What Is the Performance of the Asphalt?
The performance of the asphalt mastic is the portion of the asphalt mixture responsible for binding the aggregate together.
It decreases with time due to the cumulative impact of environmental variables such as sunlight, oxygen, and water.
In this article, we are going to give a report on whether aging and the asphalt fatigue process.
It does not encourage satisfying the long-term performance criteria of long-life asphalt pavement, which is unfavorable to meeting such standards.
In this study, five different types of base asphalt mastic and styrene-butadiene-styrene (SBS) modified asphalt mastic were generated by altering the filler-to-asphalt ratio to one of the following values: 0.6, 0.8, 1.0, 1.2, and 1.4.
Specifications for Asphalt Paving
The performance of the asphalt mastic, which serves as the binding component in asphalt pavement, will gradually decrease throughout the length of a long-life asphalt pavement's service life, which can vary from 40 to 60 years.
This will happen as a result of the weather's aging over time.
It will result in an irrevocable decrease in performance and a shorter service life.
As a result, it is critical to conduct a long-term study on the effect of aging on the functionality of asphalt mastic.
A variety of factors can contribute to the aging of asphalt mastic while asphalt pavement is in use.

According to the fatigue life-filler-asphalt ratio correlation, the optimal filler-asphalt ratio for base asphalt and the optimal filler-asphalt ratio for SBS-modified asphalt are 1.0 and 1.2, respectively.
After some time, the base asphalt mastic will be more sensitive to strain level than the SBS-modified asphalt mastic. Base asphalt mastic fatigue life increases under low strain load and declines under high strain load.
In contrast, throughout the strain load range of 0.1% to 10%, the fatigue life of SBS-modified asphalt mastic rapidly decreases as the aging degree increases.
