Aging in the Field Has an Effect on the Initial Voids in the Polymer Modified Bitumen Mixture, So This Research Is Used to Evaluate the Effects of It.
In addition to its use in road construction, bitumen is also widely used in roofing applications.
Bitumen roofing materials, often referred to as "built-up roofs," are made by layering bitumen-saturated felt or fiberglass mats with bitumen coatings.
These roofs are durable, waterproof, and resistant to UV radiation, making them ideal for protecting buildings from the elements.
Bitumen roofing materials come in a variety of forms, including shingles, rolls, and membranes, providing options for different types of buildings and climates.
Another important application of bitumen is in waterproofing.
Bitumen is used as a waterproofing agent in a wide range of products, including sealants, mastics, and coatings.

During the service life, weather conditions and repeated loading will degrade the durability of the asphalt mixture, and then lead to some irreversible pavement distress.
In order to meet these demands, the increasing volume of highway traffic is constantly increasing the demand for the quality and durability of the asphalt mixture.
Therefore, the deterioration of the asphalt pavement caused by stress and repeated stress is considered as cavitation.
As a result, the asphalt binder plays an important role in many aspects of road performance.
On the other hand, recent comments indicate that permanent deterioration has become one of the most important mechanisms of pavement stress in asphalt pavements.
Polymer Modified Bitumen Features
Since asphalt binder is a material that is highly affected by aging, researchers are constantly searching for technical asphalt binders to meet additional requirements in various fields such.
The aging of asphalt mixture continues through their service life, at a lower rate compared to that occurring during production and construction.
At present, aging is considered one of the other pavement problems, it increases the pavement stiffness and affects pavement recycling.
The aging of asphalt mixture occurs through production and construction throughout the service life of asphalt pavement.
A previous study has confirmed that the aging of asphalt binder is the main cause of durability failure of asphalt pavement.
The modified asphalt mixture is usually applied to change the formation stage and enhance the engineering properties of asphalt mixtures.

The use of kaolinite clay with bitumen is proven to enhance the layers of wearing course via a new calculation of the volume of the mixture.
The use of recycled brick powder as an additive in the asphalt mixture can lead to the attainment of better mechanical properties than the samples with limestone filler.
Using amorphous carbon powder as a bitumen modifier can improve the rutting resistance of asphalt binder and mixture substantially.
Applying filler in hot mix asphalt contributes to improving fatigue performance, rutting behavior, and moisture damage resistance.
To predict the changes in asphalt mixtures’ properties, this paper purposed to enhance the performance of long-term aging on the service life of asphalt mixture.

The asphalt mixture tests of Superpave were conducted, including resilient modulus, dynamic creep, and indirect tensile tests when subjected to long-term aging conditions.
Based on the results of these tests, it can be concluded that the addition of soft clay has a significant effect on reducing the tensile strength of the mixture.
other effects are improving the high-temperature performance of asphalt from rutting and fatigue dissipated energy perspective.
The method is used in the process of accelerated aging and some tests were used to determine the rutting and fatigue of the aged mixture.
