Construction Erosion Control – Rough vs Smooth Slope

Dramatic example of the effect of rainfall on a smooth versus rough slope. The rough side was “track walked” using a small Caterpiller tractor, the other side was “back-bladed” smooth with the same tractor. Both test plots were prepared with the same soil and then sprayed with bonded fiber matrix (BFM) with seed and fertilizer.

Unrolled Asphalt Berm Edge Clean Water Diversion

Here is another cool trick for keeping clean water out of your project. The contractor put down ATB (asphalt-treated base) and asphalt but didn’t roll (compact) the edge, which left a 3 or 4 inch berm. Clean rain water was kept on the asphalt rather than flowing off into the dirt shoulder and disturbed areas.

More Clean Water Diversion Best Management Practices

This shows several simple water diversion berms in action during a heavy rain. While the construction project is complete and the grass has grown, you can see how they prevented erosion during the project when bare dirt was exposed to rain.

Vacuum Sweeper Maintenance

If I specify a vacuum sweeper on a construction project, I expect it to be operational.

I require all systems to be functional per manufacturers specifications.

If not, the sweeper goes away, maybe the job is shut down, until a working sweeper is brought to the site.

Specifications:
1) Power brooms shall not be utilized without prior approval by
the Engineer.

2) Contractor shall have sufficient working vacuum sweepers on
site at all times work is being performed.

3) All sweepers shall have on-board water spray systems that
shall be operating at all times.

4) systems shall function per manufacturer specifications
including, but not limited to, spray water systems, blowers,
vacuum nozzles, hoses, debris hopper, hydraulics and
electrical.

5) At no time shall debris hopper seals leak debris and liquids.

Why Power Brooms are a Bad Idea

Filed under: Video — Tags: , , , , , , — Sheetflow @ 10:13 am

As you can see, these types of sweepers don’t pick up dirt and sediment from asphalt, they just spread it around.

Water spray system attachments help some but then the sweeper mostly turns the dirt to mud and smears it around.

These are useful for picking up gravel and sand.

A vacuum sweeper is the way to go.

Bonded Fiber Matrix BFM Needs to Cure Before it Rains

Bonded fiber matrix (BFM) needs to dry for 24 to 36 hours before it rains or else it can start to wash off.

Construction Erosion Inspection Hog Fuel Mulch Prevents Fugitive Dust

You are hauling dirt on a dry day and the dust is flying.
The water truck driver’s head is about to explode trying to keep up with the dust control.
Save yourself a Labor and Industries claim!
Use ground up vegetation (hog fuel)! Don’t haul it to the landfill.
