New Test Method for Determining the Workability of Asphalt Mixture Using Wireless Particle-Size Sensors Under Superpave Gyratory Compaction
1. Scope
1.1 This test method covers the determination of the workability of the asphalt mixture during compaction using the wireless particle-size sensor. It is applicable to the asphalt mixture being compacted under the Superpave Gyratory Compactor (SGC) below 150?.
1.2 This test method is appropriate for laboratory-prepared and field-produced asphalt mixtures, regardless of the type or grade of the binder , the type or gradation of the aggregates, and whether Reclaimed Asphalt Pavement (RAP), Warm Mix Asphalt (WMA) additives, or any types of modifiers are used in the asphalt mixture.

Rationale
Workability is one of the main factors that influence the compaction quality and ultimately the performance of asphalt pavement.
This test method is used to generate information concerning the potential characteristics of handling, placing, compaction, and performance of an asphalt pavement.
This test method is used to design the WMA to achieve the best workability at a relatively low compaction temperature. The test method is used to determine the appropriate compaction temperature, and the dosage of the WMA additives or modifiers to achieve the best workability for the WMA and modified asphalt mixtures, including the waste plastic modified, crumb rubber modified, polymer modified, etc.
This test method is appropriate for laboratory-prepared mixtures and field-produced mixtures, regardless of the type or grade of the binder, the type or gradation of the aggregates, and whether RAP, WMA additives, or other modifiers are used in the asphalt mixture.
The title and scope are in draft form and are under development within this ASTM Committee.
