Chapter I- Introduction
Background of the Study
Puerto Princesa is a popular tourist city with many beach
resorts and seafood restaurants. It has been acclaimed severaltimes as the cleanest and greenest city in the Philippines.There are too many mineral resources that can be seen inPalawan such as nickel, copper ,manganese and also
bitumen. Bitumenis a term applied to native substances;petroleum, native asphalt, mineral, waxes, and asphaltites of
variable colors, hardness and volatility.

Coconut fibers can be used as a mixture to theasphalt to lessen the cracking; the fibers will
lessen the void spaces which are the primary
cause of the cracking.
The leaves from the Indian mango can be
extracted to get the color green pigment which
will be used to color the asphalt. These
innovations will improve the quality of the
asphalt that is used here in Puerto Princesa City.

Statement of the Problem
General: Will the mixing of bitumen and otherorganic component provide a good quality ofasphalt?
Specific:
Does the use of coconut fiber lessen the possiblecracking of asphalt?
Will the use of the extracted Mangiferaindica(Indian mango)leaves reduce the heat ofthe asphalt?
Do the use of organic component increase ordecrease the possible cost of the asphalt?

Objective of the Study
General: To provide a good quality of green asphalt
Specific:
To lessen the possibility of cracking of the asphalt To lessen the heat absorption by the asphalt
To lessen the CO2 that release from the asphalt
To reduce the probable cost of the asphalt mixtures

Significance of the Study
This experiment aims to enhance the quality of
cold mix asphalt by making it an ecofriendly green
asphalt, It reduces the chemical volume that isbeing release by the asphalt and it will be good for
the health of the community, it also strengthens the
quality of the asphalt by the use of other
aggregates.

Scope and Delimitation
The experiment will be conducted in threedifferent clean container, one with the CMA(Cold
Mix Asphalt), second is the asphalt with coconutfiber and the third is the green asphalt with thegreen pigment of Mangifera indica(Indianmango) and coconut fiber. The researchers willdifferentiate the three asphalts and it will bechecked by the PEO after 29 days for the
measurement of temperature and strength of theasphalt. This experiment does not cover thedurability of the asphalt.

Assumption of the Study
The researchers assumption of the study is to
obtain the objectives that is been proposed. First is
to lessen the heat applied in the asphalt and toobtain a higher strength and also to reduce the
possibility of cracking through the use of coconut
fibers and mango leaves.

Literature
Coconut fiber
The asphalt-fiber characteristics are tested to
determine such characteristics as the
penetration, softening point, burning point,
ductility, density, and Marshall immersion. This
condition creates a softer asphalt mixture,
which is prone to rutting (Fontes et al, 2010)

Fiber size affects the ease of mixing between the asphalt
and fiber: the smaller the fiber, the easier the mixing
process. (Civil and Environmental Research, 2012)
The results had shown that for mixtures of type SMA
(Stone Mastic Asphalt) the incorporated percentage of
coconut staple fibers, to a temperature of 70C, varied
between 0.5 and 0.7%. (Vale et al., 2006)

Green asphalt
Some say that dark-colored surfaces absorb
solar radiation instead of reflecting it. It has
been shown, however, that the UHI (Urban
Heat Island) effect is not a black and whiteissue. Density, heat capacity, thickness,
porosity, and a myriad of other factors affect
pavement surface temperature as well.
(LEED and Construction Building, 2009).

atural sand
Excessive natural sand contents can
increase the susceptibility of asphalt
concrete to permanent deformation-typedistresses. ( Reed B. Freeman and Chun-Yi
Kuo,1999)
