The primary goal of the multiple layers of a pavement structure is to transmit and distribute traffic loads to the subgrade.

In this article, we are going to discuss how a geosynthetic can help with rutting in the asphalt mix.
Rutting is one type of pavement distress that can impair the performance of a road's pavement.
Geosynthetics are a type of synthetic material that is used to improve pavement rutting resistance.
Numerous studies on the use of various geosynthetic materials in pavement structures have been conducted by various researchers.
One of the procedures is to use a reinforcing material in asphalt pavements.
The results of some studies on the use of geosynthetics in flexible pavements as reinforcement against permanent deformation will be presented and discussed in this paper (rutting).
The pavement structure is vulnerable to a variety of stresses over the course of its service life.
Permanent deformation is one of the most serious problems that can occur when the pavement structure is involved (rutting).
Numerous studies have been conducted in order to find ways to prevent the rutting phenomenon from degrading pavement quality.
As a response to such distress, both traditional and contemporary approaches have been used.
One of the latter methods is to reinforce pavement structures with geosynthetics.
Numerous studies on asphalt concrete reinforcement are involved in the prevention of reflection cracking, and the use of geosynthetic materials as a reinforcing means in the pavement structure, primarily in road bases and embankments, is well investigated.
However, very little research has been conducted on the impact of reinforced asphalt concrete on the development of plastic and shear strains in asphalt concrete.
The purpose of this paper is to review some of the reported effects of geosynthetics on rutting in pavement structures.
To create flexible pavements, subbase, base, and surface courses are typically layered beneath a prepared roadbed.
Surface courses, also known as asphalt concrete, are a type of material made by compacting a mixture of bitumen, filler, and varying amounts of crushed rock, gravel, sand, and crushed stone.
Only after compacting will it have the required mechanical and physical properties.
Asphalt concrete can have three different physical states under different environmental conditions: plastic, viscoelastic, and elastic.
Rheology, a science that studies the fluidity of materials, provides the most detailed and accurate description of the asphalt concrete process.
Over the course of its lifespan in pavement structures, asphalt concrete is susceptible to a variety of distresses, the most common of which is fatigue cracking, rutting, and thermal cracking.
