The deterioration of physical and mechanical properties of bituminous materials that are attributable to the aging of bitumen is one of the major causes of reduction in service life of flexible pavements. Thermal-oxidation ...

Most highway agencies use the default values of the lane distribution factor (LDF) as suggested by their pavement design guidelines. However, the use of the default value of the LDF results in over- or underestimation of ...

Moisture damage in the bituminous layer is one of the major causes of deterioration in the functional and structural performance of the flexible pavements in the field. This will result in an increase in the maintenance ...

In this present study, bio-binder was made using the bio-oil obtained from rice straw and petroleum hard pitch to reduce the air pollution caused by the burning of waste rice straw in the field. The physical, rheological, ...
