KEYWORDS: fly ash, lime, soil stabilization, pavement, subgrade ABSTRACT Pavement engineers have long recognized long term benefits of increasing the strength and durability of pavement subgrade soil by mixing in a cementitious binder during reconstruction or new construction. Federal and state highway engineers have a renewed interest in perpetual pavement which will benefit from

et al. [11] investigate the effect of stone dust amp; fly ash combine at different percentage on expansive soil. It was observed that at the optimum percentages, the swelling of expansive clay is almost controlled and noticed that there is a marked improvement in the other properties of soil. Mohammed Y.

usefulness of the stone dust and fly ash as soil reinforcement. The present investigation has been limited to the following studies, 1. To study the strengthening of soil of low bearing capacity. 2. To study the effect of stone dust in soil preventing intermixing of the soft subgrade and the harder sub base. 3.
cement and fly ash for soil stabilization. They concluded that the treatment with cement, fly ash and phosphogypsum generally reduces the plasticity index. The maximum dry unit weights increase as cement and phosphogypsum contents increase, but decrease as fly ash content increases. V. Ramana Murty et al. [15] study the efficacy of calcium chloride
Usually fly ash and lime stones are preferred for stabilizing the soil since they possess the pozzolanic property but the drawback with these materials are that they dont possess coarser soil
black cotton soil using two type of fly ash, viz. (1) fine and the Black cotton soil found in Marashtra using fly ash. Stabilization of soil was done at the various percentage of fly ash content. and were determined at different percentage of fly ash. Soaked and unsoaked also determined. Researchers (Phanikumar and Sharma, 2004; Osinubi and Stephen, 2005
Study on Stabilization of Black Cotton Soil by Using Stone Dust amp; Polypropylene Fibers Dhananjay Kumar Tiwari 1, At present waste materials like stone dust from crushers, fly ash from industry and plastic waste are in abundance at various parts of our country. These wastes not only create health problems but also its disposal is a great problem for our society. This paper deals with a
Prof. Ravi Shanker Mishra (2015) [9] had studied about the stabilization of black cotton soil by use of Fly ash, Ferric chloride and Stone dust. The soil samples were tested for liquid limit, plastic limit, OMC with Maximum dry density and CBR. He concluded that the liquid limit, plastic limit, Maximum dry density and CBR values are increased due to the adding of Ferric chloride %, fly ash 15% and stone dust
Soil amp; Base Stabilization: Using fly ash to strengthen the top 814 of subgrade can decrease the thickness of aggregate base and/or pavement (asphalt or concrete) needed to achieve the structural design strength of the overall pavement section. Again, it works best in sandy, silty soils, but is also a great option to stabilize existing aggregate base when performing parking lot repairs or upgrades.
Jan 20, 2015#0183;#32;Thus expansive soils can be potentially stabilized effectively by cation exchange using Fly Ash. He carried out investigations using Soma Fly Ash and Tuncbilek Fly Ash and added it to expansive soil at 025%. Specimens with Fly Ash were cured for 7days and 28 days after which they were subjected to Oedometer free swell tests.
ments are the most emergence problems happened in building constructions on soft clay soil. Fly ash and Lime stone dust are both waste substances typically an industrial waste which is commonly used for stabilization of soils. The requirement of stabilization is to improve the adequate strength of soil by adding lime stone dust and fly ash.
Stabilization of soil by using solid waste A Review, 2 Prof. Ravi Shanker Mishra (2015) [9] had studied about the stabilization of black cotton soil by use of Fly ash, Ferric chloride and Stone dust. The soil samples were tested for liquid limit, plastic limit, OMC with Maximum dry density and CBR. He concluded that the liquid limit, plastic limit, Maximum dry density and CBR
The primary reason fly ash is used in soil stabilization applications is to improve the compressive and shearing strength of soils. The performance of fly ash and stone dust was studied by conducting California Bearing Ratio (CBR) tests. Studies were made with different percentage of fly ash and stone dust. The results have shown that the fly
The poor soils like black cotton soil, expansive soil and highly cohesive soil which have CBR less than 3% can be improved by adding 2030% sand or stone dust. With this in view, the present work
Ali et al. (2011) presented the effect of stone dust and fly ash on characteristics of fly ash. They concluded that there is a marked improvement in the properties of expansive soil if stone dust and fly ash is mixed in equal proportions. There is a significant control in the swelling behaviour of the expansive clay. Similarly many researchersKamon et al.(1994),Yorimichi, K. et al. (1999
Jul 16, 2019#0183;#32;This mechanical stabilization resulted in increase in soaked CBR value by %% for three types of finegrained soils considered in the study. The mechanical stabilization with coarse aggregate or stone dust is also found to be more economical as compared to replacement of the soil with good soil of desired CBR value by more than 50%. Pavement construction tends to be relatively
Stabilization of soil by using solid waste A Review
As fly ash is freely available, for projects in the vicinity of a Thermal Power Plants, it can be used for stabilization of expansive soils for various uses. The present paper describes a study
