Study of Improving Soil Using Permit, Corn Ash and Sodium Silicate

Abstract Soil that has low bearing capacity has a bad impact on the construction that is built on it as a result of which the building is easily damaged such as lifting the foundation on the building and causing cracks and shifting on the road. This research uses experimental laboratory methods. Soil samples used were taken from Lembang Tondon Siba’ta, Tondon District. Corn cobs were taken from Sa’dan Marante, Sodium silicate is obtained from chemical figures and palm fiber taken from Buntu Tagari and then tested for soil physical characteristics and soil bearing capacity in soil samples with a mixture of sodium silicate, corncob ash, palm fiber and soil without mixture. know the bearing capacity of the soil. The results of the research on stabilized soil by adding 0.2% palm fiber, 2% corncob ash and 3% sodium silicate obtained an increase in soil bearing capacity of 9.73% from the original soil and the addition of 0.2% palm fiber, 4% corncob ash and 3% sodium silicate.

Lime soil, literature [1] just gave a general rule to the mixture’s composition design. Because of the soil’s ingredient region difference, the reasonable mix of lime soil in special region must be determined by the test. This paper first quoted the formation of lime soil’s strength and the effect factor, and then regarded the non-side limitation compressive strength at different ages as inspection norm. Used orthogonal design method, the mix for the lime stabilized soil in Jilin area was investigated in this paper. The optimum mix and the main effect factor was determined by the strength at 28 days and verified by the regression strength at 90 days. In the meantime, the key problem had been summarized on the lime stabilized soil construction point and quality control.

The subgrade used for road construction should have a good bearing capacity, because the loads applied on the road construction are static and dynamic loads. If the CBR (California Bearing Ratio) value low so the subgrade of bearing capacity is not good. The purpose is to get the results of physical of the original soil, get the value of CBR laboratory of the original soil, get the CBR laboratory that has been stabilized using lime and rice husk ash, find out the optimum needs of lime and rice husk ash.Four original soil samples each of lime and rice husk had to go through an experiment by using 5%, 8%, 10% and 12% of lime and rice husk ash. The experiment results in water content w = 58.12%, weight of the soil γt= 1.44 grm/cm3, specific gravity Gs=2.11, Liquid Limit LL = 67.28%, Plastic Limit PL=54.06%, Plasticity Index =13.21%, maximum dry matter weight = 1.342 gr/m3 CBR= 5.13% physical properties of original soil; medium plasticity properties; 10% maximum CBR value at 69.046% lime; 10% maximum CBR value at 8.476% rice husk ash.

The subgrade is very important on road construction, because its functions for support the traffic loads. The subgrade is not able to bearing capacity the traffic load , can cause damage such as cracks, settlement,and deformation on the flexible pavement or rigid pavement. to solve in this problems, it is necessary to improve the mechanical properties of subgrade for increasing soil bearing capacity and reducing the swelling potential. The Sicincin ring road - Lubuk Alung, Padang Pariaman district which has deformed, settlement and cracks on the road pavement, caused by poor bearing capacity of the subgrade. To solve these problems, it is necessary to have the soil improvements (stabilization) for subgrade In this paper soil stabilization is done by mixing soil with lime and rice husk ash (variations in lime content of 5%, 8%, 11%, 14% and 17%) and rice husk ash (constant 2.5%) .The compaction test and CBR test is carried for each variation. The results in this study obtained the most optimal percentage of lime + rice husk ash is 11%, CBR design is 25%, and swelling value of 0.13%. CBR value of subgrade without lime and rice husk ash obtained CBR = 2.3%. So that there is a significantly increase in CBR value if using lime and rice husk ash as stabilization material for subgrade. These results can be used by experts to choose effective stabilization methods.

Abstract Porous asphalt is a pavement layer structure with aggregate gradations with a coarse fraction greater than 70-85% of the total weight of the mixture so that the resulting structure is more open and porous, which prevents water from stagnating on the road surface reduces water splash and makes the road less slippery. This study aims to analyze the permeability properties of a mixture of hot mix cold laid containing Asbuton in the form of porous asphalt. The research used was an experimental laboratory method. This study used Buton granular asphalt (Buton granular asphalt) with variations in BGA content of 4.5%, 5%, 5.5%, 6%, and 6.5%. The use of BGA is aimed at improving the performance of porous asphalt mixtures without using oiled asphalt. Manufacture of test objects through permeability tests. The results showed that the permeability value for the BGA content of 4.5% was 0.05 cm/s, the BGA content of 5% was 0.06 cm/s, the BGA content of 5.5% was 0.06 cm/s, the BGA content was 6%. is 0.03 cm/s and the BGA content of 6.5% is 0.02 cm/s.

The research evaluated the failure susceptibility of biopolymers (Guar Gum, Xanthan Gum, Bentonite) and polyvinyl acetate (PVAc) stabilized soil samples from three failed locations along Oshogbo – Iwo Road’s using the TDRAMS mathematical model formulated by Aderinola et al., (2015). The stabilizers were added to the soils in concentrations of (0.25-2) % Biopolymers, (1-3) % Bentonite and 2% PVAc. The samples were classified according to AASHTO as A-5 (slty-sand) and ML group (inorganic silts, sfine sands with low plasticity) based on USCS classification system. Geotechnical tests carried out on both natural untreated and treated samples showed that the natural soil samples gave OMC values of between (11.7-14.97) %, MDD (1644-1453.6) Kg/m3, and soaked CBR (2-6) %. 1% Guar gum, 1 % Xanthan gum, 3% Bentonite and 2% Poly vinyl Acetate were deduced to be optimal mixes for improved strength. However, Guar gum was observed to be the best stabilizer. With the TDRAMS model, 1% Guar gum reduced the failure susceptibility indices of the road by 11.02 % (i.e. from 127 to 113). However, for maximum benefits to be achieved from the stabilization, other factors like provision of good drainage facilities, adequate road sections etc. must be provided. This will help in improving the strength of the subgrade soils and overall durability of the road.
