A pavement temperature monitoring system ( ) is used on paver vehicle ( ) that is capable of forming a pavement material mat ( ) upon abase surface ( ), as paver vehicle ( ) travels generally in a single direction. A temperature sensor ( ) can be either a thermal imager, a thermal scanner, or a thermal imager operating in line &ldquo;scan&rdquo; mode. The temperature sensor ( ) is mounted on a rear end ( ) of the paver vehicle ( ) in such a way that the entire width of the formed mat can be scanned or imaged. A display device ( ) is capable of receiving a plurality of electrical signals from the thermal scanner generating and displaying a graphical image ( ) of the formed mat temperature profile.

Temperature sensing for controlling paving and compaction operations

A controller is for a heating system of a paving screed including a screed plate. The heating system is connected with the screed and configured to transfer thermal energy to the screed plate and includes an actuator configured to adjust thermal energy output of the heating system. The controller includes a temperature sensor connectable with the screed and configured to sense temperature of the screed plate. The sensor is also configured to generate electrical signals proportional to sensed temperature. An electrical logic circuit is electrically connected with the sensor and is electrically connectable with the actuator. The logic circuit is configured to compare a temperature signal from the sensor with a desired temperature value and to automatically operate the actuator such that the actuator adjusts thermal energy output of the heating system so as to maintain screed temperature about the desired temperature value. The logic circuit is a microprocessor and the temperature sensor is preferably a thermocouple. The microprocessor has a stored software program that selectively configures the heating system for use with various types of screed heaters.
