Maintenance and repair technique

Road infrastructure must be maintained without significant deterioration in all types of weather and on a long timescale. Innovations in construction and maintenance materials have allowed longer intervals between the rebuilding of roads.


Sealants for concrete, asphalt, and steel are important to prolonging road life. Other chemical and polymeric material function as binder addictives to enhance the performance of asphalt roadways, for example, styrene-butadiene-styrene results in less rutting and cracking in Europe.

Thin lift asphalt maintenance overlays are utilized to extend the surface life of existing pavement.Thin lift asphalt maintenance overlays are utilized to extend the surface life of existing pavement.

Asphalt is able to generate energy. The Solar Roadway (United States) is a series of structurally-engineered solar panels that are built in the asphalt of the highways and are driven upon. The idea is to collect energy to be used by approx. 500 homes per mile.
