Determination and Monitoring of Key Construction Control Indices for Low-Temperature Performance of Asphalt Mixtures Based on BIM Platform

The construction control indices were commonly used to ensure the quality of asphalt layers in process. However, relationship between and low-temperature performance is not clear. purpose this paper was investigate effect variations on mixtures determine key indices, propose method for monitoring these using Building Information Modeling (BIM) platform. evaluated by semicircular bend (SCB) test. A new prediction model critical strain energy release rate established evaluate layer. Five factors are considered performance, which gradation asphalt-aggregate ratio mixture plant, rolling temperature, segregation, temperature segregation. Orthogonal test (OT) results indicated that order importance affecting asphalt-stone ratio, gradation, molding temperature. influences segregation quantified study. Furthermore, monitored BIM platform developed research. In process layer, variation caused should be paid more attention pavement.
