The images below are of the recently tarred service lane at Oshodi, work here was completed barely 6 months ago.
So, apart from the obvious poor quality of work done, why & how exactly did the Potholes occur?
A thread ~
en.m.wikipedia.org/wiki/Pothole?w…
The Wikipedia post basically outlines the issues as a failure in the fabric of the road due to moisture beneath the road surface & fatigue from vehicle load.
The article points more at snow as being the moisture enabling culprit but we obviously don't have snow in these parts.
