Asphalt around perimeter of catch basin grate
Asphalt around perimeter of catch basin grate
(OP)
Does anyone know of an industry standard for the maximum height allowed for asphalt overlay surrounding a catch basin grate? Is there a rule of thumb, tolerance level etc.? Specifically where the asphalt meets the grate frame. Does it have to be flush or is there an acceptable height differental? The grate is in a rural road way if that matters. Please let me know if there are reference sources available such as ADA, ANSI, AASHTO etc..
Thank you,
John
