Concrete played a major role in the construction of the United States’ highways during the since the 1950’s. Concrete can support heavy loads, such as truck traffic, with less deformation than asphalt. About 60% of the interstate system is concrete, especially in urban areas where Federal Highway Administration (FHWA) anticipates heavy traffic loads. Concrete was selected because of its durability, despite the initial higher cost of concrete over asphalt. Today concrete has become the least expensive alternative for new construction on a first-cost basis in addition to maintenance costs being generally lower. Fox Enterprises has had over 20+ years experience working on concrete roads and heavy highways all over the United States.
Concrete highway barriers prevent head on collisions and are designed to direct the vehicle back into traffic in the event impact by lifting it slightly when riding up on the angled slope, minimizing vehicle damage while the driver regains control. Barrier walls can also be used to block off closed roads or entrances.
