Organic montmorillonite (OMMT) was obtained by reacting montmorillonite (MMT) with the surfactant cetyltrimethyl ammonium bromide (CTAB). The crystalline phases of MMT and OMMT were characterized by microscopic performance analysis using an X-ray diffractometer (XRD) and scanning electron microscope (SEM). The effects of rubber, attapulgite, columnar diatomite, and disk diatomite on the technological and rheological properties of OMMT-modified asphalt were studied using a dynamic shear rheometer, and the low-temperature properties were determined from their creep characteristics by a bending b...
