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 applicable column names and descriptions to query the RC database for Phase I data.


The testing parameter for Phase I is as follows:  Maximum joint opening 15 mils, (15 x 10-3 in).




Sequential number used for sensor identification


Name assigned to the sensor. The first letters identify the sensor type:


T = Thermocouple

SG = Surface Strain Gage

LHDT = Potentiometer

CD = Crack Detector

COG = Crack Opening Gage


Temperature (ºF), Microstrain (strain x 10-6), Displacement mils (inches x 10-3), Voltage (v)




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

1= North (North only for Phase I)

Phase I had one overlay.

The name North is used for database consistency of future Phases.

Each sensor for Phase I is located the “North” section.

Display only field mapped to testsectID = 1. Display name = "North"


The number of the cycle.


(sensor response)

MR = Maximum Response

Only the maximum response of each load cycle was available for Phase I.


The value associated with the response MR
