Influence of Waste Engine Oil on Asphalt Mixtures
The results from the research reported in this paper indicated that the incorporation of waste engine oil into HMAwith RAP may offset the increase of stiffness caused by aged binder in RAP. The...
Effects of Used Engine Oil as Plasticizer in Asphalt Mix
As such, asphalt is progressively taking innovative undertakings. In order to minimize waste and hazards in used engine oil (UEO) as an additive plasticizer to the existing conventional...
Application of Design-Expert Response Surface Methodology
From the surface response in terms of penetration, ductility, softening point, glass transition temperature, and mass-loss percentage, the optimum waste engine oil-based rejuvenator had 5% plasticizer, 6.33% antiaging agent, and 7.3% fusogen.
Polyphosphoric acid and plasticizer modified asphalt
The machines used in the preparation of the modified asphalts were a high shear mixer and a digital constant temperature heating plate. Existing research shows that a plasticizer modified asphalt with 3.0 wt% plasticizer content has excellent low temperature crack resistance [44], [45], [46]. Thus, the plasticizer content was selected as 3 wt
Effect of used motor oil as a rejuvenator on crumb rubber
To obtain a modified binder blend with more enhanced intermediate- and low-temperature rheological properties, used motor oil (UMO) was introduced to the crumb rubber-modified asphalt (CRMA) binder. The enhanced high- and intermediate-temperature rheological properties of the modified binders were investigated using a temperature sweep test.
- How does a plasticizer affect the asphalt?
- The plasticizer physically modifies the base asphalt first, and subsequently interacts with it chemically through PPA. Accordingly, the modification effect of the plasticizer and PPA on the base asphalt involves both physical and chemical reactions.
- What happens if you add oil to asphalt?
- When you add oil to asphalt you are changing the mix ratio for that specific spot. This causes the asphalt where the oil has been sitting to become very soft, so soft you can sometimes dig the asphalt up with your finger nail. Once this happens all it takes is rain or snow to wear away the asphalt until you are left with a hole. (pictured).
- Is engine oil good for asphalt?
- The inclusion of waste engine oil decreased optimum asphalt content, and reduced rut resistance. Meanwhile, it may also have limited improvements on fatigue resistance of the mixtures. Content may be subject to copyright. ... There are several types of rejuvenators commercially available.
- Can waste engine oil be used as a base oil?
- In this paper, waste engine oil was used as the base oil to produce a competent rejuvenator for the recycled asphalt mixture based on the Design-Expert surface response method.
- Does the incorporation of waste engine oil into HMA with rap reduce stiffness?
- The results from the research reported in this paper indicated that the incorporation of waste engine oil into HMAwith RAP may offset the increase of stiffness caused by aged binder in RAP. The inclusion of waste engine oil decreased optimum asphalt content, and reduced rut resistance.
- Does asphalt rejuvenator increase moisture resistance and low-temperature cracking resistance?
- The mixture test results showed that the rejuvenator effectively increased the moisture resistance and low-temperature cracking resistance of aged asphalt mixture, which yielded comparable mixture properties with virgin asphalt mixtures.
