Durability and Strength Analysis of Cement Treated Soils for Sub-Base and Base Layers of Pavement

Abstract

The development and growth in economy of the country is primarily depended on the connectivity within the country and region around. The basic and most utilized for of transportation used is the roadways and highways transportation. Good quality metal aggregate is required in large quantity for construction of roads which is scarce in nature. One alternative to this problem is to use the locally available soil by stabilising it with help of cementitious material so that it can be effectively used. The strength and durability are the basic requirements for any stabilised material to be used for road construction and thus in this paper the strength and durability characteristic of 3 soils treated with cement has been tested. The test used for strength evaluation is CBR test & 7 day UCS test and wet-dry durability test has been considered for durability evaluation for cement treated soils. The minimum dosage of cement based on then residual strength and mass loss percent criteria was calculated. It was reported that the amount of cement required for stabilisation is largely depended on the type of soil and vary accordingly.

Advancing Infrastructure in Developing Nations: A Synthesis of Ai Integration Strategies for Smart Pavement Engineering

“…It should be noted that this strategy brings pavement quality while saving money, essential for less developed states economies (Jordaan & Steyn, 2021). Sharma, Bhardwaj, and Nagar (2019) provide a discourse on the economic aspect of implementing cement-treated base in flexible paving thus, offering insight on an economical approach to highly sophisticated pavement technology. In this regard, AI is one of the most important factors that can facilitate more accurate predictions of pavement life cycle and maintenance requirements.…”

Various Alternatives in Flexible Pavement Design and their Suitability

“…3) Sharma H. 1 , Bhardwaj H 2 ,. & Nagar, D 3. (2019) "Economic Analysis of use of Cement Treated Base & Sub-Base in FlexiblePavement": Cement treated flexible pavement layer require less thickness as compared to conventional pavement because the loads are distributed over a large area.…”

“…1 , Sharma S 2 ,. & Sachdeva S. N 3. (2018) in their study "Thickness Reduction in Flexible Pavement Using Cement Treated Base and Sub-Base" observed that use of CTB and CTSB saves the material cost, transportation cost, maintenance cost.…”
