The Influence of Thickness on Density of an I-2 Bituminous Mix

Report No: 78-R47

Published in 1978

About the report:

From this very limited study, it was concluded that (1) even when the road cross section was distorted, the contractor did an excellent job of controlling the average application rate; (2) the percent compaction, while acceptably high, did not increase as the rate of application increased; (3) about 3 vibratory roller passes were equivalent to about 5 static passes; and (4) riding quality appeared to be a function of thickness, with the 165 lb yd².- section having the lowest roughness value.
