ENGINEERING PROPERTIES OF FIRST GENERATION PLASTICIZED SULFUR BINDERS AND LOW TEMPERATURE FRACTURE EVALUATION OF PLASTICIZED SULFUR PAVING MIXTURES

摘要: The low temperature fracture potential, fatigue and deformation characteristics of first generation plasticized sulfur binders in paving mixtures are discussed. Fracture mechanics techniques were used the characterization these materials. Recommendations, based on properties materials, for improvement engineering behavior second presented. Plasticized promising new materials; however, sensitivity is a problem that must be overcome before can cold climates or regions susceptible to rapid drops. Rheological testing has illustrated need consider this design applications. parameters defined discussed paper recommended as criteria development with improved properties.
