[CANUFNET] Contents of Tree Root and pavement CANUFNET Digest, Vol 111, Issue 10

[Mike James]

Attached is some research by Orjan Stal, University of Sweden from early 1990s that might be helpful for Neal Aven in Surrey.
I shows that a tree root tip can exert 15bars  of pressure (217 psi).

Subject: [CANUFNET] Tree roots and pavement

Hi all,

I am currently searching for information related to the forces that tree roots exert.  The goal of my research on this topic is to work with an engineering firm to analyse these forces to inform building requirements in Surrey in order to give builders the specifications they need to install driveways and walkways that can better withstand the forces that tree roots exert.  The hope is that properly built driveways and walkways will then have fewer root heave problems in the future as our urban forest matures.

Do you happen to have any research at your fingertips on this topic?  Or any suggestions to direct my search?

Cheers,
NEAL AVEN
