  • 1.  Waste engine oil in bituminous pavement

    Posted 08-16-2019 10:17 AM

    I'm starting my research regarding use of waste engine oil in bituminous pavement. My question is what are the things I should consider while doing research on this topic? And how waste engine oil will help us to solve problems related to bituminous pavement?

    It will be your most kindness by helping me regarding this topic.

    Hi and thank you for your question and work.  I'm a structural engineer but am deeply involved in sustainability issues. Of particular interest in the Circular Economy (ISO TC 323) or closing the loop on the waste stream and putting waste to beneficial, long-term use.


    With regard to something like repurposing waste oils two things come to mind: the economics of oil reuse and, as I'm sure others will suggest, fixing the toxics (heavy metals, benzine, etc.) in the oil.  Thus far the economics of materials reuse with the burden of quality assurance and pollution controls has been a big road block to materials reuse. Of especial interest in quantifying and monetizing in some tangible fashion, community health to offset the burdens.  If you can crack that nut – you are a hero.

    Thank you for your question and work. I am a retired highway engineer and remember several attempts to squeeze more life from used oil.  As noted by C. Michael Donoghue, PE, public health concerns crop up when the used oil is used for dust reduction and other uses also.  Used oil is currently collected and processed to be used in several ways including as heating oil for drying asphalt aggregate. However, again public health is paramount and restrictions are in place and keep getting more scrutiny.
    Your research could take a different approach by forecasting the use and predicted volumes of oil consumption after electric powered cars and trucks assume predominance.
    Some questions that I have are:
    • How can this resource reinvent itself?
    • When will the majority of cars and light trucks convert to electric power?
    • Will the oil industry transition to suppling battery exotic metals?  

    Whatever your choice of study, good luck and enjoy the trip.

    Thank you.
    Which oil is good for tests as well as for bituminous pavement real or synthetic one? What are the tests required in this topic which I should consider? I'm fresh regarding this topic, so from where I should start work? It's my kind request to you that you will help me.

    Hello Aashiq,

    I echo the sentiments of others - that you are looking at ways to reuse waste oil. The use of the oil for drying aggregates seems to be a good idea, while within the environmental boundaries. However, I would be uncomfortable with using the oil in asphalt mixes as 1) it does not help in binding of aggregates and b) might dilute the binding quality of the asphalt used. Now as for the type of oil - synthetic or real - do consider the use it is being up to. What is the intent and the expected goal.

    Good luck!

    This is not recommended due to the detergents in the motor oil which can hinder the bond of the asphalt to the aggregates.
