Book Description
This study evaluated and compared the effectiveness of polymer-modified asphalt mixes in improving the performance of the roadway in relation to rutting and cracking as compared to our standard mixes without modified binders. The addition of various polymers used in this study did not enhance the rut resistance potential of the mix, however the addition of the polymer did reduce the amount of transverse and longitudinal cracking to some extent.

Book Description
This report covers the pre-construction, construction and the first evaluation following construction at the following locations: I-25, Colorado Boulevard; I-25, Pueblo; Highway 85, Santa Fe Avenue; and I-70, Flagler. An additional project has been added that will be constructed during the 1992 construction season. This project is located on Brighton Boulevard between I-70 and Sand Creek. This project will contain a section with Type I polymer, a section with Type III polymer and also a section with no binder.

Book Description
This work describes the characterization of aged polymer modified bitumens to evaluate their potential for recycling. A tri-block co-polymer modified binder was selected and characterized using standard bitumen qualification techniques, i.e., the Superpave PG protocol. We developed a procedure to characterize the relative concentration of polymer in asphalt cements by gel permeation chromatography. Infrared spectrographic, thermogravimetric and rheological techniques were used to identify changes in the binder components as a result of aging. A correlation between field aging time and simulated aging by PAV was developed; PAV with humidity proved to be the best prediction. A comparison was established between the field aged materials and a series of lab aged binders. All binders were characterized with respect to their composition and rheological properties. In general, residual polymer was detected using gel permeation chromatography analysis except when extensive oxidative age hardening of the binder had occurred. Recycling of this material will require additives to restore the desired rheological properties to the binder blend.

Book Description
This literature in review investigates improving the temperature susceptibility properties of asphalt cement concrete on highways. The review is separated into six specific topics: polymer chemistry, asphalt cement chemistry, test methods, polymer modified asphalt cements, & specifications & field test sections. Key polymer properties that influence thermal & viscoelastic properties are molecular weight (MW) & distribution, architecture, & chemistry. Most polymers used n paving applications generally have a narrow MW distribution for any given product; MWs for individual products were not reported.

Book Description
A dozen papers from a June 1992 symposium in Louisville, Kentucky review the current use of organic polymers dispersed in water and formulated to add to portland cement. One sets out the status of ASTM's forthcoming specification and test methods. Others discuss such aspects as solid grade acrylic c

Book Description
Mortar and concrete made with portland cement has been a popular construction material in the world for the past 170 years or more. However, cement mortar and concrete have some disadvantages such as delayed hardening, low tensile strength, large drying shrinkage and low chemical resistance. To reduce these disadvantages, polymers have been utilized as an additive. Polymer-modified or polymer cement mortar (PCM) and concrete (PCC) are the materials which are made by partially replacing the cement hydrate binders of conventional cement mortar or concrete, with polymers. This book deals with the principles of polymer modification for cement composites, the process technology, properties and applications of the polymer-modified mortar and concrete, and special polymer-modified systems such as M DF cement, antiwashout underwater concrete, polymer-ferrocement, and artificial I wood. The polymeric admixtures or cement modifiers include latexes or emulsions, redispersible polymer powders, water-soluble polymers, liquid resins and monomers. This book describes the current knowledge and information of polymer-modified mortars and concretes, and discusses or reviews the following items in detail: 1. Principles of polymer modification for cement composites. 2. Process technology of polymer-modified mortars and concretes. 3. Properties of polymer-modified mortars and concretes. 4. Applications of polymer-modified mortars and concretes. 5. Special polymer-modified systems such as MDF cements, antiwashout underwater concretes, polymer-ferrocements, and artificial woods.
