A publication that deals with the advantages of concrete road intersections is available from The Concrete Institute (TCI).
The 30-page Concrete Intersections, authored by TCI Managing Director, Bryan Perrie, explains, for example, why concrete intersections can better withstand the loading and turning movements of heavy vehicles.
“Heavy vehicles stopping and turning can stress the pavement surface severely along the approaches to an intersection. The pavement within the junction of an intersection may also receive nearly twice as much traffic as the pavement on the approaching roadways,” Perrie states in his introduction to the publication.
Concrete intersections, furthermore, offer advantages such as:
Low long-term maintenance costs;
No softening or deterioration caused by oil and fuel drippings;
Good light reflectivity that enhances pedestrian and vehicle safety at night and in inclement weather; and
A durable and skid-resistant surface.
Aspects of concrete intersections covered in the TCI publication include design considerations, concrete mixes, construction, opening intersections to traffic, vehicle detector loop installation, concrete-to-asphalt transition, and adding lanes to existing concrete pavements.
