This book deal about the use and application of Light Weight Deflectometer for pavement evaluation. LWD rapidly assesses the in situ surface modulus of pavement layers. In this work LWD used to estimate in-situ surface and subgrade modulus and based on it rehabilitation strategies were framed. LWD test was conducted on 52 distress locations on a bituminous surface, WMM, GSB and Sub-grade. At the same test point location, field densities were measured, and samples were collected for laboratory testing. LWDmod software was used for finding back-calculated modulus for each layer. 90th percentile...

This book deals about applications of Nuclear Density Gauge tool and also significant comparison with conventional method such as a sand replacement method, core cutter and LWD for compaction measure. It is helpful for site engineer as well as students; whom are researching in Pavement field and Geo-technical field and also for contractor for rapid QA/QC work. To measure in-situ densities is a time consuming job, Nuclear Density Gauge tool measure within minutes and also evaluate moisture content. Nuclear Density Gauge tool significantly correlate with convention method, therefore it is...
