A Study of Flexural Fatigue Behavior of Asphalt-Rubber Mixes
The objective of this study is to evaluate the fatigue behavior of crumb-rubber modified asphalt.  The research involved flexural fatigue testing of beams made with hot-
mix asphalt rubber using the wet process where the crumb rubber reacted with the asphalt at high temperature.  Two types of asphalt-rubber were...

Asphalt-Rubber Hot Mix PCCP Overlay
An asphalt-rubber project was constructed on US-75 south of Topeka near Carbondale in August 1990.  The project mixes and thickness were constructed as indicated
in Figure 1.  Four tests section, two with asphalt-rubber and overlay.  J.C Shears, Inc. of the Emporia Division was the prime...

Cold In-Place Asphalt Pavement Recycling
Thermal cracking of asphalt pavement permits water to deteriorate the pavement and subgrade.  The resulting rough riding surface has been repaired by various
methods.  The approach of cold, in-place recycling and related testing...

Crumb Rubber Use in Hot Bituminous Pavements
Based on the results of our test sections and the results of the TTI study, KDOT decided not to construct any more SAM or SAMI test sections, but to continue literature
reviews on asphalt rubber.  KDOT then decided to construct several asphalt rubber...

Development of a Crumb Rubber Modified (CRM) Asphalt Concrete Mix Design
The objective of this project was to develop an asphalt mix design method incorporating crumb rubber and using the “wet” or “dry” method of producing Crumb Rubber
Modified Asphalt (CRM).  Several resurfacing projects...

Heater Scarification and Asphalt-Rubber-SAMI - Marion County - Final Report
The prime objective of this experimental project was to evaluate a surface absorbing membrane interlayer (SAMI) supplied and applied by Sahuaro Petroleum and
Asphalt Co.  The SAMI was constructed by applying an asphalt-rubber mix over a heater-scarified bituminous...

Prevention of Reflective Cracking in Flexible Pavements - Osage County - Final Report
A comparison of the transverse and longitudinal cracking within the test and control sections are shown in Figures 3 and 4, respectively.  As may be noted these crack
surveys were continued until Oct. 5, 1981.  Because of extensive cracking...

Structural Layer Coefficients for Crumb Rubber-Modified Asphalt Concrete Mixtures
Structural layer coefficients for crumb rubber-modified (CRM) asphalt concrete mixtures were developed from the back-calculated moduli values using the falling weight
deflectometer (FWD) test results on in-situ pavements.  Several test sections of recently built crumb rubber-modified pavements...

Use of Rubber in Asphalt Pavements – Kansas Experience
From 1990 to 1992 a total of eight rubber hot bituminous mix projects were constructed on the Kansas DOT highway system.  Of the eight projects constructed, four
have been dry, and four have been...
