AN EXPERIMENTAL STUDY CONCERNING THE USE OF BITUMEN EMULSION AND SOIL IN GRAVEL ROAD WITH THE GOAL OF IMPROVING THE ROAD'S STABILITY

Abstract

The tensile strength and abrasion resistance of the subgrade soils have a direct and significant influence on the long-term performance of pavement constructions.   In-situ subgrades usually are unable to offer the necessary support to attain and acceptably perform under the traffic loads that is being demanded by an ever-increasing number of environmental regulations.In this instance, we are using bitumen emulsion in conjunction with soil in order to boost the durability of pavements as well as their lifespan.  

                               The vast majority of emulsions are put to use in surface treatments. The low viscosity of the emulsion, in comparison to that of hot-applied bitumen, gives the emulsion superior penetrating and spreading capacities. The kind of emulsifying agent that is used in the production of the bituminous emulsion is what decides whether the emulsion will be anionic or cationic. The most common use of bitumen in modern times may be found in the paving business, both for new construction and routine maintenance. The specific gravity of the soil is 2.68, the liquid limit is 33.75%, and the plastic limit is 21.56%. Other physical features of bitumen emulsion include the compaction test using the modified proctor test and the California bearing test at the value of 2.5mm,5mm,7.5mm,10mm with the loads
