Non-Compliance Test Reports
Dear Mr. Davis
After going thru our copies of CMJ reports and daily reports, the following
address each of those items.
CMJ Report No. 687-5192-040 Test No. 162 thru 169 was at sub grade elevation
before any lime had been added. I new we would be reworking the sub grade
with lime and be able to get passing density's.
CMJ Report No. 687-5192-055 Test No. 192 was retested on CMJ Report No.
687-5192-056 Test No. 197 thru 200.
CMJ Report No. 687-5192-100 Test No. 238.1 is identified incorrectly should be
a retest of Test No. 248 after reworking the sub grade it still failed. After
reworking the ground August 2nd & 3rd and each retest failing, the technician on
the 3m pulled another sample and ran a new proctor, and it passed on August41h
at 7:00 AM.
CMJ Report No. 887-5192-201 were the density test taken in the ditch failure at
Station 53+80, all three failed because of high moisture. When JT Dersner
employees pulled the material out to dry it up, they struck a Verizon 1200 pair
line. They continue to dry the material out and recompact it in place. I couldn't
reschedule CMJ for the 8th for the retest. Because of the pending weather, and
Dersner had already received their cement treated backfill, they installed it and
Verizon took over the excavation to make their repair.

It was raining on Dec. 11th no test could be taken. When CMJ tried to get
densities on the 12th Report No. 687-5192-203 on the cement treated backfill, too
much time had lapsed.
Lany I believe had Dersner been able to get retest on the 8th they would have
passed. Furthennore after Verlzon made thetr repair, Dersner filled the void
under the existing pavement with flowable fill. They also finished grading the sub
grade with f10wable fill.
CMJ Report No. 687-5192-184 was the concrete compression test for the pour
on Nov. 07 2006. TISeO Paving believes these cylinders might have been
damaged. Therefore we would like to do core's in the area of this test to preve
out the paving concrete strength.
If you need any additional information please feel free to contact me.
