The Road Test scheme did not specify a test method for determining soil support capacity of a given soil. However, some means to correlate the hypothetical soil support values (S) and strength values resulting from a selected test method would be desireable. Correlation of Kentucky CBR's and soil support values was the main concern of this study.

Abstract. Three slightly different correlations between Kentucky CBR's and the AASHO Road Test soil support values were developed. The first relationship was made by assuming a logarithmic scale between Kentucky CBR's of 5.2 and 100, which corresponded to values on the soil support scale of 3 and 10, respectively.Cited by: 8

A Study of Correlation Between California Bearing Ratio (CBR) Value With Other Properties of Soil Dr. 1Dilip Kumar Talukdar 1Lecturer, Civil Engineering Department, Nowgong Polytechnic, Nagaon, Assam. India. 782001. Abstract--California Bearing Ratio (CBR) value is an important soil parameter for design of flexible pavements

What are the typical CBR values? The harder the material, the higher the CBR value. A CBR value of 2% is usually found for clay, high-quality sub-base will have CBR values between 80% and 100%, and some sands may have values around 10%. The CBR testing can be applied to soils with a maximum particle size of 20 mm.

This web applet, based on the conversion factors included in NCHRP Report 128, “Evaluation of AASHTO Interim Guide for the Design of Pavement Structures,” allows you to quickly estimate the Subgrade Resilient Modulus (M RSG) from either a California Bearing Ration (CBR) or Resistance Value (R-value) measurement. The conversion from ...

Figure 5-13. Schematic of stabilometer test setup for measuring R-value (Yoder and Witczak, 1975). 5.4.3 Elastic (Resilient) Modulus. Pavement thickness design prior to the 1986 AASHTO Design Guide was based on experience, soil classification, and the plastic response of pavement materials to static load, e.g., Marshall stability for asphalt concrete and CBR for unbound materials.Phone: (202) 366-1554

The “subgrade” is the in situ material upon which the pavement structure is placed. Although there is a tendency to look at pavement performance in terms of pavement structure and mix design alone, the subgrade can often be the overriding factor in pavement performance.
