On The Road

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.

Geotechnical engineering can noticeably affect the sustainability of infrastructure development because of its beginning place in the construction practice. Utilization of waste materials for enhancing properties of the soil is a wise choice and is also one step towards accomplishing sustainable development. Application of by-products (viz., flay ash and rice husk ash) which could be defined as “sustainable materials”, find special place in the modern-day soil stabilization and modification exercise. The preset paper aims at enhancing properties of expansive soil with inclusion of industrial by-products namely Rice Husk ash and Fly Ash. Further the present paper focuses on improving geotechnical characteristics of fine sand upon reinforcing with ground shredded rubber tire. Fine sand has a low angle of internal friction and which in turn has low shear strength. Reuse of waste materials is one area of research which attempts to makes geotechnical engineering practice sustainable.

Deformation Properties

Geological disasters often occur due to expansion and shrinkage properties of expansive soil. This paper presents a cementitious material combined with rice husk ash (RHA) obtained from biomass power plants and lime to stabilize expansive soil. Based on compressive and flexural strength of RHA-lime mortars, blending ratio of RHA/lime was adopted as 4 : 1 by weight for soil stabilization. When mix proportion of RHA-lime mixture varied from 0% to 20%, specific surface area of stabilized expansive soil decreased dramatically and medium particle size increased. The deformation and strength properties of stabilized expansive soil were investigated through swelling test, consolidation test, unconfined compression test, direct shear test, and so on. With increase in RHA-lime content and curing time, deformation properties including swelling potential, swelling pressure, compression index, crack quantity, and fineness of expansive soil lowered remarkably; meanwhile, strength properties involving unconfined compressive strength, cohesion, and internal friction angle improved significantly. Considering engineering performance and cost, mix proportion of 15% and initial water content of 1.2 times optimum moisture content were recommended for stabilizing expansive soil. In addition, effectiveness of RHA-lime to stabilize expansive soil was achieved by replacement efficiency, coagulation reaction, and ion exchange.

Mineralogical Study

The paper presents the influences of different mix proportions of lime and rice husk ash (RHA) on compaction, strength properties, and durability characteristics of a local soil to evaluate the effectiveness of using RHA as a pozzolan to enhance the lime treatment of the soil. Mineralogical study was carried out also by using X-ray diffraction techniques to identify the reaction products that are responsible for the modification of the soil properties. In the mineralogical study, samples were analysed at different stages of curing. The results show that addition of RHA enhances not only the strength development but also the durability of the lime stabilized soil. Key words : soil stabilization, Atterberg limits, compaction test, unconfined compression test, X-ray diffraction.
