A Comparative Study of Cement-Treated Sub-Base and Granular Sub-Base

Abstract

Abstract: It's no secret that countries around the world are fast progressing, and the infrastructure sector plays a critical role in this process. The infrastructure sector is heavily dependent on transportation. Compared to rivers, trains, airlines, and other modes of transportation, the majority of countries rely on roads and highways for transportation of all types. Crushed rock and murrum are common subbase materials for road construction in underdeveloped nations. In many locations, these materials are scarce and difficult to obtain. Fast transportation and conveyance are a top priority for India's Ministry of Road Transport and Highways (MoRTH). As a result, there is an enormous demand for building materials. The expense of producing the base layer material used in pavements, including as drilling, blasting, crushing, and transporting, makes it an expensive choice. However, when subjected to high traffic and/or strong weather, this material does not hold up. In addition, it is difficult to find in urban regions. Among the topics covered in this research are, the strength parameters of the road, total cost of construction and the time required for its construction. Comparative study of CTSB and GSB is explained in this paper. As a result, this material saves on construction costs by reducing the thickness of the crust. The Unconfined compressive strength, California bearing ratio of the cement-treated basis and sub-base is tested and results are obtained. It demonstrates that this material has superior strength and performance than that of typical materials when compared to those requirements. The CTSB methods saved the most money on construction costs of road, as evidenced by the findings. Using cement-treated foundation and sub-base instead of typical base material for road construction is shown in this paper.
