Abstract
The California Bearing Ratio (CBR) value of the subgrade is a crucial parameter utilized in the design
of flexible pavements, as recommended by the Indian Roads Congress (IRC). The choice of materials
used in constructing the pavement can significantly influence its overall design and performance.
Pavements play an essential role in ensuring traffic flows smoothly, safely, and efficiently. Generally,
pavements are categorized into two types: flexible and rigid. Flexible pavements possess low flexural
strength and exhibit a flexible structural behavior under load. In contrast, rigid pavements are
characterized by their high flexural strength and rigidity. Many existing roads, which are designed
based on empirical guidelines, often fail to withstand heavy wheel loads, leading to their gradual
deterioration over time. To address this issue, various engineering parameters must be meticulously
determined through rigorous experiments. Soil samples are collected along the proposed road
alignment to assess soil properties such as consistency limits, particle size distribution (sieve analysis),
and CBR values. These parameters are then used to design the appropriate pavement thickness for
flexible pavements. Additionally, the road alignment is meticulously designed and established using
precise surveying and leveling techniques. In this study, the total length of the road being designed and
analyzed is 257 m. California Bearing Ratio tests were conducted in the laboratory to obtain accurate
and reliable data for the pavement design. This comprehensive approach ensures the pavement
structure can adequately support the anticipated traffic loads, thereby enhancing the road’s longevity
and performance.
