Thank you for your visit in this site and welcome. Don’t worry I will post more and try to post about your specialization just watch for it.
sir what it is mean the thickness of backfill should not be greater than 300mm in part 5.3.3?
Let say for example you have to backfill 900 mm thick then you shall have 3 layers. In every layer (300mm thick) you should compact it and perform compaction test before you proceed for another layer of backfill.
thanks for the learning sir! 🙂
You’re welcome barr! And thanks.
Can you post the ITP for this Excavation & Backfilling?
Hi Victor,
Sorry for this request. I’ve written this on my ebook and it is unfair to the people who have bought the ebook if I would post it. Hoping for your understanding.
