The Subject line pretty much say's it all, NOT TODAY!
At least 95F outside window all afternoon.
No painting, no laying resin, no drinking beer. WHAT?
No drinking beer?
Even a cold one doesn't
taste good on a day like this.
Time to stick with water and stay in the shade.

If you didn't use a level, what would you use?
As a commercial superintendent, I have literally been responsible for acres
or concrete and pavement. I can crown a road or drive with a 4' level, a
sighted level or a water level.
Standard drainage declination is 1/4" per foot (no snow consideration), les
s or more if stamped by civil engineer.
Say you wanted to put a crown on the road to make it drain to the gutters o
n each side that drain into a runoff drain box or to a collection point on
your street. Start at the drain lip, and using something as simple as a 4'
level, drive a peg (we use rebar scraps) until it is 1" higher than level.
Now you have proper drainage. Repeat from the top of your peg to establi
sh another 4'. To get the standard 10' lane, from the top of your last peg
go another 2', then raise it 1/2". Now you have one half of a two lane st
reet, with the proper drainage established.
When you pour concrete, you pour to the top of the pegs, using your straigh
t edge from peg to peg to keep it crowned. When you are laying asphalt, yo
u are laying it over graded material that was laid, cut and compacted to gr

For road work, parking lots, and other large areas, you simply use a sighte

Let your mind wander. You can change the angles to anything you want, you
can start at the high point and go down instead of up, you can make a wide,
single slope road or drive, etc. To make the curves more gentle, simply m

When we are doing paved walks, small patios, or anything else small we just

zip tied to a 10' straightedge, and establishes his grades in short order
once he figures out the math.
Not sexy, but you honestly sounded like you didn't know.

Agree, that was interesting to know.
Are things done differently for very wide roads? I have in
mind some parts of I-95 in FLA and GA that are 4 and 5 lanes
wide on each side, and seem to be darn close to perfectly
flat. They certainly don't drain worth a darn when it rains.
Is there some limit on how low the edges can be, that prevents
cambering very wide roads?

Wider roads become problematic due to existing drainage conditions. Factor

And yes, depending on its design a wide set of lanes can have a nice camber
to it, and unless severe you won't notice it in your car. Around here, fo
r off ramps and entry ramps that are 2-3 lanes wide, they use a single slop
e draining into a system that handles only that ramp, and dumps somewhere e
lse. No camber, only slope.
Basically today the setup is the same to establish road beds. In the old d
ays, angles were "turned" (coined by turning the head of the instrument to
the correct angles to determine a curve. Now they use a theodolite, which
does the same thing with incredible accuracy. They still use sighted level
s in some cases, but also use lasers for long distances.
Most $400 levels will shoot a level line about 150' or so with no more than
1/4" deviation. Lasers will go farther and are more accurate (and much, m
uch more expensive) but you don't have to deal with heat shimmers or trying
to read the measuring rod. When I was setting forms and leveling tilt pan
els, we used to take a reading in the morning, move the instrument around n
oon and reshoot, then move closer to the work and shoot one more time at th
e end of the day.
Really, it was fascinating for me to learn that stuff, although today I use
an inexpensive level and the largest thing I have shot in lately was a fri
Speaking of level, one of the mysteries of modern life is
why modern day road paving technology is unable to get a
manhole level with the road.
When I was young, pretty much all the manholes were flush
with the road (when you ride a bicycle, you're pretty aware
of such things).
But today, around here at least, it seems impossible to
make them flush, other than the occasional accident. If
the manhole isn't an inch or two below the road, then the
manhole itself will be flush, but surrounded by a moat 6
to 8 inches wide, which is an inch or two below the road.
Certainly this is one area where modern technology isn't
They have those - it's a simple ring that sits on the top of
the housing to lift the cover up by 3/4 inch (*). I have one
- for some reason one was left in the middle of the sidewalk
when they resurfaced roads near me, so I picked it up and
brought it home.
But the problem of uneven manholes exists on both new and
resurfaced roads around here. Some of it seems to be a
failure in paving (the pavement being above the manhole),
and some of it seems to be a problem of subsurface prep
(the subsurface compacting, leaving the manhole above the

I nicked 100 here on Labor Day, and should hit it briefly around 4-5 again

roof repairs, not on full replacements. Thankfully, I only had one of thos

a dark brown shingle roof. It was an emergency repair for a great client
and I had no choice. I had red burns on my knees and down the side of my l

I remember 40 years ago I would work all day as a laborer, than get off and
go eat pizza and drink a schooner of beer (or more!) to cool off. Now...
I get off, go cool off in a fast food joint and drink tea, then go home and
take some Advil. After showering, I drink more tea, eat some dinner, work
on paperwork and go to bed.
Even my guys tease me. "Hey Robert, we're going to stop for a six. You wa

ust day, I might just take them up on it.
