Method for selecting an asphalt mixture for making an interlayer and method of making an interlayer

A method of reconstructing a roadway, said method comprising:

• providing at least one asphalt mixture comprised of a polymer binder and mineral aggregate wherein the mineral aggregate is present in the at least one asphalt mixture in an amount greater than about 89% and less than about 93% by weight of the at least one asphalt mixture, the polymer-modified binder mixed under low shear blending conditions;
• performing a stability test on said at least one asphalt mixture;
• performing a fatigue test on said at least one asphalt mixture;
• selecting an asphalt mixture for an interlayer after performing said stability and fatigue tests based on stability and fatigue performance of said at least one asphalt mixture;
• applying said selected asphalt mixture as an interlayer to said roadway;
• determining a desired thickness of an overlay to be applied to said interlayer based on traffic levels;
• and
• applying said overlay to said interlayer in said desired thickness.

A method of selecting an asphalt mixture for making an interlayer for a roadway, comprising:

• performing a ductility test on at least one polymer-modified binder;
• selecting a binder for making an asphalt mixture after performing said ductility test and based on said ductility test;
• providing at least one asphalt mixture comprised of said selected binder and mineral aggregate wherein the mineral aggregate is present in the at least one asphalt mixture in an amount greater than about 89% and less than about 93% by weight of the at least one asphalt mixture, the polymer-modified binder mixed under low shear blending conditions;
• performing a stability test on said at least one asphalt mixture;
• performing a fatigue test on said at least one asphalt mixture;
• and
• selecting an asphalt mixture for said interlayer after performing said stability and fatigue tests based on stability and fatigue performance of said at least one asphalt mixture.
