Video: Balanced Mix Design Benchmarking Strategies
Balanced mix design, or BMD, focuses on engineering asphalt mixes that meet a variety of performance specifications. Going beyond traditional volumetric requirements, BMD requires thorough benchmarking strategies to produce satisfactory results. Benchmarking starts with clearly defined performance standards. These include setting guidelines for resistance to cracking, rutting, [...]
Video: 6 Ways to Cut Carbon Emissions in Asphalt Paving
TRANSCRIPT: Reducing carbon emissions in asphalt paving is an essential component of roadway infrastructure development and planning. Government agencies and municipalities, contractors, and producers are all exploring measurable ways to shrink the carbon footprint of roadway projects. Here are six of current trends in asphalt paving technology [...]
VIDEO: How to Process Reclaimed Asphalt Pavement (RAP)
Efforts to improve sustainability in asphalt paving have made reclaimed asphalt pavement, or RAP, a top priority. Using RAP reduces the need for virgin aggregate and binder, cutting costs and environmental impact. But high-performing RAP mixes require proper processing and the right rejuvenator. Here’s how the nine-step [...]
VIDEO: 8 Step Framework for Balanced Mix Design in Asphalt
TRANSCRIPT: Asphalt mix design engineers are facing challenges in balancing requirements for roadway durability, sustainability, and cost. Using balanced mix design, or BMD, shifts the focus from volumetric properties to performance testing. This can help engineers optimize resistance to rutting, cracking, aging, and [...]
VIDEO: Why Bitumen Quality Matters in Asphalt Roadway Production
TRANSCRIPT: As global demand for roads grows, so does the importance of the material that holds them together: bitumen. However, once a consistent, locally sourced byproduct of oil refining, bitumen quality has become increasingly unpredictable. Why? Because modern refineries now prioritize extracting other [...]
Video: What happens to old asphalt? Can it be recycled?
TRANSCRIPT: What makes roads age? What happens to aged roadway materials once they require replacement? Is there a way to recycle these materials into new roads? Let's check it out. Over time, roads age. Sun, heat, ice, rain, and heavy traffic eventually lead to rutting, cracking and [...]
Video: What are the Environmental Concerns and Safety Considerations for Using an Effective Asphalt Rejuvenator?
TRANSCRIPT FROM VIDEO: The safety and environmental impact of an asphalt recycling agent should be considered when selecting a rejuvenator or recycling agent. An effective rejuvenator will not only meet performance specifications but also consider worker safety and exposure issues and help reduce carbon emissions. These considerations [...]
Video: How Should RAP Be Managed at a Mix Plant?
TRANSCRIPT FROM VIDEO: To use high amounts of Reclaimed Asphalt Pavement along with an effective rejuvenator, plant and quality managers need to make changes to how they process their materials. While RAP has historically been perceived as a waste product, plants should treat it with the same [...]
Video: Can the Use of High-RAP Mixes with an Effective Rejuvenator Save Costs?
TRANSCRIPT FROM VIDEO: Overall mix cost is a critical component when designing a balanced mix that also meets performance and sustainability requirements. Importantly, high-RAP mixes have been shown to demonstrate cost savings in research conducted by the National Asphalt Pavement Association. According to NAPA data, using RAP [...]
Video: How Do High-RAP Mixes Dosed with Rejuvenators Age?
TRANSCRIPT FROM VIDEO: Balanced mix design that incorporates Reclaimed Asphalt Pavement dosed with a rejuvenator should consider adherence to performance properties both now and many years after wear and weathering. Testing should include an evaluation of how the aging process impacts these mixes to ensure durability and [...]
Video: High-RAP Mix Case Study: Lab Test of 100% RAP Dosed with ReLIXER
TRANSCRIPT FROM VIDEO: While high-RAP mixes include any mix with more than 25% Reclaimed Asphalt Pavement, some departments of transportation are looking to push the envelope on RAP usage. When using an effective rejuvenator, RAP usage of up to 100% is possible while maintaining performance specifications. A [...]
Video: How can an ideal asphalt rejuvenator be evaluated?
TRANSCRIPT FROM VIDEO: As Reclaimed Asphalt Pavement becomes more commonplace in roadway development, standards are high for rejuvenators. To evaluate the efficacy of a particular recycling agent, multiple factors must be considered. Effective asphalt rejuvenators should restore the properties of aged bitumen, aiding with functional characteristics such [...]
Video: How Have Asphalt Recycling Agents Evolved?
TRANSCRIPT FROM VIDEO: When using Reclaimed Asphalt Pavement in mixes was first introduced, the common belief was that the only modification needed was to soften the binder before adding RAP to a mix. However, research has demonstrated that while viscosity is an important property to consider, additional [...]
Video: Why are Asphalt Rejuvenators Necessary for Reclaimed Asphalt Pavement (RAP) Mixes?
TRANSCRIPT FROM VIDEO: Reclaimed Asphalt Pavement is sourced from older, weathered, and worn roadway surfaces. Because of this, the materials in the RAP, particularly the bitumen, age and lose some of their chemical and physical properties. As the binder oxidizes over time, the material can become brittle. [...]
Video: How is asphalt rejuvenator dosage determined based on bitumen data?
TRANSCRIPT FROM VIDEO: The approach used depends on the specifications adopted for liquid binders in a given jurisdiction, country, or region. Some locales will set softening point and penetration specs, some will use binder viscosity specs, and yet others may rely on performance grade specs. In all [...]
Video: How are Reclaimed Asphalt Pavement (RAP) mixes evaluated for balanced mix design?
TRANSCRIPT FROM VIDEO: There are several approaches to evaluating RAP in balanced mix design. Balanced mix design considers the functional characteristics of the mix and seeks a compromise between competing properties in order to meet the required specifications for roadway performance. For example, a balanced mix design [...]
Video: What are the steps for processing Reclaimed Asphalt Pavement (RAP) for a mix?
TRANSCRIPT FROM VIDEO: Asphalt mixes incorporating RAP should be evaluated for key performance specifications. To do this, samples from the fractionated RAP stockpiles are taken to a lab for analysis. Determining the amount of RAP viable in a balanced mix design will depend on the established mix [...]
Video: How is reclaimed asphalt pavement (RAP) processed for reuse? ( Cloned )
TRANSCRIPT FROM VIDEO: To recycle RAP into new roadway surfaces as an eco-friendly alternative, the material must be processed into a more uniform product. First, the material is screened to remove foreign matter. Then, the remaining aggregate is crushed into smaller particles, often broken down from larger [...]
Video: Where does reclaimed asphalt pavement (RAP) come from?
TRANSCRIPT FROM VIDEO: Reclaimed Asphalt Pavement, or RAP, comes from the material removed during a roadway resurfacing. Most RAP is produced by milling the top two inches of the road’s wearing course to prepare the surface for new paving material installation or, in the case of full-depth [...]
Video: What is the case for using high RAP in mixes?
TRANSCRIPT OF VIDEO: There are two main drivers for considering using high RAP, or reclaimed asphalt pavement, in mixes: economic and environmental. Economically, agencies need to know that using high amounts of RAP can and will provide cost savings over traditional use of virgin materials. Research by [...]
Video: Understanding Asphalt Rejuvenation: Benefits, Types, and Applications
What is asphalt rejuvenation? Asphalt rejuvenation is the process of using a recycling agent to restore the functional performance and balance the physical properties of aged binder found in reclaimed asphalt pavement (RAP). Effective asphalt rejuvenation with a proper recycling agent results in a bitumen that meets [...]
