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.

The purpose of this study was to determine how much additional sand and cement on clay soil stabilization Bukit Rawi to the pavement. The results showed that after the addition of 16% sand with cement 2% the value of UCS rose to 1.63 kg/cm2 of initial conditions 0.41 kg/cm2. Then, the addition of cement 4% of the value of UCS also increased by 6.53 kg/cm2. On the addition of cement amounted to 6% the value of UCS will rise until 7.51 kg/cm2 and the addition of cement amounted to 8% the value increased to 12.08 UCS kg/cm2, and the addition of cement 10% the value increased to 13.06 UCS kg/cm2. Thus, with the addition of 16% sand and cement optimum 10% qualified technical foundation layer under the highway because of the value of UCS result 13.06 kg/cm2 > UCS 6 kg/cm2.

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.

Bukit Rawi clay soil properties only have a value of UCS at 0:41 kg/cm2 so it does not meet the technical requirements Lapis Foundation Under Highway. To that end, will be improved with the addition of sand and cement and is expected to meet the technical requirements highway pavement. The aim of this study was to determine how much the addition of sand and cement on clay soil stabilization Bukit Rawi for pavement highway. The results showed that after the addition of 12% sand with cement 2%, the value of UCS rose to 0:49 kg/cm2 of initial conditions 0:41 kg/cm2. Then, the addition of 4% cement, UCS value also increased by 4:44 kg/cm2. At addition of cement amounted to 6%, the value of UCS has increased to 5:29 kg/cm2 and the addition of cement amounted to 8%, the value of UCS rose to 7:33 kg/cm2 and the addition of cement 10%, the value of UCS increased to 9:06 kg/cm2. So that, with the addition of sand by 12% and 8% of cement optimum technically qualified foundation layer under the highway because of the value of UCS result 7:33 kg/cm2> 7:33 kg/cm2.
