A STUDY ON THE MANUFACTURE AND USE OF BITUMEN EMULSION IN GRAVEL ROADS
Abstract: Soil is considered to be most basic construction material that has good shear strength due to the cohesion and internal friction among the soil solid particles. But due to much heavy loads coming from bridges, buildings etc. even soils having good shear strength can fail resulting in subsequent failure of the structures due to differential settlement. Many attempts have been made by numerous scholars in the history to increase the strength of soil by different methods including addition of lime, cement etc. Recent research is being carried to use non-traditional materials like Bitumen Emulsions etc. for improving the properties of soil. Bitumen Emulsions are usually dispersions of minute droplets of bitumen in water i.e. oil in water emulsions and are used to improve the cohesive strength of granular, low cohesion, low plasticity materials. They can also improve the integrity of road base, sub-base or sub-grade materials by resisting the damage caused by water. The final strength of roadway is developed as the mixture cools. Alternatively, the bitumen is diluted with petroleum solvents like kerosene until fluid and the final strength of the material only develops when the solvent evaporates. Bitumen emulsions provide an alternative approach in which the bitumen is liquefied by dispersing in water. Emulsions can be used with cold and wet aggregates, the final strength of the road material develops as the emulsions ‘sets’ – reverts to a continuous bitumen phase – and water is lost.
A LABORATORY STUDY ON IMPLEMENTATION OF BITUMEN EMULSION IN GRAVEL ROAD
Abstract: Ranging from the bottom, soil is one among nature’s most plenteous construction materials. Most sort of construction is constructed with or upon the soil. The foremost necessary a part of a road pavement is subgrade soil and its strength. If strength of soil is poor, then stabilization is generally required. The most objective of this experimental study is to improve the properties of the gravel soil by adding hydrocarbon emulsion. A trial has been created to use emulsion for up the strength of gravel soil expressed in terms of cosmic radiation values which can persuade be economical. During this study, the entire laboratory work revolves round the basic properties of soil and its strength in terms of cosmic radiation. Somewhat cement another to supply higher soil strength. It’s determined that glorious soil strength results by mistreatment bitumen emulsion with very little amount of cement used as filler. In this study, the whole laboratory work revolves around the basic properties of soil and its strength in terms of CBR. A little cement added to provide better soil strength. It is observed that excellent soil strength results by using cationic bitumen emulsion (CMS) with little quantity of cement used as filler. The appropriate mixing conditions for black soil with CMS Bitumen emulsion have been attempted. This is followed by deciding four particular material conditions to show the variation in dry density and CBR value to achieve the best possible strength properties of black soil. Here we use ideal soil of passing 600 microns IS Sieve. Key Words: bitumen emulsion, bitumen stabilization, black soil, CBR, liquid limit test, modified proctor test, particle size distribution, plastic limit, pycnometer, sieve analysis, specific gravity. 1.0
