Abstract
This report studies the e f f e c t s of increased truck t i re
pressures on pavement l i f e . These high pressures are contributing
to premature pavement f a i l u r e.
I n the study the impact of these i n f l a t i o n pressures was
examined using various combinations of load, t i r e type and
pavement structure. A computer a n a l y s i s was performed using
BISAR, an e l a s t i c l a y e r computer model. This analysis determined
the t e n s i l e and compressive s t r a i n s for each loading scenario at
various locations i n the pavement structure. Calculations were
then performed to determine changes in the pavement l i f e.
