Potholes with Pelon

  • A mini-series following my 44mm-high “Homies” character Pelon, where he poses for photo ops at potholes on the streets of Mount Tabor Park.<br />
Leadership fixes potholes, not patching.<br />
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city.  Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon. <br />
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal, except for the broken patch left of center – obviously a previous attempt to repair this same pothole – confirming this road never received the maintenance originally planned. The river-rounded pebbles of the base course layer tell the story of a roadway constructed originally from deficient materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice.  Finally, from the moisture visible in the pothole, and the shape of terrain at the road shoulders, it is clear that poor drainage has contributed to the failure of this road.  The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal; confirming this road never received the maintenance originally planned. The large cobbles of the base course layer tell the story of a roadway constructed originally from poorly graded materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  The conclusion is simple; this road has failed due to neglect and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal; confirming this road never received the maintenance originally planned. The size variation of aggregate chunks in the base course layer tells the story of a roadway constructed originally from well-graded materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  The breakup of pavement behind and to the left of Pelon – at the gutter – suggests that poor drainage played a role in this failure, and absence or repair has allowed water to saturate the base layers and complete the failure.  This road has failed due to neglect and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice.  Pelon is standing on concrete – evidence of a previous attempt to effect a repair – but that repair effort was doomed to fair because it was placed too thin, and was never going to be waterproof.  Poor drainage has contributed to the failure of this road.  The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  At this pothole, the asphalt layer is thick; confirming this road has received an overlay, but perhaps covering up this pothole without first repairing it. The base course layer is hard to characterize because the quantity of water present. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  This dangerous pothole, in the traveled way and where pedestrians cross, can be repaired by cutting out and reconstructing, but simply patching or overlaying will rapidly lead to a repeat failure, preventing a level of service – or service life – that should be reasonably expected of it.<br />
