3.1! MOIS"#RE INDIRE$" DAMA%E

The purpose of this test is to determine tensile strenth of compacted mi;ture by measurin the

load required to pull apart of the specimen until it fails! The tensile strenth of conditioned

specimen is compared to the control specimen to determine the strenth ratio %TS<'! This test is

applicable on the cores of completed pavement!

3.1!.1 Spec&'e(s Reco(&t&o(&()

After specimen is cured for ,: hours2 dry of control subset it will be wrapped with plastic in

heavy duty2 lea proof plastic ba! =t is placed in a 77+1>/ %,$+#!$>C' water bath and let it

submered in water bath about , hours + 1#minutes! Water should be 1 in! %,$mm' above

specimen surface!

i! The specimen are placed in vacuum container supported a minimum of 1 in! %,$mm'

above container bottom!

ii! Then container is filled with water at the room temperature so that the specimens have at

least 1 in! %,$mm' water of above their surface as shown in /iure -!1#iii! ?acuum of 1# – ,) in @ partial pressure %1- – )7 5a absolute pressure' is applied for 

appro;imately $ to 1# minutes!

iv! The vacuum removed from the vacuum container and sample left submered in water for 

at least $ to 1# minutes!
