404-LVT
404-LVT was developed for use in low volume traffic applications as an alternative to chip
sealing and microsurfacing to provide longer service life between treatments, better economy, and
motorist satisfaction. It is a 1-inch thick asphalt overlay that corrects minor surface distresses,
provides increase to pavement strength, enhances ride comfort, and improves road profile and driver
safety. (Note: A variable-depth intermediate course is recommended where profile or crown are
excessive.) 404-LVT can be furnished as either a hot mix asphalt or warm mix asphalt product. A
404-LVT pavement surface is smooth, eliminates dust, is free of loose stone chips, and is quiet and
completely reusable into new asphalt pavement.
404-LVT has been designed to be rich in asphalt binder, fine-textured, and includes a
minimum of 50% of the virgin fine aggregate to be natural sand to facilitate mix density, flexibility,
and resilience. These are necessary properties for ensuring longevity and successful mix
performance on low volume roadways where oxidation and cracking are the primary pavement
distresses. Since 404-LVT is a recipe mix it should only be used for roads and parking facilities
where heavy, slow moving trucks do not frequent. Do not use in conditions known to be “high
stress” pavement areas.
In March of 2023, the University of Akron presented the results of an ORIL (Ohio’s Research Initiative for Locals) project titled Optimizing the Performance of Item 404 - Low Volume Traffic Mixes. Select the
