Static sensors monitor temperature, moisture and crack status (resistance) on an hourly basis. Dynamic sensors measure quantities such as strain and pavement deflection in response to the load, and are triggered by the vehicle operations. Sensor data collected during traffic test operations will be processed and stored in. BACKGROUND. With the introduction of turbojet aircraft, braking performance on pavement surfaces has become more critical. Under certain conditions, hydroplaning or unacceptable loss of traction can occur, resulting in poor braking performance and possible loss of directional control. To address this.
