A byproduct of changes in bitumen quality is the trend for engineers to formulate asphalt mixes using a balanced mix design approach. This relatively new method accounts for variable bitumen specifications while prioritizing adherence to performance standards. Balanced mix design also allowed for incorporation of additives that can enhance the functional properties of a mix to improve performance outcomes. Rather than relying solely on binder or aggregate specifications to meet performance standards, all aspects of the mix (binder, aggregate, modifiers, and additives) are formulated to balance factors such as fatigue, rutting, and cracking characteristics.
Why You Should Use Recycled Asphalt Pavement
Why should you use Recycled Asphalt Pavement (RAP)? The simple answer: Save money while maintaining performance!! RAP reduces your need for virgin asphalt. RAO reduces the need for virgin aggregate. Save on your raw material costs. Conserve non-renewable resources. Reduce the amount of construction debris going into landfills!! The cost savings you realize will, of course, depend on the [...]
