Research on Paving Temperature Segregation and Rolling Uniformity Evaluation Method of Asphalt Pavement

in this paper, the temperature data of discrete points collected by the paving temperature real-time collection equipment, are expanded into surface data through interpolation, smoothing and other algorithms. Based on the temperature difference as the criterion for temperature segregation, the temperature distribution area is introduced as a control parameter, so as to establish the temperature segregation index (TSI) and low temperature area index (LTAI) to quantify and analyze the unevenness area of the paving surface. In addition, by defining the rolling uniformity index and rolling compliance index, the rolling uniformity of asphalt pavement are quantitatively evaluated, providing auxiliary support for highway construction management.
