Industry familiarity with density-based assessment for Quality Control (QC) purposes currently hampers the use of more accurate tests. An ARRB research project identified several alternative quality tests that have the potential to provide improved accuracy (as...
Density has historically satisfied a 1 parameter need in quality control assessment. Other quality parameters are assessed independently. But modulus and performance-based subgrade design aggregates influences such as density, moisture content, material quality,...
This study relates dynamic deflection modulus (from the Light Weight Deflectometer) with Field California Bearing Ratio (FCBR). The FCBR test was used to determine CBR on the field to counter practical problems associated with Lab CBR. The test results showed that...
Appendix A of this report, includes the Queensland Department of Transport and Main Roads (QLD DTMR) Draft Technical Note – Guidance on Use of Light Weight Falling Deflectometers (LWDs) to be Accepted as an Alternative Method for Verification of Earthworks Compaction...
This report synthesizes knowledge on national and international experiences and practices using non-nuclear devices and methods for compaction control of unbound materials. This includes: Types of compaction control testing devices used by state DOTs, including...
