**Aplication rates will vary depending on traffic volume, intended use, soil type, weather conditions, soil moisture levels and compaction. On-site testing is recommended to determined optimal application rates.
DX1000 – Lifespan Expectations
A DX1000
application typically last about one year. There are substantial variations to
this due to type of soil/aggregate that makes up the road, amount of traffic
shear; depth of dust, amount of dust that blows in from untreated areas, etc.
(recommend DirtGlue polymer application to soft shoulders and embankments
immediately adjacent to the DX1000 treated roadway to minimize contamination of
treated roadway surfaces).
Most dirt roads are hard packed base from long
term use with a layer of dust on the surface created by tire slippage (shear)
scuffing and wearing away at the surface of the hard packed base.
A brief discussion of each issue:
1) Aggregate made from softer rock break up from
traffic faster than harder rock therefore more dust sooner. Soils with high clay
content tend to absorb much of the DX1000, especially the first application thus
shortening the life span of the application or requiring higher initial
application rate to make up for the high initial absorbance.
2) Rubber tired traffic that just rolls over a
straight, level surface makes very low shear. Traffic that must accelerate or
decelerate due to hilly terrain creates much more shear due to tire slippage
during acceleration and deceleration. Traffic turning, stopping, backing, etc
creates large amounts of shear. More shear equals more dust which means shorter
treatment life or higher application rates.
3) Road surface material of such poor quality
that it becomes muddy during wet periods or road base that is of such poor
material that it cannot support traffic load and allows mud to ooze up through
the application from the pressure of the load will not be a good candidate for
DX1000 except during the dry season because the mud when it dries and became
pulverized by subsequent traffic will result in a dust layer covering a
perfectly good Dx1000 application.
4) The deeper the dust layer the more DX1000 that
will be required for adequate treatment. Sweeping or blading a heavy dust layer
off of the surface may allow for reduced applications rates.
5) The vacuum or draft from passing traffic may
pull dust from the soft shoulder along the side of the road and this dust
settles out on the treated driving surface of the roadway contaminating the
application and prematurely overwhelming the DX1000 treatment. A light
application of DirtGlue polymer to the sides of the roadway can mitigate this
problem.
6) Sometimes high winds can blow dust from a
substantial distance onto the treated road surface thus prematurely overwhelming
the treatment.
