ABSTRACT
Increasing number of traffic loads at present and future is a main issue in
highway construction. Factors such as durability, strength and economic need to be
consider into account in design and construction of road pavement. Many researches
have been conducted to explore material which can produce good properties for
asphalt pavement. This study was conducted to evaluate the suitability of OPFASH
as replacing material for alternatives filler with normal ACW 20. The asphalt cement
use varies from 4.5% to 6.5% and having penetration grades of 80/100. Marshall
Test was done to evaluate this study and compare the physical properties of
OPFASH Hot Mix Asphalt and normal Hot Mix Asphalt. The ACW 20 for the
normal mix aggregate and OPFASH does not satisfied JKR requirement for void in
total mix mean. The optimum binder content for the normal mix asphalt was 4.83%
and 5.13% for the OPFASH mix.

isu
utama
dalam
pembinaan
jalanraya.
Faktor-faktor
seperti
ketahanlasakan, kekuatan dan ekonomi perlu dipertimbangkan dalam merekabentuk
dan pembinaan jalan raya yang memainkan peranannya sebagai salah satu media
perhubungan yang terpenting. Banyak kajian telah dijalankan untuk mencari bahan
baru atau bahan ganti untuk menghasilkan ciri-ciri yang baik bagi turapan
berbitumen. Kajian ini dijalankan bagi mengkaji kesan terhadap ciri-ciri Marshall
dan kesesuaian penggunaan bahan OPFASH sebagai bahan penganti dalam
campuran panas asfal ACW 20. Kandungan asfal berbeza dari 4.5% ke 6.5% dengan
gred penembusan 80/100. Keputusan kajian menunjukan campuran menggunakan
agregat biasa mempunyi ketumpatan yang lebih besar tetapi campuran menggunakan
OPFASH akan mempunyai kestabilan yang lebih tinggi ACW20 campuran agregat
biasa dan OPFASH gagal menepati piawaian JKR lompang dalam campuran (VTM.
Kandungan asfal optimum untuk campuran biasa adalah 4.83% manakala 5.13%
untuk campuran OPFASH.

CHAPTER 1
INTRODUCTION
1.1 General
Road as one of land transportation infrastructure is very important in supporting
the economic for both regional and national development. The quality of material for
road construction will also influence the road performance. During 1900’s, the
bituminous paving technique was first used on rural roads and so as to handle rapid
removal of fine particles in the form of dust which was caused due to rapid growth of
automobile [Roberts et al. 2002]. Construction of highway involves huge outlay of
investment. A precise engineering may save considerable investment as well a
reliable performance of the in-service highway can be achieved. Two things are of
major considerations in this regard are the pavement design and the mix design (Das,
1998).
1
Nowadays, better techniques and methods have been developed and
implemented for improving roadway lifetime. Mix design is one of the factors that
play a strong role in roadway performance and life. A good mix design is expected to
result in a mix which is adequately:i.
Strong
ii.
Durable
iii.
Resistive to fatigue and permanent deformation
iv.
Environment friendly
v.
Economical
Asphalt mix design is a method of designing pavement structure. The process of
designing including selecting appropriate graded aggregate materials and optimum
bitumen content, so that the most suitable combination of composition and properties
will give required strength or stability to withstand repeated load applications and get
the most economic of pavement structure. For asphalt mix design, there are two mix
design methods which are Hveem Mix Design Method and Marshall Mix Design
Method. [Sandah, 2008]
Marshall Method was the commonly used in the Malaysia road construction
which is easy to conduct and simpler.
The Marshall Mix Design Method was
originally developed to address specific mix design issues confronting the USCOE
during World War II. Therefore, it was developed to be simple, light, quick, and
reasonably accurate for the wheel loading of the time.
2
Since then it has been
modified and supplemented to address new concerns but the basic testing apparatus
and selection criteria remain the same.
1.2 Statement of Problem
Nowadays, the road pavement or asphalt surface is exposed to higher loading
because of the increasing numbers of the transportation or vehicles on road. When
this road pavement is subjected to primarily repeat loading over a period of time, it
can caused to permanent deformation or rutting, fatigue, cracking and skidding
problems. Thus, the road pavement has a low durability and less workability. All of
these problems regarding to road pavement can leads to any unfortunately incident
such as accident.
For these several decades, lots of testing and researches had been done to find the
most suitable alternatives materials to improvise the road pavement. One of the
common alternatives ways taken in concern is by manipulating filler material in the
asphalt mix design. It is believe that modification of asphalt mix design materials
used may improve the rheological behavior of the mixes which provide the better
service life of the road pavement and strengthen the mix.
3
Traditionally aggregates, sand, bitumen or asphalt, and Portland cement are used
in road construction. The demand of these materials for construction purpose is
increased rapidly but naturally material become shortage in nature. The economic
factors relating to the materials used in construction mainly derive from the costs of
extracting the material, processing and hauling it to the site.
Besides that, the environmental disturbance is made up of factors such as
disturbance to the landscape leading to possible dereliction and the depletion of
natural resources. Disposal issue of the waste products is a challenge today. Some of
the materials are not biodegrade and often lead to waste disposal crisis and
environmental pollution (Chua, 2008).
For other alternative, industrial waste such as fly ash, blast furnace slag, colliery
spoil, marble dust, waste tyres are used in the road construction. For instant,
Malaysia is one of the largest countries that produced oil palm to other countries all
around the globe. This oil palm has caused an excessive waste from its production in
the factory and leads to disposal problem. Perhaps this oil palm waste can be used as
alternative filler in asphalt mix design.
By burning the waste of oil palm, it can produced oil palm fly ash or known as
OPFASH. Recently, OPFASH is found to be useful and economical alternative filler
replacing cement in concrete mix. However, the workability and capability of using
4
OPFASH is remaining unknown. It is hope that the used of OPFASH will decrease
the cost of construction and increase the quality of asphalt mixtures.
1.3 Aim and Objective
There were 3 objectives in this study that need to be achieved:
i.
Determine the Marshall properties of hot mix asphalt ACW 20 by using Oil
Palm Fly Ash (OPFASH) as a replacing material for alternatives filler with
normal ACW 20.
ii.
Evaluate the Oil Palm Fly Ash (OPFASH) suitability as filler in Hot Mix
Asphalt.
iii.
Compare the optimum binder content for both normal ACW 20 and Oil Palm
Fly Ash (OPFASH) ACW 20.
5
1.4 Scope of Study
In order to investigate the effects of OPFASH on Hot Mix Asphalt (HMA)
properties, the scope of the study was included preparation of ACW 20 Marshall
samples with bitumen content without additive were 4.5%, 5.0%, 5.5%, 6.0% and
6.5% as control samples. The Marshall Test was conducted to determine optimum
bitumen content and Marshall Properties. This research will be carrying out
according to the Marshall Mix Design and Marshall Stability and Flows test.
Total number of 15 samples of normal ACW 20 (control sample) and 15 samples
of OPFASH (modified sample) as the replacing material are prepared and tested
referring to the AASHTO manual. The result on the density, stability, flow, voids in
total mix, voids filled bitumen and stiffness from the modified sample and control
sample were compared and analyze according to specification stated in
JKR/SPJ/1988. All the sample preparation and testing was conducted at Civil
Engineering Laboratory (Concrete Laboratory and Highway & Transportation
Laboratory), Universiti Malaysia Sarawak.
