In the photo, from
left to right, Dr. Natalia, Mikhail Kalinin, the Director of ABZ-1 OJSC
(business unit of ABZ-1 Group of Companies), produced the mixes at their
asphalt plant, and Kirill Melnik, Head of the
Laboratory. Everyone is very happy to have a successful demonstration
project that took place on fantastic weather day. The last time that St.
Petersburg felt 15 ⁰C on October 13th was 120 years ago!
acknowledges that the stakes are very high. Traditional wisdom dictates
that to resist studded tires large particles aggregates must be used.
Meanwhile tradition wisdom also dictates that to reduce noise small
particle size mixes should be used combined with more open graded
made towards improving noise reduction may affect durability regardless how
good Prall test results appear to indicate. The
combination RARX with high quality abrasives has never been tried
before! “In a year or two
we will be able to ascertain the cost benefit of these innovative solutions
No noise evaluating
CPX tests have been done yet. However, Dr. Natalia’s expression after
driving over the section was: “Drove over the overlay by car
at a speed of 110 kilometers per hour. Noise from the wheels significantly
I guess you can be
the judge of the effectiveness of these RARX-SMA and RARX-THINGAP in noise
reduction. In the video below, they are the blacker surface on the left
lane that appears around the 34th second into the video (turn up the sound
to listen, you will listen to the noise difference between regular and the
new RARX sections).
