it everyday life. Just two months ago, I had my driveway serviced with a top coat of macadam. It looks great, and it will sustain my home for decades to come. Some people call it asphalt paving, but that is not entirely accurate.
“Asphalt pavement comprises stone (aggregate), sand, additives and liquid (petroleum) asphalt. Liquid asphalt—a black sticky substance—is used as the binding material in asphalt pavements. It is viscous in nature and also in semi-solid forms. Another common term for asphalt is bitumen. The pavement—once mixed—consists of 90 to 95% aggregate and sand, and 5 to 10% asphalt or bitumen.”

Since macadam is only 5 to 10% bitumen, macadam is a more accurate name for the substance.
What I don’t care for are the potholes that frequently occur during the freezing / warming seasons. If macadam has even the smallest void, water can seep into the macadam. During freezing cycles, the water expands and forces the aggregate to disengage from the roadway, allowing more water to flow into the void. As the ice melts, the disengaged aggregate washes away. The result is a hole that grows into what we call potholes. Potholes are the bane of our cars, from minor tire damage to broken axles. Something that I am sure every driver knows. I’m not saying anything you don’t already know. Of that, I am certain.

Others could ask why these six people had appeared together. Watching the group, I can see why. Twenty years in age separate the youngest to the eldest. They come from all walks of life. They consist of nerds and extraverts, techies and non-techies. There’s a renaissance man, a secular politician, a project manager, a software engineer, a contractor, and finally but not least, a therapist. They are smart, street smart, worldly and sheltered. Frankly, something I don’t understand, is how, why and under what circumstances these unlikely of people could gather together and share their precious time together?
well the list goes on and on. Take, for example, television and movies. In short order, the group touched on ‘Galaxy Quest’ as a spoof of ‘Star Trek,’ ‘Dr. Who,’ ‘Guardians of the Galaxy,’ ‘The Hitchhikers Guide to the Galaxy,’ ‘Humans,’ ‘Brain Dead,’ ‘Designated Survivor,’ ‘MacGyver,’ and a plethora of others. Travel and vacations turned to ‘Disney World,’ and Hawaii. Food included the best recommendations from the menu, including ‘Cannolis,’ and Steak Bombers, thin-crust pizza vs. thick-crust, and the excellent fish fry. For three-plus hours, this unlikely group shared themselves with each other.
