Warm Mix Asphalt (WMA) is a set of technologies that uses additives to reduce binder viscosity and increase mixture workability, which provides complete coating aggregates at lower temperatures around 100 °C 130 °C. Organic wax or Sasobit one the can be used for this purpose. It reduces melting point wax, allows production asphalt mixes temperatures. This attempt proposes new relationships elas...

In this work, an aged asphalt was mixed with a new modified based on styrene–butadiene–styrene (SBS) in different proportions, and the warm mixing agent added to simulate fusion behaviour recycled fertilizer (reclaimed pavement, RAP) content. Low field nuclear magnetic resonance (LF-NMR), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR) were used as analytical techn...

In this study, different contents of Nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen to modify the physical, mechanical and rheological properties of warm mix asphalt (WMA). WMA is containing 2 wt.% of Sasobit (mixture of long-chain hydrocarbons). Various quality control tests have been carried out to characterize the modified bitumen and WMA. The rheo...

Abstract In order to explore the rheological properties of high content warm mix recycled asphalt binder, was added into prepare asphalt. The optimum regenerant and Sasobit REDUX determined by basic performance test temperature scanning test. chemical composition studied FITR. low crack resistance were analyzed DSR BBR tests, determined. results show that when is 10%, its recovers level base ca...

This study aimed to determine how various concentrations of warm mix asphalt (WMA) additives can affect the rheological and physical characteristics cement. Bitumen was modified by chemical additive PAWMA® with an addition ratio (0.2, 0.4, 0.6), while organic additives, Sasobit® Kaowax®, were added at (2, 4, 6%) weight bitumen. hardness, softness, temperature susceptibility, viscosity, elastic ...

As a kind of environmentally friendly material, crumb rubber modified asphalt is widely used in highway engineering to accelerate the consumption end-life tires. The objective this study investigate high-temperature rheological properties composite (CRCM) asphalt. In study, same content and different additives were added prepare CRCM asphalt, including CRCM-SBS, CRCM- Sasobit/BRF, CRCM-RARX. vi...

Obtaining warm asphalt concrete mixes is an urgent task in the road industry, as it allows solving environmental, technological and economic problems of preparing laying concrete. One such technologies production using organic additives based on synthetic waxes, which until recently were presented market exclusively with imported products. In current political situation, relevance development i...
