Abstract: The aging process of daspal on paved concrete pavement layers occurs during mixing in the Asphalt Mixing
plant and the time of service life. The process of aging of the daspal when mixing is called short-term aging
and aging of the daspal during the lifetime of the road service is called long-term aging. The study was
conducted in a laboratory with an oven method for simulating aging. The short-term aging method (Short
Term Oven Aging, STOA) is the testing of the specimens at 135
0
C before compacting for 4 hours representing
aging of the daspal mixture at the time of production of the asphalt mixture from on-site carriage to sealing.
The long-term aging testing methods (Long Term Oven Aging, LTOA) was performed 85
0
C after the
condensation for 48 hours representing a service period of 5 years. The aim of this research is to know the
effect of the process of daspal aging with respect to concrete asphalt. The research covers the value of
Stability, Flow, Marshall Quotient, VIM, VFB, Density, and Indirect Tensile Stiffness Modulus. This research
uses the optimum modification of the basic composition of resin (100 gr of pure resin or chunks + 350 gr of
dammar powder), fly ash powder (150 gr) and cooking oil (205 gr) and 4 % latex mixed by way of cooking
at temperatures below 150

1 INTRODUCTION
The development of highway construction is very
rapidly developed, where all human activities are
using land transportation, so the construction and
maintenance of the highway is the main concern of
the government, to get a sense of security,
comfortable for the users of the highway. One of the
causes of a decrease in the strength of the mixture on
the flexible pavement is the aging process. According
to Huber and Decker (1995) in his research entitled
Engineering Properties of Asphalt Mixtures and the
Relationtiship to Their Performance which refers to
the ASTM method says that the short term ovulation
process (Short Term Oven Anging, STOA), oven
done at 135
°
C for 4 hours before compacting. The
STOA simulation was carried out to determine the
aging of the asphalt mixture during the process of
preparing the dosage mixture of the dioxide mixing
base (AMP), during the transporting and spreading of
the field, while the Long Term Oven Anging (LTOA)
testing procedure was carried out at 85
0
C for 48 hours
after compaction. LTOA simulation is done to find
out aging of asphalt mixer during service period. In
the study stated that the test at 85
°
C for 48 hours
represents mixed ages for 5 years in the field.
Therefore, this research is done by making specimens
of STOA and LTOA by testing using Marshall Test
method so that the aging daspal mixture can be known
the level of air (porosity), stability and flow.
In this research will be aging process on
aggregate mixture with Asphalt Concrete Wearing
Course (AC-WC) coating, by making specimens
STOA and LTOA using Marshall Test. The AC-WC
mixture is used because it is a wear-resistant coated
top surface that has direct contact with the vehicle
load on it, which is affected by temperature so that it
undergoes aging.

Figure 1: Process of the specimens production.
One of the mixed performance parameters in the
flexible pavement is the durability of the pavement
due to weather and water effects. Road conditions that
are always submerged by water will decrease the
durability of the pavement layer of the pavement.
This becomes even worse when at the time of the
process of preparing a mixture of batches, during
transport, on-site deployment, and during the service
period aging on the dacal mixture, thereby reducing
the performance of asphalt pavement such as low
stability values, intercellular cavities or less dense
mixtures and bad durability. The parameters used to
see the durability level of the asphalt mixture are the
parameters used in comparing the stability test value
with the standard stability.
2 EXPERIMENTAL
2.1 Specimens Preparation
This research uses the composition of resin (100 gr of
pure resin or chunks blend to 350 gr of damar
powder), fly ash powder (150 gr) and cooking oil
(205 gr) and 4% latex mixed by way of cooking at
temperatures below 150
o
C (Haryanto, 2012). The
details of specimens production process is shown in
Figure 1.
After completion daspal modification, will make
the specimen samples.
Mix the aggregate and the asphalt according to the
result of the mix design of the optimum dosage
content.
Mix the mixture evenly in the presence of heating
to 150 ° C, then mix it in the mold.
The mixture is compacted with the compactor 75
times on both sides.
Provide code on each specimen.
The test object is silenced at room temperature,
then remove from the mold with the help of the
jack.
2.2 Test Procedure
The design of the baseball mixture begins by testing
the quality of the base material consisting of
aggregates and some materials, among the resin gum,
goring oil, latex, used oil, fly ash, which is presented
as a binder layer of dspal. The test standard used is
for job design mix testing based on SNI 03-1737-
1989 (BSN, 1989). Preparation of test specimens with
optimum dosage content of resin (100 gr of pure resin
or chunks + 350 gr resin pack or powder), fly ash (150
g), cooking oil (205 g) and 4% latex mixed by
cooking at below temperature 150
o
C. With this
optimum level, the test object will be tested for
resistance to short-term aging (STOA) and long-term
(LTOA).
The short-term aging method (Short Term Oven
Aging, STOA) is the testing of the specimens at
135
0
C before compacting for 4 hours representing
aging of the daspal mixture at the time of production
of the asphalt mixture from on-site carriage to sealing.
The long-term aging testing methods (Long Term
Oven Aging, LTOA) was performed 85
0
C after the
condensation for 48 hours representing a service
period of 5 years. Furthermore, to measure the effect
of weathering is done by measuring the stability and
melting with the Marshall testing apparatus
complying with AASHTO T245-74 (Braceras, 2015).
The research covers the value of Stability, Flow,
Marshall Quotient, VIM, VFB, Density, and Indirect
Tensile Stiffness Modulus with standard test

In this study, the analysis used the comparison
method with characteristic properties of the daspal
mixture with the characteristics of the mixed layer
AC-WC on the Bina Marga (2010) specification.
Later, the Inderect Tensile Stiffness Modulus test to
find the modulus of rigidity in purpose of designing
the thickness of daspal in the field.The AC-WC
mixture characteristics are shown in Table 1.
Indirect Tensile Stiffness Modulus is the most
conventional laboratory testing method to calculate
the asphalt stiffness modulus mixture. This method
became the UK Standard Draft for the Development
of BS DD 213 (BSI1998) and is similar to the resilient
modulus test described by ASTM D-4132 (ASTM
1996). According to standard, Indirect Tensile
Stiffness Modulus this test is a non-destructive test
and has been identified as a method for calculating
the average stiffness of the modulus of the material.

The result shows that in DP condition, STOA

requirement, it can be said that the condition of the

specimen above meets the requirements as a mixture
of coarse gradation AC-WC.
The value of stability has increased, this can be
seen with the result of 1906.48 kg in normal
conditions, 2290,61 kg at 5 years condition STOA,
and 2812,88 kg at 15 years condition LTOA. This
suggests that with added time of heating causes
locking between the aggregate particles and the
binding capacity of the aggregate becoming stronger,
as well as better cohesion and adhesion of the
carbons. However, the higher the stability the more
likely it can cause the pavement to crack and if too
low causing deformation. With a minimum
specification requirement of 800 kg, it can be
concluded that the condition of the specimen above
meets the requirements as a coarse-gradation AC-WC
mixture.
In the STOA condition, the MQ value has
increased from normal condition. In STOA condition
MQ value of 479.45 kg/mm while in normal
condition has a value of 421.45 kg/mm. This is due to
the aging process which causes evaporation/oxidation
to the daspal mixture so that the interlocking bond
between the aggregates and daspal increases,
resulting in the mixture having proven increased
flexibility. With the minimum specification
requirement of 250 kg/mm, it can be judged that the
condition of the specimen above meets the
requirements as a coarse-grained AC-WC mixture.
3.2 Indirect Tensile Stiffness Modulus
Indirect Tensile Stiffness Modulus is performed to
calculate the dispersion resistance capability of a
mixture on the pavement and back to its original
shape. After the manufacture of specimens with
optimum asphalt content (KAO), the ITSM tests of
each of the 9 test specimens were tested at 20
o
C, 30
o
C
and 40
o
C temperature using Material Testing
Apparatus (MATTA). Test Results Indirect Tensile
Stiffness Modulus is presented in Table 5.

From Table 5 it can be converted into a total graph
of the relationship between the Resilient Modulus of
the daspal and the varying temperature of the daspal
can be presented in Figure 2.
The value of ITSM is greater at lower
temperatures. This corresponds to the nature of the
asphalt becoming more rigid at lower temperatures.
Figure 2 shows that the results of ITSM on daspal
under STOA conditions decreased from 19378 MPa
values at 20
0
C to 9540 MPa at 30
0
C and 6029 MPa at
40
0
C. As for pure daspal (DP) conditions and daspal
of LTOA conditions also decreased in ITSM with
temperature rise. Thus, the daspal of STOA condition
has better values of ITSM than the pure daspal of
LTOA conditions. This suggests that the aging
process makes the daspal better than the daspal before
aging.
3.3 Daspal Thickness Design According
to ITSM Values
The outcome of flexible pavement thickness design
with SPDM Bisar 3.0 Software Program is presented
in Figure 14 as follows:

4 CONCLUSION
Based on this research with the effect of aging on the
characteristics of daspal using Bina Marga 2010
Specification, it can be concluded that the stability
value of the concrete mixture of the daspal has
increased significantly due to the aging of daspal in
the mixture. When value of daspal stability is too high
it leads to easy cracking. The flow value of mixture
slightly increased in STOA condition and decreased
in LTOA condition due to longer oven periods. The
void in the mixture (VIM) increased in STOA
condition and slightly decreased in LTOA condition
due to aging process. The value of void in daspal
(VFB) decreased in STOA conditions and increased
in LTOA conditions due to the aging process.
Indirect Tensile Stiffness Modulus (ITSM) value
under conditions DP, STOA and LTOA test
specimens can be concluded that the STOA is the
most effective condition because it has the greatest
rigidity modulus value.
The result of daspal pavement layer thickness
analysis with SPDM Software Bisar 3.0 method
concluded that in all temperature variation, it is better
to design the thickness of daspal layer based at the
temperature 20
0
C because the smallest thickness
design value (24 cm).
