This document discusses assessing the pavement condition and estimating the current asset value of a 6 lane-km road stretch in Karachi, Pakistan. Key steps included identifying distresses, calculating Pavement Condition Index scores for sections of the road, and determining an overall PCI of 77, indicating a satisfactory condition. Current asset value was estimated at 7.7 million using the road's initial value of 10 million and PCI score. The road needs only small maintenance to address some poorer sections.

Technology, Karachi

2. ∗ To select a 5 Lanes-km road stretch of Karachi
∗ To identify the type of distresses
∗ To compute PCIs
∗ To report Asset Value
Study Objectives

3. Study Area
∗ Siraj Road in P.E.C.H.S is
taken as Study Area
∗ The Length of the Road
is 2 km with 3-lanes
∗ So its actually a 6 lane-
km stretch road

4. Study Area
∗ It is a local road with
usual traffic jams in
morning & evening Peak
∗ Being a local road it is not
maintained properly and
have distresses on
different sections of the
road

5. Type of Distresses
found on the road
Pot Hole Corrugation

6. Type of Distresses
found on the road
Patching Edge Cracking

7. A numerical rating of the pavement
condition that ranges from 0 to 100 with 0
being the worst possible condition and
100 being the best possible condition
Pavement Condition Index (PCI)

8. ∗ ASTM D 6433 defines methodology for calculating
PCIs
∗ Data Collected based on the data sheets provided
in ASTM D 6433
∗ Data collected based on visual observation
∗ Road stretch was divided into equal segments of
300m for ease of data collection and more precise
data
Procedure of calculating PCI

9. Sample Form

10. Density % Formulas
Density = Distress amount in square meters x 100
Sample area in square meters
or
Density = Distress amount in linear meters x 100
Sample area in square meters
or
Density = No. of Pot Holes x 100
Sample area in square meters

∗ The average PCI of Road
Stretch is found to be 77
∗ The Overall rating of this road
stretch is found satisfactory
∗ The Road stretch needs small
maintenance.

14. Current Asset Value Estimation
∗ Approach A

15. ∗ Initial asset value is 10M
∗ Residual value is 1M
∗ Age of Asset is 5 years
∗ Remaining service life (RSL) is 5 years
Assumptions for Asset Value Estimation
∗ Approach A

16. ∗ Depreciation to date = (10M – 1M) x 5
5+5
= 4.5 M
∗ Current Asset Value = 10M – 4.5M
= 5.5 M
Current Asset Value Calculations
∗ Approach A

17. ∗ Initial Asset Value = 10M
∗ Pavement Condition Index (PCI) = 77
∗ Current Asset Value= Initial Asset Value x PCI
100
=10M x 77
