patched the 30-year-old asphalt
The road was reported as a 30-year-old concrete highway that workers were patching with asphalt, not a 30-year-old asphalt road.
Full reasoning
The cited contemporaneous reporting says the highway itself was concrete. The Baltimore Sun reported that when La Mancha Negra first appeared, "the government was patching up the 30-year-old concrete highway with asphalt when the first shiny blotches emerged." That contradicts the article's wording that workers were patching "the 30-year-old asphalt," which changes the road surface being described.
This matters because the material of the original roadway was part of the speculation around the stain's cause. Saying the highway was already asphalt is not what the source reports.
