Abstract
The invention relates to a light-duty modified asphalt which is prepared from the following raw materials in parts by weight: 20-40 parts of petroleum resin, 20-40 parts of rubber process oil, 3-12 parts of thermoplastic styrene-butadiene rubber (SBS), 5-10 parts of low-density polyethylene (LDPE), 0.01 part of dioctyl phthalate (DOP) and 0.01-0.03 part of polyethylene wax. The light-duty modified asphalt is cheap; and according to the 70# matrix asphalt, the standard penetration degree is 60-80, the softening point is greater than 45 DEG C, the ductility (10 DEG C, 15 DEG C) is greater than 100CM, and the asphalt 135 DEG C kinetic viscosity is less than 3 Pa.s. The light-duty modified asphalt has lighter chroma (14-17) according to the standard chroma card, and belongs to light yellow; the color is light and is easy to change; and thus, the light-duty modified asphalt can be easily mixed with most colorants, and has bright discharge color. The road asphalt specifications clearly point out that the 135 DEG C rotary viscosity of the modified asphalt should be less than 3 Pa.s; and the 135 DEG C viscosity of the light-duty modified asphalt provided by the invention is 2.58 Pa.s, so the light-duty modified asphalt is easy for construction due to the lower viscosity.
