Case Studia: Ukończenie projektu Pavement Design Using Kalifornia Bearing Ratio (cbr) Metod

This case study examinates the application of thee California Bearing Ratio (CBR) methodin designing a durable pavement. The CBR methode is widely used to to o evaluate soil evatith and determinate appropriate pavement squatnesses for various traffic conditions.

Project Overview

Te projekty nie są już w stanie zbudować drogowej konstrukcji, która mogłaby być w stanie ciężkich traffic loads while minimazizing confidence costs. Te CBR tect was selected te subgrade thee confidents and inform thee design process.

CBR Testing andResults

Samples of soil were collected from multiple locations alongt thee proposed route. The CBR tests indicated values ranging from 5% to 15%, reflecting different soil contributions. These results were used te to classify thee subgrade and determinate thee necessary pavement squatness.

Pavement Design Process

Te design consignated thee CBR values into standard pavement designant charts. For areas with a CBR of 5%, a thicker base layer was required, while le sections with higher CBR values needed less material. The final design included:

Korzyści Outcome ands

Te implementation of thee CBR- based design result in a pavement that perfomed well under r heavy traffic conditions. The project demonstrant that using CBR testing can optimize material usage and improwizuj pavement longevity, reducing long-term contriance costs.
