Response Summary View

Contains information summarizing the results of the Reflective Cracking Phase testing cycles, including Sensor id, sensor name, sensor type, test section id, cycle number, response, response value, and response time. Below are the column names and descriptions to query the RC database for Phase IV.

The testing parameters for Phase IV are as follows: Target temperature at overlay bottom 32 ºF, maximum joint opening 12 mils, (12 x 10-3 in), cycle time 150 seconds and rest period 600 seconds.

Sequential number used for sensor identification.
Name assigned to the sensor. The first letters identify the sensor type:

POT = Potentiometer

LVDT = Linear Variable Differential Transducer

JDG = Joint Displacement Gage

EG = Embedded Strain Gage

SG = Surface Strain Gage

T = Thermocouple



SensorType Temperature (ºF), Microstrain (strain x 10-6), Displacement mils (inches x 10-3), Force (lbs)


Unique number assigned to identify each of the two test sections. 

1 = North and 2 = South


The number of the cycle.


(sensor response)

Refer to "Sample Strain Gage Response" image below

OL = offset left (first reading)

MRL = Minimum Response Left

MR = Maximum Response

MRR = Minimum Response Right

OR = Offset Right

The value associated with the response.
The time associated with the response. 
Unique id associated with the specific testing parameters for the corresponding phase.
