Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits. The mechanism of WMA is to use some additives or technologies to reduce the viscosity of bitumen and to modify the rheological behavior of bituminous binders, and thus improve the workability of the mixture at lower temperature. In this study a paraffin wax based addit...

Based on the analysis of the mechanism and hazards of asphalt fume, by adding two fume suppressant Mg(OH)2 and Al(OH)3 and two viscosity reducers Sasobit and ROADBIT-BPL, the paper optimized the mixture ratio for road use, and prepared the environment-friendly fume-suppression asphalt, and then conducted the performance tests to identify the optimum dosage. The results show that: the fume amoun...

This study compares the rutting and cracking resistance fatigue parameters of crumb rubber (CR) modified warm asphalt binders, which were determined by viscoelastic continuum damage (VECD) theory. The effect combination CR modification Sasobit, a mix additive, was investigated. Performance + Sasobit compound compared with styrene-butadiene-styrene (SBS) modification. Newly developed rheological...

Recently, bitumen pavements have been widely used for road paving. Various scholars modified in paving to improve pavement performance, thus increasing the service life. In this study, Sasobit, XT-W3, and Evotherm were selected as warm-mix various investigations including conventional Brookfield rotational viscosity, dynamic shear rheology, Marshall stability, high-temperature rutting, water lo...

Research of different asphalt modifiers has been necessary for the attempt to construct durable roads with higher standards. Fischer Tropsch-paraffin wax (Sasobit) recently attracted considerable attention over polymer modification due its capacity lower energy requirements asphaltic mix construction. In this study, Sasobit was used recover performance as well workability 3 wt% linear low-densi...

The objective of this study is to develop a modified asphalt with excellent rheology and workability. Buton rock (BRA) composite warm mix (BCMWMA) was prepared, its rheological properties micromechanisms were investigated. Initially, (WMA) prepared using 3 wt% Sasobit, then four BCMWMA samples by blending 5 20 BRA (with intervals). Subsequently, the microscopic morphology modification mechanism...

In this paper, it has been attempted to evaluate the performance of asphalt overlays which were reinforced with geogrid, modified by sasobit and combination of them on rehabilitation of reflective cracking. The laboratory tests under dynamic loading in bending mode were conducted to investigate reflective cracking retardation compared to reference samples. The results illustrated that in a cert...

Sustainability and durability are the key requirements of pavement structure. asphalt structure involves utilization Warm Mix Asphalt (WMA) technologies with addition Reclaimed Pavement (RAP), where performance parameters like fatigue fracture resistance properties etc. Utilizing RAP content in mix increases mixing compaction temperature which may degrade asphalt. Hence, numerous studies have r...
