Friction Surface Treatment Selection: Aggregate Properties ...

Specification requirements were established for the properties of calcined bauxite and steel slag for HFST and friction surfacing with respect to LAA, Micro-Deval abrasion, PSV, Al 2 O 3 content, and fine aggregate angularity (FAA). Specification requirements were also developed for HFST aggregate gradation and surface friction performance.

The aggregates just described all meet the Consensus aggregates properties for shape and have a 100 percent crush count. However, the basalt aggregate fractions tend to be much more elongated than the corresponding limestone aggregate fractions which tend to be more cubical. The basalt is twice as hard as the limestone aggregate as measured by Mohs hardness and

EFFECTS OF THE IGNITION METHOD ON AGGREGATE PROPERTIES

The loss of weight during this process is monitored, and an asphalt content is calculated, After the test is performed, clean aggregate remains, which then can be tested for gradation accuracy. However, some concern has been expressed in the ignition oven (i.e. 538 C) on the aggregates in an asphalt concrete mix. This paper reports on research regarding the accuracy of reported

Statistical Network Analysis - Purdue University

Statisticians have mostly concentrated on models of static networks, which focus on predicting the existence of edges between individual nodes, and do not attempt to model aggregate properties of the graph. In contrast, physicists have developed techniques to model global properties of large complex networks. Their models describe average statistics of the network and focus
