Abstract: Available highway subgrade detection can pass really assess the status of the existing roadbed for the maintenance and reconstruction provided decision-making basis for engineering design .In subgrade de-tection is mainly introduced in this paper the main detection index and method of detection and gives some Suggestion on highway subgrade detection both has a positive reference value foe future similar projects.

Keywords: Highway both the subgrade;The main technical indicators;Detection method
