Abstract:

Research was conducted in 1980 using Additive 5990 to prevent

reflective cracking in asphalt cement concrete when placed over

portland cement concrete. Test sections were placed with 08, 3%,

68, and 9% Additive 5990 by weight of asphalt cement at mix temperatures

between 375OF and 415°F with AC-5 and AC-10 grade asphalt

cement. Also, sections using AC-5 and AC-10 were constructed with

the normal mix temperature (not to exceed 330°F). One section was

placed using AC-20 mixed at the normal mix temperature.

It was concluded that the Additive 5990 did not prevent reflective

cracking on this project.
