Abstract
This paper presents correlations between penetration index measured from dynamic cone penetrometer (DCP) and properties of pavement layer materials. A series of DCP tests were conducted both in the laboratory and in the field. The DCP data were analyzed and interpreted to generate a representative value of penetration per blow or DCP penetration index (DPI) for the material being tested at a given test condition. Basic properties of pavement layer materials e.g. crushed rock base, soil-aggregate subbase, sand embankment, natural subgrade etc. were tested and reported herein. By achieving appropriate moisture content and compaction quality, the empirical relationships between DPIs and properties of pavement layer materials from different test conditions indicated reasonable trends and thus confirmed its potential adoption for routine pavement layer evaluation in Thailand.
