SUBGRADE SOILS - WordPress

SUBGRADE SOILS 4.1 Introduction The subgrade constitutes the foundation material for the pavement structure as highway pavements ultimately rest on the native soil (subgrade). Hence the performance of the pavement is affected by the characteristics of the subgrade. And one of the major functions of a highway pavement is to reduce the

Pavement materials: Soil

03/08/2009  California Bearing Ratio (CBR) test was developed by the California Division of Highway as a method of classifying and evaluating soil-sub grade and base course materials for flexible pavements. CBR test, an empirical test, has been used to determine the material properties for pavement design. Empirical tests measure the strength of the material and are

Subgrade - Pavement Interactive

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.

AASHTO Soil Classification System - AASHTO Chart

Besides Soil Classification on other criteria, the AASHTO Soil Classification System classifies soils into seven primary groups, named A-1 through A-7, based on their relative expected quality for road embankments, sub-grades, sub-bases, and bases.Some of the groups are in turn divided into subgroups, such as A-1-a and A-1-b.Furthermore, a Group Index may be calculated to
