>> Interesting fact to mention, except "construction materials" != asphalt.

Asphalt shingles are building materials, and it is definitely true that demand for construction materials in Texas is rising. Texas has a few shingle plants, and there are others in nearby states.

So we might say that "construction materials" != road building materials (though Texas is always in the process of building roads), and also that "asphalt demand" isn't entirely dependent on road building.
