PENGARUH BAHAN TAMBAH POTONGAN LIMBAH MATERIAL PLASTIK TERHADAP KUAT TEKAN BEBAS PADA TANAH LEMPUNG WATES

Abstract

ABSTRACT
This research aims to classification clays in Kasongan Bantul based of AASTHO (American
Association of State Highway and Transportation Officials Classification) and to find out the
highest number of qu by using a mixed pieces of plastic material waste in percentage 0%,
1%, 2%, and 3%. This research was conducted in laboratory soil mechanics the Department
of Civil Engineering and Planning, Faculty of Engineering, Yogyakarta State University. The
results showed that Clays in Kasongan Bantul based of AASTHO is classified A-7-6 (11) that
is medium to low; the plastic material waste reveals the highest number of qu, that is on 3 %
that is 0,91286 kg/cm2; 2% that is 0,77660 kg/cm2; 1% that is 0,77354 kg/cm2; and 0% that is
0,65345 kg/cm2.
