Strengthening and Widening of Flexible Pavement

Abstract

Pavements are important for traffic to operate swiftly, safely, and seamlessly. Pavements can be classified as flexible or rigid in general. Flexible pavements have a low flexural strength and a flexible structural reaction. Stiff pavements can be distinguished by their stiffness and flexural strength. Rapid advancements in car technology have resulted in huge moving loads on pre-existing routes in an effort to reduce transportation costs. Existing roads, which were built on general principles, are unable to handle significant wheel loads, resulting in road degradation.
Designing a pavement is a challenging endeavor. Traffic loads is diverse and fluctuates on a daily basis as well as throughout the pavement design process. It is made up of a combination of vehicle, traffic load, axle type, and load distribution. Pavement materials react to stressors such as intensity, temperature, moisture content, loading rate, and so on. To estimate the level of pavement strengthening for updated existing routes, a traffic survey is required. Traffic studies in the region were used to establish the number of traffic lanes and road width, as well as the pavement design and cost analysis of the highway project. In these surveys, determining the average annual daily traffic may be the goal of the traffic survey (AADT). The expected work will result in a determination of whether the present surface has a suitable overlay. To accommodate traffic, the road needs be enlarged. Determine if the material of the pavement is adequate in light of its limiting value.
