Macadam Install Notes.
Lay macadam to manufacturers’ guidelines.
Macadam advice notes:
Leave a 4-6mm gap between joined lengths of edging to allow for thermal expansion, hot macadam should not exceed 180C
As with all edge restraints, ensure adequate haunching or additional hard surfacing is in place before heavy compaction of macadam courses.
Ensure the first pass of the roller is 50mm clear of edge restraint subsequent passes can then proceed closer to the edging, final pass on the wearing course can pass over the aluminium edging.
