Laboratory Evaluation of the Residue of Rubber-Modified Emulsified Asphalt

Abstract: Emulsified asphalt has been widely used in various surface treatment methods such as chip seal for low-volume road preservation. Using modified emulsified asphalt made it possible to use chip seal technology on medium- and even high-volume traffic pavements. The main objective of the study is to quantify the residue characteristics of rubber-modified emulsified asphalt and to assess the effectiveness of using crumb rubber to modify emulsified asphalt binder. The four emulsified asphalt residues used the distillation procedure. Then, the rheology characteristics of emulsified asphalt residue were evaluated. The Fourier transform infrared spectroscopy (FTIR) test analyzed the chemical change of emulsified asphalt during the aging procedure. The results indicate that the evaporation method cannot remove all the water in emulsified asphalt. The mass change during the rolling thin film oven (RTFO) process only represented the component change of emulsified asphalt binder residue. Both the high-temperature and low-temperature performance grade of the two emulsified asphalt binders with rubber were lower. The original asphalt binder adopted to emulsification had a crucial influence on the performance of emulsified asphalt. The rubber modification enhanced the property of the emulsified asphalt binder at low temperatures, and the improvement effect was enhanced as the rubber content in the emulsified asphalt was raised. The C=O band was more effective in quantifying the aging condition of the residue. The findings of this study may further advance the emulsified asphalt technology in pavement construction and maintenance.

Kansas Department of Transportation 2014 chip seal manual : [technical summary].

Abstract: A chip seal is a very effective thin surface treatment process used by maintenance managers to preserve existing asphalt pavements. The Kansas Department of Transportation (KDOT) 2014 Chip Seal Manual is a guide that provides guidelines, background and general information for the design, construction, and inspection of chip seals. This manual is intended for use by KDOT field engineers, laboratory personnel, construction inspectors, and contractor’s estimators, supervisors, operators, and workers to provide procedures for the design of chip seals. The information, recommendations and best practices provided in this manual may refer to either: (1) learning the overall chip seal operation; (2) learning about the workings, maintenance, calibration and proper operation of equipment used in chip sealing; or (3) learning chip seal design procedures. This manual consists of seven chapters. Chapter 1 is the introduction. Chapter 2 is about selection of chip seal. Chapter 3 discusses the materials for chip seal and the design process. Chapter 4 discusses surface preparation prior to chip sealing. Chapter 5 describes equipment inspection and calibration. Chapter 6 discusses the actual application process. Chapter 7 underlines the areas of concern during construction process.

The Monroe, Michigan Chip Seal Case Study: An Evaluation of Multiple Chip Seals’ Cold Weather Field Performance

Abstract: The purpose of the Monroe Chip Seal Case Study was to evaluate chip seal performance for multiple test sections comprised with different asphalt emulsion – aggregate type combinations with emphasis on aggregate retention, especially during winter months. Different emulsions and aggregates were desired to be evaluated to determine if there was an optimum combination for performance in this climate over the course of one winter. Specific comparisons of interest in this project included: (1.) Neat (non-oil) emulsions versus emulsions with low oil additives, ( 2.) Modified emulsions with latex styrene butadiene rubber (SBR) versus modified emulsions with styrene butadiene styrene (SBS) and ( 3.) Limestone aggregate retention versus crushed gravel aggregate retention. Aggregate retention was measured through imaging analysis. Photographs were taken at identical locations monthly between September 2009 and April 2010. The change in aggregate coverage was measured over time by converting the photographs into black and white binary images. The binary images allowed for the calculation of aggregate coverage. Major findings of the research include that adding 1.0% #2 fuel oil to an anionic high float emulsion improved performance (aggregate retention) over emulsions without oil. Anionic limestone chip seals outperformed anionic gravel chip seals. No appreciable difference between limestone and gravel cationic chip seals was observed. There was no significant difference between latex modified and tyrene butadiene styrene (SBS) modified chip seals for gravel seals. Limestone seals with latex modified emulsion performed slightly better than SBS modified chip seals.
