Applications for FGD By-Product Gypsum
With the rapid growth of the City of Phoenix, islands of non-paved streets developed causing dust and  bottlenecks that had to be paved.  These were low-volume
streets with not willing property owners to pay for the cost of construction.  Alternate...

Applying the Pavement Management Concept
Pavement Management is a broadly based process which encompasses the set of all activities required to provide and maintain pavements.  Several important
concepts are discussed including the level of influence concept, planning and prediction in...

Asphalt-Rubber Binder Laboratory Performance
Three experimental test roads containing asphalt-rubber interlayers were constructed.   Test pavements were designed as statistical experiments such that future
performance analysis could be obtained.  Precondition surveys were conducted prior to rehabilitation...

Evaluation of Asphalt-Rubber Interlayers
This report presents the field performance results of three asphalt-rubber interlayer test roads in terms of the effectiveness of the interlayer at reducing the rate of
reflection cracking.  Several variables were included in the field experiments: concentration...

Evaluation of Asphalt-Rubber Membrane Field Performance
This report presents a record of asphalt-rubber membrane field performance in Texas.  An evaluation of performance is presented for forty-five separate projects in
thirteen state highway districts.  Approximately 850 lane miles of highway are represented by materials constructed as stress absorbing...

Evaluation of Rubber-Asphalt Mixture Used as A Stress Relieving Inner Layer
This report deals with a demonstration study on SH 36 in Washington County which monitored the performance of the asphalt-rubber inner layer when in place and
discusses the construction techniques used...

FAA Mixture Design Procedure for Asphalt-Rubber Concrete
The primary objectives of this research were to define the laboratory conditions necessary for producing a mixture design of asphalt–rubber concrete.  Because
laboratory tests used to evaluate the properties of asphalt-rubber are not defined sufficiently...

Hot Asphalt-Rubber Seal Coat as A Stress-Relieving Interlay
This is the last stage of Task B of the project plan.  The project was completed May 26, 1978, but the hot rubber-asphalt seal (stress relieving interlayer) was completed
in July, 1977.  Traffic has used...

Laboratory Behavior, Performance Prediction, and Cost-Effectiveness of Asphalt-Rubber Concrete in Airport Pavements
A research project was performed which indicated that ground tire rubber added to asphalt concrete significantly improves the material parameters which are generally
used to evaluate an asphalt concrete mix for use in pavement.  The study also indicated...

Laboratory Evaluation of Crumb Rubber Modified Mixtures Designed Using TXDOT Mix Design Method
The Texas DOT has developed a mixture design procedure for crumb rubber modified asphalt concrete mixtures.  Eight CRM mixtures were designed using this
procedure.  Four wet process mixtures, four dry process mixtures and one control mix were considered for...

Laboratory Evaluation of Crumb-Rubber Modified (CRM) Binders and Mixtures
CRM binders were fabricated in the laboratory and evaluated according to ten different binder tests.  Some of the test procedures routinely used for CRM binders were
determined to have no apparent relationship to mixture...

Mechanistic Evaluation of Selected Asphalt Additives
Highway engineering is a field which requires the judicious use of materials manufactured by nature.  Naturally occurring soils serve as the foundation for highway
pavements.  Some serve faithfully and well.  Others cause problems at every opportunity.  Nature’s products are used in pavement bases...

Pavement Inventory - Smaller Local Government Case Study
There are approximately 3,100 counties and 16,000 cities in the United States that spend almost $10 billion a year to maintain and improve a 3 million mile system of
roads and streets.  This is a massive commitment of public funds...

Performance Prediction and Cost-Effectiveness of Asphalt-Rubber Concrete in Airport Pavements
This paper reports on the promising results of a research study conducted to investigate the feasibility of using asphalt-rubber concrete, which contains ground and
recycled tire rubber, as a surface material for airfield pavements at municipal airports.  This research indicated that asphalt-rubber...

Physical Properties of Asphalt-Rubber Binder
A study was performed to determine how the physical properties studied were the low-, intermediate-, and high temperature rheological properties, measured with the
bending beam rheometer, dynamic shear rheometer, and rotational viscometer, respectively.  The physical properties...
