ReLIXER Archives

ReLIXER® is a specially formulated elixir of bio-based oils that rejuvenates aged bitumen when recycling and reusing high levels of reclaimed asphalt pavement (RAP) and/or reclaimed asphalt shingles (RAS) in mixes. Sripath’s ReLIXER is the leading asphalt rejuvenator or recycling agent on the market – trusted by customers worldwide and backed by peerless technical support from our in-country agent network. An asphalt rejuvenator is an additive that can restore the functional properties of aged asphalt binder, also known as bitumen. While the benefits of high-RAP mixes are many, there are physical limitations to using large amounts of RAP. Adding an asphalt rejuvenator can restore functional performance of aged asphalt and allow for higher RAP usage, up to 100% in some cases.

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 will look to offset the impact of stiffness compared to [...]

Pothole Pitfalls and How to Prevent Imperfections in Roadway Paving

New roadway infrastructure development is on the rise with market growth of 8.05% expected by 2032. This demand is due, in part, to the deteriorating condition of existing roadways. In fact, in the U.S. alone, 39% of roads are considered to be in poor or mediocre condition. The primary culprit behind substandard roadway conditions: potholes. Damage [...]

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 specifications. Typically, by using a blend from different fractionated particle [...]

Sustainability in Asphalt with Sripath Additives That Support a Reduced Carbon Footprint

Traditional methods and materials for roadway development may be here to stay, but the advent of sustainably produced additives that may support contractor and department of transportation goals to lower their carbon emissions are much newer to the industry. Newer still is the perspective that asphalt and bitumen additives can be produced with a lower carbon footprint, helping [...]
