Because I couldn't believe it, I started a search engine and the first thing I found was Wikipedia, which tells slightly different details. There I found this funny looking picture because there are apparently two cement piles erected. The place has a very cementy feel to it. :-)

I even found some more dazzlingly detailed information and a few historical photos. Wow!! Thanks for the excursion! Let's cite a part of it: (the typo in aggregate is original)

"This group of pavements served as bare concrete through 1950. Main Street was resurfaced in 1960 due to a broken water main. The Court Avenue section is the oldest concrete pavement still in service in the U.S. It has undergone some periodic pavement rehabilitation over the years including 1962, the early 1990s, and 2008.

The pavement was 6 inches thick built in two lifts with hard aggregate so horseshoes wouldn’t wear the pavement. The 4 inch bottom section used 1 part cement to 5 parts gravel with a maximum aggreage size of 1 1/2 inches and a water to cement ratio of 0.60. The top lift was a 2 inch section that combined 3 parts cement with 5 parts sand with a 1/2 inch maximum aggregate size and a water to cement ratio of 0.45. Additionally, quarter inch wide grooves that were a half inch deep were placed to help ensure horses wouldn’t slip. The pavement was also cured using a 2 inch layer of wet sand for a period of 2 weeks. The project cost $2.25 per square yard."

How many parts cement to gravel or sand have you had used in your project? :-)

Years ago I started mixing concrete with two different strengths…….
Strong mix : 1 part Portland, 2 parts sand, and 3 parts gravel
Economy mix : 1 part Portland, 3 parts sand and 5 parts gravel
Then years later I had a friend that managed a concrete company……
He mixed commercially at
One part Portland, 2 to 2 1/2 sand and the same 2 to 2 1/2 gravel a much richer and sandy concrete mix😊
