In less than 35 hours, Central Paving Corporation, an Iowa contractor, paved a mile long strip of a country road and reopened it to traffic. The joints were sawed and sealed, and the shoulders were complete. Opening the road to traffic so fast required using a concrete that developed strength quickly. After only 8 hours the flexural strength was 330 psi, and at 26 hours, beam breaks reached 780 psi. This project shows that fast-tracking isn't limited to overlay construction. The method is also advantageous for new construction of country roads, city streets, and highways.
