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.


9/19

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.

Chapter II - Review of Related

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.

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)
