Modified Asphalt Binder

Poor storage stability is a key problem restricting the rapid development and wide application of rubber-modified asphalt binder, and activation of rubber has shown good prospects to solve this problem. In this study, two activation methods, coating by polyamide 6 and grafting by acrylamide, were introduced to treat crumb rubber. Then the activated rubber was added to base asphalt binder to prepare modified asphalt binder. The chemical structure and morphology of rubber powder before and after activation and of asphalt binder before and after modification were characterized by Fourier transformation infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The conventional and rheological properties and storage stability were analyzed to reveal the influence of activation method on the performance of asphalt binder. The results showed that after being activated, the surface of the rubber is loose and rough. A chemical reaction did not occur during activation by polyamide but occurred during activation by acrylamide. The activation of the rubber effectively improved the high- and low-temperature performance, and the softening difference decreased by 79.8%. This is because the interaction between rubber and asphalt binder was enhanced through activation of rubber, and grafting activation had better effect due to the chemical reaction between the basic amide groups of acrylamide and acid groups of asphalt binder.

Abstract Mixtures of varying ratios of either channel black or a soft carbon black with whiting, lithopone, or clay show additive physical properties. Mixtures of soft carbon with zinc oxide also show additive properties, while mixtures of channel black and zinc oxide show poorer resistance to abrasion, higher modulus, and higher tensile strength than would be shown by purely additive mixtures. The explanation of these results appears to be found in the chemical reaction between the basic zinc oxide and the acidic compounds in the rubber or on the black. These results have been applied to the formulation of a solid-tire stock which will give a better resistance to abrasion and blow-out when using a soft black than when using a channel black.

The hollow-triangle PA6 composite shaped fiber produced by high-speed spinning with semi-dull polyamide 6 chips was designed and developed in our lab. Both the morphological structure and the rebound resilience of the fiber were observed and analyzed. Meanwhile, the weak acid, neutral and disperse dyes were applied to in the dyeing test. The results showed that the hollow-triangle fiber had a high degree of profile and good bulkiness. Furthermore, the immediate elastic recovery and total elastic recovery rate of the fiber were large. When stretched by 5%, the immediate elastic deformation of this fiber was 86.4% and its elastic recover rate was up to 100%, which is obviously better than that of the general PA6 fiber. Besides, the dyeing ability of the hollow-triangle PA6 fiber was nearly the same as that of the general one when it was dyed with different dyes under the normal technical conditions.
