Asphalt Tonnage Calculator, Surface Paving and Haul Roads

Caterpillar Performance Handbook, edition 50, Paving Products. None of these is offered as a standard. Each is the density Cat assumed to build one of its own tables, and the book does not say which mix any of them is. 145 sits under the cold planer chart on p. 10-2, "as referenced on AsphaltPavement.org, the website of NAPA". 155 is the assumed condition on both compactor tables, pp. 10-20 and 10-22. They are 6.9% apart. Cat's paver production chart on p. 10-12 prints no density at all, but working its own cells backwards gives about 146 lb/ft³, which is why 145 is the default here: it is the density Cat's own paving chart is built on. On p. 10-22 Cat prints the metric figures as "kg/cm³", a unit misprint for kg/m³, and reads 2486 where 155 lb/ft³ converts to 2483, the figure p. 10-20 prints. This page works in lb/ft³ and converts exactly, so those 3 kg/m³ never reach the answer.

Caterpillar Performance Handbook, edition 50, p. 10-12, "Asphalt Paving Charts". Cat: "These charts will assist you when trying to match plant output with paving speeds. Keep in mind when using these charts, it will be at 100% efficiency. If you know efficiency, multiply T.P. hour × efficiency." This page does not look numbers up in the chart; it works the arithmetic the chart is built on (width × speed × 60 min × compacted thickness × density ÷ 2,000 lb), so it answers for any width, speed and thickness, and the chart is kept here to check it against. Every cell agrees with that arithmetic at about 146 lb/ft³ to within 2%, except two marked *, which are misprints: the 2 in. and 3 in. charts are each the 1 in. chart multiplied up, and those two cells are not. The 2 in. cell at 20 ft/min and 7 ft should read 102, not 176, and the 3 in. cell at 20 ft/min and 12 ft should read 264, not 284.
