New Test Method for Effect of Moisture on Asphalt Paving Mixtures using Specimens Compacted with the Marshall Apparatus
1. Scope
This test method covers procedures for preparing and testing asphalt mixture specimens that were compacted with the Marshall apparatus for the purpose of measuring the effect of water on the tensile strength and tensile strength ratio (TSR) of the paving mixture by comparing conditioned (wet) and unconditioned (dry) samples. This test method is applicable to dense graded mixtures. This test method can be used to evaluate the effect of moisture with or without antistripping additives including liquids and pulverulent solids such as hydrated lime or Portland cement.

Rationale
The standard is being proposed because D4867, which currently includes both Superpave gyratory and Marshall compacted specimens, is being balloted to limit the standard's application to only Superpave gyratory specimens. This leaves the current users of the standard with a need to refer to another standard that is specifically for the Marshall compacted specimens. This standard will contain the information removed from D4867.
The title and scope are in draft form and are under development within this ASTM Committee.
