Abstract
Perkerasan beton berpori merupakan salah satu bentuk
perkembangan infrastruktur dalam menangani aliran
permukaan. Kuat tekan yang dimiliki beton berpori cenderung
rendah akibat jumlah rongganya yang banyak. Serat polipropilen
merupakan inovasi untuk memperbaiki sifat tertentu beton.
Penelitian ini dilakukan dengan tujuan mengetahui pengaruh
serat polipropilen dalam campuran beton berpori.
Pembuatan sampel beton berpori dengan faktor air
semen (w/c) 0,3. Agregat kasar menggunakan batu pecah
Pasuruan dengan variasi rasio agregat semen (CA/C) 4; 4,25;
4,5. Serat polipropilen MasterFiber ukuran 48 mm dengan
variasi kadar 0%;0,6%;1,2%;1,8%. Pengujian kuat tekan, kuat
lentur dan laju infiltrasi dilakukan pada sampel umur perawatan
28 hari. Sampel berbentuk silinder 10x20 cm untuk uji kuat tekan,
dan sampel berbentuk balok 40x10x10 cm untuk uji laju infiltrasi
(porositas) yang kemudian digunakan untuk uji kuat lentur. Uji
laju infiltrasi menggunakan alat modifikasi dari peraturan ASTM
C 1701/C 1701M.
Kuat tekan beton berpori meningkat dengan kadar serat
0,6% dalam campuran. Apabila kadar serat ditambah, maka
ikatan yang terjadi dalam campuran semakin melemah, sehingga
kuat tekan menurun. Sedangkan kuat lentur dan laju infiltrasi
meningkat apabila beton berpori mengandung serat. Hal ini
dapat disebabkan oleh serat polipropilen yang terdistribusi secara optimal mampu bekerja di bidang patah dan meloloskan
aliran air dengan baik dalam sampel.

Pervious concrete pavement is one of infrastructure
development in dealing with surface runoff. Pervious concrete
has low compressive strength due to the numbers of pore.
Polypropylene fiber is an innovation to improve specific
properties of concrete. The purpose of this research is to find out
the effects of polypropylene fibers in a mixture of pervious
concrete.
The samples of pervious concrete with water-cement
ratio (w/c) of 0.3, using Pasuruan crushed stone as coarse
aggregate with coarse aggregate-cement ratio (CA/C) variation
4; 4.25; 4,5. The polypropylene fibers, Masterfibre, size 48 mm
with variation of the levels of 0%; 0.6%; 1.2%; 1.8%.
Compressive strength, flexural strength and infiltration rate test
performed on samples aged 28 days of treatment. 10x20 cm
cylindrical samples for compressive strength test, and samples of
40x10x10 cm shaped beam to test the infiltration rate (porosity)
which was then used to flexural strength test. Infiltration rate test
using a modification of ASTM C 1701 / C 1701M.
Compressive strength of pervious concrete increased
with 0,6% in mixture.The higher fibre content, the weaker
bonding inside the mixture, so that compressive strength.
Whereas, flexural strength and infiltration rate increased at
fibrous pervious concrete. It caused by polypropylene fibre which distributed optimally is able to work in fracture surface and
allow the water flow in the sample.
