Starting on October 1st, 2016 the FAA is moving away from providing Mu values for runway friction reports to a new format showing contamination type and depth for each third of the runway. Along with the report is a code X/X/X showing runway condition codes for each third of the runway.

How do we, as pilots, use the field condition NOTAMs in calculating takeoff and landing performance?

From the FAA Improves Runway Conditions Reporting article:

The pilot or dispatcher would then consult the aircraft manufacturer data to determine what kind of stopping performance to expect from the specific airplane they are operating.

The important bit:

The FAA is advising operators to develop procedures for pilots and dispatchers that address the changes to runway condition reporting procedures.

Here are the corresponding braking coefficients:
