Detailed Exploration of the Locking Point Concept in Mix Design

项目名称：	Detailed Exploration of the Locking Point Concept in Mix Design
摘要：	The project will use x-ray computed tomography and mechanical performance tests to evaluate the manner in which aggregate particles pack during mix design to assess whether there is a point where aggregates no longer pack but simply move around. This will be compared to empirical definitions of locking point, which try to define the same thing. Then contemporary performance tests will be used to quantify the performance consequences for alternate mix design practices that attempt to increase binder content and durability without sacrificing permanent deformation (rutting resistance).
