Caltrans Pipe Bedding Sand
Caltrans Pipe Bedding Sand
(OP)
Working on a job where the spec for bedding is a max of 5% passing 200 sieve and 90-100% passing a no.4 sieve. We brought a fill sand to the job and the lab came back with 12% passing the no 200 sieve. Does this seem right for
" fill sand ". If so, does anyone have a suggestion of a sand type that will meet those gradation requirements ? A washed sand maybe? Any help would be appreciated.

ASTM C33 concrete sand will meet the spec and it's readily available, but it will co$t you.

My typical experience in California (years ago) was to require sand bedding material with a sand equivalent of 30 according to CalTrans test method 217. I'm not sure if your fill sand would meet this spec or not.
