► HAVING DURABLE HIGHWAY pavements is of the utmost importance for departments of transportation around the country. But how can it be achieved?Getting longer service life out of highway pavement is more than an economic imperative; increasingly, it is a matter of sustain-ability and resiliency, as well. When a life-cycle approach is taken-that is, an approach that includes not only pavement design and materials phases, but construction and end-of-life phases, as well-there is a clear benefit in continuing to utilize an in-place structure for as long as is feasible.Concrete pavements offer long-life design and do not need to be regularly replaced, making concrete an excellent choice. |
