Forensic study on rural road pavement failures along Parit Sumarto

Road deformation was occurred so prevalent on rural roads of Batu Pahat vicinity moreover when it's constructed on soft ground. This study presents the results of forensic investigation of a deterioration portion of the Parit Sumarto rural road. This road had been selected as represent of...

Forensic study on rural road pavement failures along Parit Sumarto
description Road deformation was occurred so prevalent on rural roads of Batu Pahat vicinity moreover when it's constructed on soft ground. This study presents the results of forensic investigation of a deterioration portion of the Parit Sumarto rural road. This road had been selected as represent of most common types of road deterioration found in Batu Pahat vicinity through field survey conducted for month in August, 2006.
