Dynamic ASG
Asphalt Strain Gage
Dynamic asphalt strain gages
measure axial strain in the flexible
pavement under high frequency
(dynamic) conditions. Utilizing four
active elements of a Wheastone
bridge circuit, this gage
compensates for temperature,
rejects
bending strain (may also be configured
to measure bending and reject axial
strains) and compensates for lead
resistance pro- viding a sensor that is
easily adaptable to most data
acquisition systems without
requiring additional signal conditioning.
These low modulus, ruggedized sensors are
built to withstand the high temperature and
vibratory rolled compaction required for asphalt
placement.
Each sensor is individually calibrated with
standard 30-ft lead length of high temperature
lead-wire attached (other lengths upon
request) and supplied with fabrication QualityControl documentation.
