INTRODUCTION
IKRAM PAVES Sdn Bhd was engaged by LZ Teraju Sdn Bhd to conduct
International Roughness Index (IRI) measurement using Ikram Road Scanner (IRS) for
Projek Menaiktaraf Jalan Persekutuan FT54 Dari Sungai Buloh Ke Assam Jawa,
Daerah Kuala Selangor, Selangor Darul Ehsan (Pakej 1, Sec 0+000 - Sec 14+000). The
route map is shown in the Figure 1.

OBJECTIVE
The objective of this report is to present the International Roughness Index (IRI)
compliance result. This IRI result was compared against JKR Standard Specification
(JKR/SPJ-2008) for the new constructed road as shown in Table 1.

SCOPE OF WORK
This exercise involves International Roughness Index (IRI) measurement using Ikram
Road Scanner (IRS). The field work was carried out on 04/03/2020 & 29/07/2020 with
a total length of 62.800 ln-km.

METHODOLOGY
The pavement functional condition was collected using IKRAM Road Scanner (IRS).
The IRS is one of the latest network survey vehicles developed by ARRB Transport
Research utilizing progressive technologies. This vehicle was designed to capture
pavement functional condition data, survey mapping information and roadside asset
details whilst travelling at highway speed. This fully-featured vehicle contains a
compact workstation capable of capturing and storing individual data elements for
roughness, rutting, texture and surface condition, as well as providing high-detail video
images of road and roadside assets.
The IRS is made of seven (7) packages which are the Profiler Package, Gipsitrac
Geometry Package, GPS Package, Video Package, Distance Package, Transverse
Profile & Rutting Package and Laser Crack Measurement System Package.
Figure 2: Ikram Road Scanner (IRS)
The Profiler Package is a digital, road profiling package that uses laser sensors to
accurately record the profile of the road surface such as longitudinal surface profile,

KUALA SELANGOR, SELANGOR DARUL EHSAN, (PAKEJ 1, SEC 0+000 - SEC 14+000)
road roughness and surface texture. This capability put the IRS survey into Class I
profile techniques - the same class as the rod-and-level survey, the TRL beam, the
dipstick and the walking profiler.
To measure the longitudinal surface profile, the Profiler Package measured and
recorded the vertical distance between the Profiler Package and the pavement surface,
the vertical acceleration of the profiler beam, time and distance at which the parameters
were recorded. International Roughness Index (IRI) is calculated based on the
longitudinal surface shape using a computer-based model of a quarter car suspension.

SUMMARY OF FINDINGS
Figure 5: Overall Roughness Distribution
Based on the result shown in Figure 5, 95% of the road was complied with JKR
requirement which roughness condition was below 2.0 m/km IRI. However, 5% of the
surveyed location was not complied with JKR requirement which the IRI is equal or
greater than 2.0 m/km.
Detailed IRI results as shown in Item 6.0 on the following page.
