This method is still in use.From learning to heat tar, they could make mounds of heated, gooey asphalt which was manually shoved and applied to a road bed after grading. Rolling and compression was done manually. Asphalt started being used after WWII. But it was more expensive than heated tar liquid and gravel preparations.Cement poured roads came in with making highways and toll roads, about 1965-69. Example: I-76 in PAHowever, even today, they still use asphalt patching. Rural areas still use tar and gravel which is cheaper for townships to maintain their roads. Coal produced reddog for roadways lessened after coal works closed down.Typically, you can tell what roads are state maintained (cement with asphalt patches), versus town (asphalt paved), versus rural or township (tar and gavel, or asphalt as a special expenditure).
