Scope and Objectives
Objectives:
•
•
•
•
•
To provides the means of developing annual work
programs, resource requirements and budgets.
To ensure an equitable distribution of funds over
the country or locality and to enable priorities of
allocations to determined in a rational way when
available funds are inadequate.
To authorize and schedule work.
To provide a system of monitoring the efficiency
and effectiveness of maintenance works.
To provide comfort, convenience and safety to
the road users and minimize the total cost of
maintenance measures and road used cost.
Scope:
• To explore the
use of GIS and GPS for the
development of a PMMS.

Conclusions
•
•
•
•
•
•
An urban road network in Tiruchirappalli City
containing 19 roads of 15.250 km was analyzed to
highlight the pavement condition of 25 m sections
of each road.
Pavement Condition was studied for four seasons
during pre-monsoon and post- monsoon in each
half year.
Roughness details of the road sections were
collected for three seasons. It was observed that
the IRI value on the roads varied from 2.5 m/km to
5.5 m/km.
The progression of various distresses with and
without maintenance works was studied.
For majority of the road sections, 25 mm SDBC
overlay at an earlier stage was found to be the
optimum solution over 40 mm BM at a later stage.
In HDM – 4, budget allocation for a specific year
on road maintenance to a particular road section
was done based on maximum budget utilization
technique.
