Stone Streets Research – Updated

Porphyry stone paved streets, along with other stones are the subject of amazing research in documenting old world techniques for laying this material that had previously only been an oral tradition, now based on engineering guidelines.

Due to previous interest in the stone paving guidelines from the Society of Chief Officers in Transportation in Scotland (SCOTS) we have sought out additional research and updated companion material to the SCOTS – NATURAL STONE SURFACING, Good Practice Guide, 2nd Edition, December 2004

You will want to download this further research and companion documents to add to your library of this important material.


  • Further Research – An evaluation of the technical, economic, and aesthetic performance of a selection of completed natural stone streetscape projects around the country (Scotland)
  • Development of a robust Whole Life Cost Model for natural stone streetscapes.
  • A review of street-cleansing practice around Scotland and how those practices impact the quality and durability of natural stone streetscapes.

The six new sections will round out and enhance the original document. If you did not have an opportunity to get the original guide, the download site can provide this document as well.

SCOTS Additional Research

Porphyry’s composition determines its high compression strength, resistance to stains, slip resistance, and high freeze/thaw ratings.  The stone is the most popular paver in Europe, and is favored for its flexibility in design, beauty, durability and low maintenance requirements. ADA Compliant Porphyry pavers are also adaptable to a permeable paving set. The stone is by far one of the most durable pavers in the world.  These materials are available from Milestone Imports.   –
