Abstract

A promising direction for increasing the service life of asphalt concrete pavements is the creation of "smart" materials that can independently respond to changes in the structure during operation and take measures to eliminate them. The implementation of the technology of self-healing of asphalt concrete can be achieved through the use of encapsulated modifiers, which provide a reducing agent for a functional capsule. The simplest method for encapsulating modifiers is the self-healing alginate technology, where capsules with a reducing agent are produced through an aqueous solution of sodium alginate. It has been shown that alginates are an electrical tool that allows the use of encapsulation methods (reducing agents) for self-healing asphalt concrete.

Keywords:

alginate, encapsulation, modifier, restoration, self-healing, asphalt concrete.
