“The average life of an asphalt roadway around here is 10-12 years. But if you use a restorer with soy as its active ingredient right after the asphalt is placed, you automatically extend the pavement life. Further, if you re-treat the same road in four or five years, you add even more life to it.” “Even if the cost is eighty-five cents or a dollar a square yard, it pays off if it extends the pavement life an additional two years. If you can extend up to five years, which it usually does, you’re really getting a great return for that investment.”
