WesTrack refers to an experimental road test facility constructed in Nevada under a contract awarded by the Federal Highway Administration (FHWA). The project, entitled "Accelerated Field Test of Performance-Related Specifications for Hot-Mix Asphalt Construction" (Contract No. DTFH61-94-C-00004), has two primary objectives:
To continue the development of performance-related specifications (PRS) for hot-mix asphalt construction by evaluating the impact on performance of deviations in materials and construction properties (e.g., asphalt content, air void content, and aggregate gradation) from design values in a large scale, accelerated field test.
To provide early field verification of the SHRP SUPERPAVE(TM) Level III mix design procedures. Westcom.com
Nevada has two main freeways that connect to Utah, and Utah is a hotbed for this technology, with government support. West Trac technology has been around, the idea is to pull longer loads and get efficiency. The automation speed long haul cargo by by 2 or 3 times. The measure to look at is joules/$gdp, what is the gain by speeding up larger loads?
But Las Vegas, and Reno even, have another idea, moving lots of people at higher speeds. And the Disneyland effect of Johnny Cabs along the strip.
