Abstract

The study, entitled "the application of the Model as a means of Testing the density of light to the ground in the lab (Advanced Studies 1)". Backed by research from previous research, entitled "the application of the Model as a means of Testing the density of light for the soil in the laboratory", in previous studies of soil clays used example is the land of clays from the village of Baringan, the city of Palangkaraya. While soil samples in this study used is the land of the village of Palopat Sub-district of Padang Sidempuan PK, Southeast, or rather in the STA 500 Padang Sidempuan 4 heading Mandailing Natal. This study aimed to compare the CBR and UCS clay stabilized sand and cement for the pavement. The research aims to conduct an analysis of the maximum density of soil clays based on Models by as much as 33 collisions per layer as much as 2 layers obtained the maximum dry weight (γd max) and optimum moisture content (w opt) and SNI 1742:2008. If the level of the margin of error is obtained and has 5% < assessment of performance against the same heap, then the Model can be used as a means of testing the density of light to the ground in a lab that has the same standard with SNI 1742:2008.

Abstract

California Bearing Ratio (CBR) is the ratio between load penetration of a substance against a standard material with the depth and penetration of the same speed. While Unconfined Compression Strength (UCS) is the amount of axial load per unit area at the time of the test specimen to collapse or when the axial strain reaches 20%. This study aimed to compare the CBR and UCS clay stabilized sand and cement for the pavement. The results showed that the CBR value increases, the value rises with increasing UCS cement mix. Then when the stabilization of clay with a mixture of 12% sand and 10% cement values obtained UCS at 9.06 kg/cm2 and CBR of 66% thus, stabilization of clay Bukit Rawi qualify for base down the highway because of the value of UCS 9.06 kg/cm2 > UCS 6 kg/cm2 and CBR of 66% > 20%. UCS and CBR rise in value is due to that the addition of semen into adhesive media when it reacts with water. Media adhesive is then solidified and formed a hard mass so it would hold weight.

Untuk menentukan kuat tekan bebas (UCS) tanah lempung sebelum penambahan matos terhadap stabilisasi pasir dan semen 3. Untuk menentukan kuat tekan bebas (UCS) tanah lempung setelah penambahan matos terhadap stabilisasi pasir dan semen untuk lapis perkerasan jalan raya. Hasil penelitian menunjukkan, bahwa kuat tekan bebas (UCS) tanah lempung sebelum distabilisasi pasir dan semen sebesar 3.51 kg/cm2. Kemudian, kuat tekan bebas (UCS) Pada saat 0% matos pada stabilisasi campuran 28% pasir dan 6% semen nilai UCS sebesar 9.10 kg/cm2. Kemudian, pada saat 2% matos, nilai UCS makin bertambah didapatkan 10.92 kg/cm2 dan bahkan 4% nilai UCS makin meningkat hingga 11.18 kg/cm2. Kemudian, pada saat 6% matos nilai UCS terus makin bertambah hingga 11.44 kg/cm2 dan pada penambahan 8% matos, nilai UCS terjadi peningkatan cukup besar yaitu 13.78 kg/cm2. Sedangkan pada penambahan 10% matos juga mengalami kenaikan nilai UCS sebesar 14,56 kg/cm2. Berdasarkan hasil penelitian di atas, maka bahan tambah matos dapat meningkatkan nilai UCS dan memenuhi syarat sebagai subbase dan base jalan raya. Karena menurut Ingels dan Metcalf, 1972 (dalam Hardiyatmo, 2010), bahwa nilai UCS hasil > 14 kg/cm2 dapat dipergunakan sebagai subbase dan base jalan raya. Sedangkan menurut Ditjen Bina Marga yang didasarkan pada SNI 03-3438-1994 (dalam Hardiyatmo, 2010), bahwa campuran ini belum dapat dipergunakan sebagai subbase dan base jalan raya, karena nilai UCS hasil < 20 kg/cm2.
