Plant available moisture in stone-soil media for use under pavement while allowing urban tree root growth.


Grabosky, Jason, Haffner, E., & Bassuk, N. (2009).

Journal of Arboriculture, 35(5), 271.





The research looks at the moisture content under constructed infrastructure and the growth of tree root systems. The experiment looks at various media used for pavement- gravel, concrete and different kinds of structural soils to find the moisture retention capacity of each. The use or consideration of porous aggregates could be factored in when assessing irrigation needs in normal operations, but should not be assumed to be the only criterion for determining the overall performance of a mix design. Soil chemical aspects such as aggregate and soil pH and cation exchange capacity ought to be further tested and considered over time. Aggregates must function over time as the load-bearing lattice of the system.
