That looks rougher than the chip seal I rode on in West Texas, but not by much.

I was on a week long van supported tour, all we had to carry on our bikes each day was our water and lunch, van hauled the camping gear.

I had my folding bike with 40mm wide Marathon tires. First day between 75 and 80 psi in rear, between 55 and 60 in front. My hands really took a beating from that rough chip seal, my GPS was not happy either and my GPS still has occasional problems from that day of vibration. Day two, kept my rear tire at the same pressure but dropped my front tire to between 40 and 45 psi, my hands and GPS were much happier. And that was enough pressure in a 40mm wide tire to prevent pinch flats. If it slowed me down any, I did not notice as the other riders that were slower than me were still slower than me.

Pavement like that is one reason that the narrowest tires I tour on are 37mm if on a 700c bike and 40mm if on a 26 inch bike.

Photo is some of the chip seal on the road into the Florida Everglades, and one of the road hazards.
