In the decades that followed the State Highway Act of 1956, newer and better machines were invented and developed for laying pavement more quickly and efficiently. By the late 1960s, machines could lay down pavement over two lanes at the same time. Standards were created to quantify quality pavement. These standards now dictate the specifications for the pavement laid down on public roads and highways.
Developments in the asphalt industry continue today through scientific research. As the science of asphalt paving continues to make advancements, roadways of the future will be more durable, will last longer, will be laid down more quickly and replaced more easily. This is the inevitable progress of an industry that still uses the same basic components but continues to improve methods of use.
