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 II.

The testing parameters for Phase II 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.

dbo.Response2
SensorID	Sequential number used for sensor identification.
SensorName	Name assigned to the sensor. The first letters identify the sensor type: EG = Embedded Strain Gage JDG = Joint Displacement Gage LVDT = Linear Variable Differential Transducer SG = Surface Strain Gage T = Thermocouple
SensorType	Temperature (ºF), Microstrain (strain x 10^-6), Displacement mils (inches x 10^-3), Force (lbs)
TestSectionID	Unique number assigned to identify each of the two test sections. 1 = North and 2 = South
CycleNum	The number of the cycle.
ResponseType (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
ResponseValue	The value associated with the response.
ResponseTime	The time associated with the response.
TestParameterID	Unique id associated with the specific testing parameters for the corresponding phase.
