Cost effective maintenance of pavement sections requires timely preventive maintenance
and planned rehabilitation treatments. Knowledge of the increase in condition due to
application of treatment and the loss of condition after treatment are essential when
deciding the maintenance and rehabilitation treatments. Any error in formulating these
values can cause significant changes in recommendations provided. Many researchers
have developed pavement performance prediction models; however, less research has
been done on the impact of treatment actions on the condition of a pavement section
after treatments. The objective of the research is to develop equations, using
deterministic empirical method, that predict the increase in pavement condition and rate
of decrease in pavement condition after treatment actions with respect to pavement
condition just before the treatment. The equations are developed for different treatments
and different functional class, and surface type combination to quantify the impact of the
treatment for the use in pavement management system. These equations can be used to
quantify the effects of different treatments for the use in pavement management system. Numerical illustration is presented using the data from the Metropolitan
Transportation Commission-Pavement Management System software developed by the
Metropolitan Transportation Commission (MTC) located in Oakland, California. A
relation is observed between increase in pavement condition and pavement condition just
before treatment for different treatments and different functional class and surface type
combination. Hence the equations to determine the trend in increase in pavement
condition for different treatments and different functional class and surface type
combination are developed. For rate of decrease in pavement condition, due to large
variability in the data the loss of pavement condition per year could not be related to
pavement condition just before treatment. Hence the equations to determine the trend in
loss in pavement condition after treatment could not be developed. The developed
equations can be efficiently used to predict increase in pavement condition due to
application of the treatment and the loss of pavement condition after treatment.
