Abstract

 Grading of bitumen is performed based on performance and it depends on the maximum and minimum location temperatures values of implementation pavement and traffic load. The objective of present research was survey of applied bitumen based on PG, climatic and traffic conditions as a case study. Using environmental conditions and an experimental study on hot asphalt, Marshall, aggregate and base layer samples were carried out in current research. These tests included temperature of pavement, Coarse and Fine Aggregate Angularity, Sand Equivalent, Coarse and Fine Aggregate and Los Angeles test, Resistance, Softness, Breakage, Deformation, Specific Gravity, Moisture of fine aggregate, Density, Aggregate Grading, LL, PL, PI, Empty space of asphalt, Compaction, Thickness of asphalt, Thickness of base layer, Space filled with bitumen, Bitumen/mixed asphalt, Bitumen / asphalt without bitumen, Empty space asphalt, aggregates and aggregate filled of bitumen. Using ESRI ARC GIS 10.2 Software a performance grading map was depicted to the Iran. According to the highest and lowest available temperature ranges of the asphalt, the country was divided into different zones. The asphalt properties with light, medium and heavy traffic were obtained in full agreement with required standard specification of asphalt for roads with heavy, medium and light traffic loads wearing course in case study. Therefore, locally asphalt or bitumen applied can be used without the need of modification in all parts of case study Province.
