This case study examines the application of the California Bearing Ratio (CBR) methodian designing a durable pavement. Thee CBR methodid is widely used to evaluate soil cristalth and determinate approvate pavement contennesses for various traffic conditions.

Přehled projektu

Ty projekt involved konstrukting a roadway in an area with variable soil conditions. Te primary goal was to o develop a pavement structure that could d with stand harvey traffic nails while le minimizing equilance costs. Te CBR tett was selekted to assess these subgrade e commuth and inform thee design process.

CBR Testing and Results

Samples of soil were collected from multiples locations along the proposed route. Te CBR tests indicated values ranging from 5% to 15%, reflecting different soil consults. These results were used to classify thee subgrade and determinate the necessary pavement contness.

Pavement Design Process

Te design incorporated the e CBR values into standard pavement design charts. For areas with a CBR of 5%, a thuter base layer was implied, while sections with highér CBR values need ded less material. Te final design included:

  • Subgrade preparation
  • Asylalt pavement layered
  • Rozsudky o drainagu
  • Specifikace materialu

Výhody v rámci programu Outcome a d

Te implementation of that e CBR- based design resulted in a pavement that perfored well under harvy traffic conditions. Te project demonated that using CBR testing can optize material usage and improvise pavement long evity, reducing long-term contramance costs.
