Calibration and Implementation of Miniature Electronic Cone Penetrometers forRoad and Highway Design and Construction Control

摘要

A prototype miniature electronic cone penetrometer system is developed for roadand highway design and construction control. The equipment is implemented in front of the Research Vehicle for Geotechnical In Situ testing and Support (REVEGITS). A calibration chamber system for laboratory calibration and development of correlations is also fabricated and calibration tests performed. Initial correlations relating soil compressibility modulus, soil dry density and CBR with cone resistance are developed.
