Gilsonite or Asphaltum is a natural, resinous hydrocarbon which in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. Gilsonite for road paving is a common usage of this substance. Gilsonite’s unique properties make a road that is less susceptible to high-temperature and deformation performance issues. Gilsonite can be added directly at the hot mix plant without additional equipment.
Gilsonite Increase Performance of Asphalt Roads
Gilsonite enhance the quality and perfomance of the roads because:
Safe and environmental friendly—Asphalt roads offer high skid resistance and provide high contrast in color between asphalt pavement and road markers, giving drivers better road visibility in any weather condition. Unharmed by ice and snow chemicals, asphalt’s dark color also reduces glare and melts ice and snow more rapidly than other pavement types. Open-graded asphalt, a special type of road surface, can minimize splash and spray during rainstorms and reduce crashes and fatalities on highways. Asphalt pavement materials also eliminate potentially dangerous and expensive pavement blowups. Asphalt is 100% recyclable and the most recycled product in America. The asphalt industry reuses and recycles 100 million tons of asphalt pavement a year, saving taxpayers over $2 billion annually. Asphalt also requires 20% less energy to produce and construct than other pavement materials. Post-consumer waste such as used tires and shingles can also be reused in new asphalt pavement, reducing landfill space and conserving natural resources.
Smooth and quiet—Asphalt pavements provide a more uniform surface unmatched by other pavements. Smooth roads are safer because rough, uneven surfaces increase driver fatigue and diminish control. Smooth asphalt roads also reduce rolling resistance (the friction between tires and pavement), which means better fuel economy and reduced carbon dioxide emissions. Smooth roads allow superior contact with vehicle tires for a safer (and more enjoyable) ride. Roadway noise is a distraction in your car and at home. Asphalt roads can reduce highway noise by as much as seven decibels. For scale of reference, reducing noise by just three decibels is the equivalent to doubling the distance from the source of the noise to the listener. Asphalt roads also reduce the need for costly and unsightly sound barriers, often exceeding $2 million per mile. In order to provide and maintain smoother roads across the country, they need to be constructed and engineered correctly at the beginning construction stages. In order to do that, the asphalt roads need to be strong, durable and resistant to rutting and cracking, resulting in an extended asphalt pavement life.
Cost-Effective and durable—Smooth roads with gilsonite aren’t just safer, they also save money. Reduced wear and tear on vehicles due to fewer bumps in the road brings down vehicle operating costs. Also, increasing a roadway’s smoothness by 25% extends its lifespan—upwards of 10 percent—which saves taxpayers money. Asphalt roads can be built more quickly and cost-effectively than other pavements as well, and they can be designed as a Perpetual Pavement that needs only periodic maintenance to remain in good shape indefinitely. Asphalt pavements have long lives. All asphalt pavements have a bridging action and are flexible, which means they can withstand occasional overloads without serious damage. They can be designed to suit any conditions of traffic, soils, and materials. Asphalt only needs periodic maintenance to remain in good shape indefinitely. Modified polymer additives can increase binder performance under certain extreme conditions. However, SBS polymers cost more than twice as many as Gilsonite. A more cost-effective solution is to combine Gilsonite and SBS polymers to achieve the desired grade. Overall, less fuel consumption helps the environment and driver’s fuel budgets, leading to a greener and more cost-effective form of infrastructure. Since the United States has over 2.5 million miles of paved best asphalt roads, just a slight change in each person’s fuel economy can make a huge difference. It is proved that gilsonite-modified bitumen significantly increases the service life of asphalt pavement. This is good news for companies looking to cut costs.
Gilsonite Decrease Thickness of Asphalt Roads
Glance Pitch and Graliamite are natural hydrocarbon materials with a high softening point known as asphalt. They are sold in their native state after extraction. They are added to asphalt to harden and strengthen and decrease its thickness it because they are compatible with asphalt. Asphalt generally has a thicker layer of 25-40 mm. Gilsonite is used around the world as asphalt modifier in the form of a dry bulk solid granular powder. Gilsonite has many advantageous for asphalt pavements such as: increases its stability, decrease thickness, make it resistant to deformation (e.g: rutting and shoving), prevent water penetration and It makes it more capable of withstanding loads. Adding Gilsonite to asphalt increases the adhesion of aggregates to asphalt. It is also makes the pavements harder and stronger.
Gilsonite Prevent to Grow Plants in Asphalt Roads
The study of asphalt properties has been done to improve the pavement characteristics. It is shown that gilsonite prevent to grow plants in asphalt roads and Asphalt properties are manipulated to achieve properties such as good wear, corrosion resistance, fatigue and cracking resistance at low temperatures, adhesion strength, viscosity and pour point. Groove resistance is the resistance of asphalt against wheel groove pressure. Adhesion strength is the maximum tolerance of the joint and the tank against splitting, but is not limited to the space of the bond and aggregate. People believe that Gilsonite makes pavements prone to heat cracking by reducing pavements’ low temperature properties and prevent the growing of the plants. Adding melted Gilsonite to hot asphalt will reduce penetration and increase viscosity of the asphalt binder. It is also being mixed with aggregate before mixing with asphalt adhesive.
