Subroto, Sigit (2012) Modified Marshall characteristics of a dense-graded asphalt emulsion mix.
Full text not available from this repository.Abstract
Growth in the use of aspalt emulsions was relatively slow, and limited by the type of asphalt emulsions available and a lack of knowledge as to how they should be used. Continuing development of new types and graded of asphalt emulsion, coupled with improved construction equipment and practices now give a broad range of choices, with which virtually any roadway requirement can be met. Judicious selection and use of an appropriate asphalt emulsion can yield significant economic benefits. This thesis describes an investigation of the characteristics of an asphalt emulsion mix comprising a dense graded aggregate and a slow-setting cationic emulsion. The Marshall procedure was modified to evaluate the strength and deformation characteristics, of the mix; samples were tested in the dra condition at 35 o C. The influence of curing period on these two parameters was also assessed. Preliminary tests showed that the aggregate and emulsion were compatible and indicated a suitable premix water content. Tests indicated that there is an optimum compaction water content for maximum modified Marshall stability, and this paramater is a function of curingperiod. Measurements of strength and deformation made on specimens prepared at various asphalt emulsion contents indicated the following trends: - Modified Marshall stability decreases with increase in residual asphalt content; - Dry density decrease with increase in residual asphalt content; - The modified Marshall flow generally decreases to minimum value with increase in residual asphalt content; - At any residual asphalt content modified Marshall stability, Marshall quotient, and dry density generally increase with increase in curing time.
