QUESTION: how can one satisfied the inspection team that we laid the asphalt carpet thickness 38mm and now it will be 35 mm, plz tell me answer with reasoning

Answer
Dear Nadeem

You would base your arguments on engineering tolerances. You have a 8% of minus tolerance which have to be assessed according to the codes of practice and the contract. If it is not accepted you must force on  technical justification of allowance of 35 instead of 38 which will influence the payments. But it will justify not to rebuild the asphalt layer.
