Another Look at Chemkrete
The purpose of the study was to investigate the effects of curing time and air void content on asphalt paving mixtures containing Chemkrete. One goal of the study was to determine whether the rapid aging of the product in the early stages is temporary to insure that continued hardening of the binder does not eventually produce excessively brittle mixtures. Different dosages of Chemkrete, aging periods and air void contents were evaluated using different asphalt aggregate mixtures. Laboratory tests and literature reviews indicated that the Chemkrete slows after about 20 days but does not appear to cease even at 90 days. Two field test pavements were constructed. Samples were subjected to long-term conditioning at high temperatures similar to summer pavement temperatures. Tensile strength, stiffness, stability and water susceptibility of roadway cores and laboratory molded samples were quantified. Extracted asphalt cements were tested for viscosity, penetration and softening point.
