Due to the amount of heavy traffic over the years, the asphalt drives at Invista in Chattanooga, TN had taken a lot of abuse. The roads were failing in places and needing to be replaced. The company put together an engineered plan that involved pulverizing the old asphalt, treating the soil with cement, and then paving the areas with roller compacted concrete. The processes that Phaltless would be taking care of would be to pulverize the old asphalt and then treating the soil with cement. The roller compacted concrete was to be installed by others.
To achieve the desired grade, a portion of the existing materiel was hauled off site. Once the desired grade was achieved, the job called for cement to be mixed with the existing materials, with water, at a rate of 6% by weight at twelve (12) inches thick. The raw cement dust was spread over the existing materials. A water truck was then hooked up to the reclaimer machine that mixed all of the materials together at a depth of twelve (12) inches.
Below are photos that show Phaltless in action.

Your sconed last photo shows a lip at the gutter and a protruding watermain. This would indicate that the asphalt shown is just the base and not the final surface layer. This could very well be an HL8 layer consisting of larger aggregates used for stabilization. A finer HL3 finished surface will likely follow next spring.
