The invention belongs to the field of road construction quality control, and provides a device which can be used for automatically monitoring the pavement paving thickness and ironing vibration frequency of a highway with high precision in real time. The device can be used for achieving real-time measurement on the pavement paving quality, can also be used for remotely sending measurement information to a database for follow-up quality evaluation application, ensures that the paving quality can meet design requirements, can perform real-time alarm on substandard conditions, and ensures that a statistical diagram is formed to be taken as the basis for relevant departments to carry out the paving quality management. Therefore, the device adopts a technical scheme as follows: a real-time monitoring device of the pavement paving thickness and ironing vibration frequency comprises a paving thickness and ironing vibration measurement device, a GPS real-time positioning device, an integrated controller and a data wireless transmission device (DTU), wherein the paving thickness and ironing vibration measurement device comprises a steel-made bracket, an inclined moving beam, a rubber wheel, an acceleration transducer and two tilt angle sensors. The device provided by the invention can be mainly applied to road construction quality control.
