Use of X-Ray Fluorescence (XRF) to Determine Tire Rubber Content in Asphalt Binders 0-7168
Many Texas Department of Transportation (TxDOT) districts across the state use tire rubber (TR) in asphalt binders on chip seal projects. Traditionally, the test procedure that determines whether the appropriate amount of TR is in the binder has only been performed in the TxDOT Materials and Tests Division lab, requiring a long time to complete. Researchers at University of Texas Center for Transportation Research developed a portable X-Ray Fluorescence (XRF) device that can test for binder TR levels in minutes, allowing the testing to occur in the district labs and even in the field. District personnel are being provided with the device and trained on its use.

  • @majorrev8690
    @majorrev8690 9 днів тому

    The section of highway I frequently travel on had a surface prep featuring grooves perpendicular to the direction of travel, which allowed drainage to the shoulder and some additional traction, especially in a braking situation. A few years ago this section was resurfaced, with the grooves now being parallel to the direction of travel. They now hold water and I have personally narrowly escaped 4, maybe 5 if i wanna be picky, near misses from a small car hydroplaning while traveling at speed, as if they quickly yanked their steering wheel. We know they didn't. It had rained, it was not raining anymore but the water could not drain like it used to before the resurfacing. The resurfacing is very reflective too, almost as if the pavement was semi polished. This is very bad on evening drives after a rain where the sun is coming back out. With the water not draining, the semi shiny surface, you cannot see a thing! This is very dangerous. Yep, that semi polished surface is a heck of a lot more slick, esp in wet conditions. This particular stretch of highway Im talking about is one I know very well. Ive seen it grow from just asphalt with a large grass median for future expansion, to getting that expansion, to the community growth it spurred, etc. But now a days I can almost guarantee you and everyone above you on your org chart, that there is a wreck EVERYTIME it rains now. What where yall thinking? I wish I could see the minutes from those design reviews. It would probably be embarrassing to the dot i bet. I mean, what justification was used to go with this resurfacing? Did yall even do a study on the effects of such a change to drainage AND traction available from a shiny new surface? Yall messed up here. Bad.

    The real purpose is to invest into this toll to make billions and anyone that doesn’t like can leave. The better option is to A: build a transit train shuttle from Galveston island to the Conroe. and B: Build a stack Highway on I 45 that would allow 10 plus lanes each going North and South.

    Where is the analysis of the potential decrease in regional population due to increasingly hot and dry weather? Will all this traffic continue, if the region becomes uninhabitable during the very period when construction is contemplated? Please consider bolstering efforts to sequester heat-causing carbon from the atmosphere through improved soil health and regenerative agricultural practices that also cool the regional weather. The hydrology of the region must somehow be expanded, not depleted. Please consider doing something to enhance the capacity of the wetlands, not put them in jeopardy!

    We have enough cement, infrastructure, and roads all over the city already. By having a piece of what we originally are nature, we can continue to connect with nature in a deeper level and have a deep understanding of where we come from and how everything works. This area is perfect for understanding how our earth is changing and how climate change is affecting the planet that we live in. This is important because by learning more about it, we better understand how it affects all of us all living things on this earth. It has been proven that nature can help reduce stress and bring feelings of joy therefore, it is important to have such an attraction in the city of El Paso for its residence to enjoy. I strongly believe that a location like Rio Bosque wetlands can also bring tourist into our city, which is a benefit for other businesses. We need to speak up for those who cannot speak up for themselves, the innocent, the vulnerable; we are their voice they depends on us. We must protect the many species that inhabit Rio Bosque wetlands, otherwise you will be destroying many homes and many families of wildlife. Let’s not forget a lot of migrating birds stop there for water. Because we are in a desert, water is not easy to find. How would you feel if you were traveling along distance and had no water to drink ? think of that for a minute.. lot of these animals are sentient that means they feel and they know. This is also a great space for El Paso residents to get exercise, as it is El Paso does not have many attractions. This is one of the most beautiful attractions that one can enjoy living here. Please take into consideration all the lives that are going to be hurt by this both wildlife and human. As the selfish humans that we are, for once let’s think of other living beings instead of ourselves, the way we usually do. God bless, whoever is making this decision with the right decision, the ethical decision. We can help our planet and give back to it, protect it, take care of it and respect it, or we can continue to destroy the way we have been which has led us NO WHERE GOOD!
