After the pavement is built up, to prolong its service life and reduce its maintenance expenses will become the important things. In order to make a rational maintenance plan, a thorough and accurate understanding in pavement surface situation is needed. In the past years, the measuring of the pavement surface state still depends on the handcraft or semiautomatic devices in China. These kinds of methods are not only low efficiency extremely but also need to close the transport. Now an intelligent equipment for pavement surface measuring is developed by Nanjing University of Science and Technology (NJUST). Its main technical performance has already reached the level of the international similar products.
