Shell GTL Asphalt Additives
Shell GTL Saraphalt is a versatile asphalt additive polymerised from natural gas via Fischer–Tropsch synthesis, suitable for high quality warm mix asphalt applications on roads, highways, bridges and airport runways.
Improved Asphalt Performance
Better workability
With the reduction of asphalt binders’ viscosity at elevated temperatures, the process of storage transfer to production plant, mixing with other components, placement and compaction work at construction site are improved.
Improve stability
With enhanced Tensile Strength Ratio (TSR) of asphalt binders, it exceeds the minimum requirement of ASTMD4867 (Standard Test Method for Effect of Moisture on Asphalt Concrete Paving Mixtures).
Higher durability
As a result of improved rutting, oxidation aging, fatigue and fuel resistance which enhance hardness and reduction of temperature susceptibility of the binders, the asphalt is made more durable against poor weather conditions, high traffic loads and damage contact with fuel.
Tested for application on highway and bridge construction
Evaluated and certified by AASHTO’s (American Association of State Highway and Transportation Officials) National Transportation Product Evaluation Program (NTPEP) for Warm Mix Asphalt (WMA) application.
Lower Emissions, Energy Consumption & Improves Working Conditions
Improved working conditions and energy consumption
The reduction of emissions from the asphalt mixture with less fumes, aerosols, and high heat exposure helps to improve workers’ health and working conditions. The processing at lower temperatures also enables the extension of paving season into the colder and more temperate season of the year, enabling additional time to complete paving projects.
Lower CO₂ emissions and energy consumption
Producing asphalt mixtures with special properties to enable paving at a lower temperature, Warm Mix Asphalt (WMA) with Shell GTL Saraphalt offers reduction in CO2 emissions and lesser energy consumption.
