I thought the basic design driver for a runway is the aircraft landing impact it will take. Probably more critical because it's usually easier to make a runway longer than stronger.
1) Are taxiways usually built strong enough to take a landing? Seems like overkill.
2) What is the basis of numbering runways? An aerial view of Newark Liberty shows the main runways are 4 in one direction and 22 in the other. Obviously not numbered for the heading or bearing.
Thanks,

1) taxiway are strong enough for a large airplane to land on them but they are not built to handle repeated landing like a runway. If fact, the ends of the runway where the planes touch down are much thicker then the center portion.
2) runways are numbers depend on the compass direction the pilot sees when landing. South is a heading of 180 degrees and north is 360 degrees, drop the zero so a runway that runs north / south is numbered 18 and 36.
If an airport has two runway that run north /south, the numbers are 18L (L for left) and 36R (R for right ) for the runway on the east side of the airport. And 18R and 36L for the west side runway.
