In terms of structural issues and bearing capacity, if this asphalt layer is placed at a level of more than ten centimeters compared to the final surface, it has no load-bearing capacity and can be easily used to fill passive cracks if this asphalt layer is placed at a level of less than ten centimeters compared to the surface. to be final, it will find the burdensome conditions for which it is necessary to think of arrangements. In this research, an attempt has been made to separate the nature of these two types of asphalt sand from each other, their technical and regulatory criteria, and price analysis and payment methods from the road price list have been studied and evaluated.
