Abstract

The invention provides a processing technology for rock asphalt modified asphalt by adopting an oil grinding method. The processing technology comprises the following steps: (1) crushing, dehydratingand activating rock asphalt; (2) melting the rock asphalt treated by step (1) and matrix asphalt at low temperature of 140 DEG C to 149 DEG C, so as to obtain the rock asphalt modified asphalt; (3) cutting and grinding the rock asphalt modified asphalt prepared by step (2) at 140 DEG C to 149 DEG C until the fineness is -100 meshes or lower. A whole technological process of the rock asphalt modified asphalt is carried out under a low-temperature blending condition; the activity of the rock asphalt is preserved to the greatest extent when the rock asphalt is processed at low temperature and thecarbonization effect, caused by high temperature, on the asphalt matrix is reduced. The processing technology provided by the invention has the advantages of simple preparation technology and convenience for operation and the performance of the modified asphalt is good, so that the processing technology is suitable for being widely popularized.

Description

technical field

[0001] The invention relates to rock bitumen modified mixing technology, in particular to a rock bitumen modified bitumen oil grinding method processing technology. Background technique

[0002] Bitumen is a material commonly used in the preparation of paving and roofing materials. In the road-building and road-laying industries, it is a well-established and practical method to coat aggregate materials, such as sand, gravel, crushed stone, or mixtures thereof, with hot fluid bitumen and apply the coated material to the roadbed or The previously constructed road is laid in a uniform layer and rolled by a heavy-duty roller to compact the uniform layer to form a smooth-surfaced road.

[0003] The combination of bitumen and aggregate material such as sand, gravel, crushed stone or mixtures thereof is known as "asphalt concrete". Bitumen, also known as "asphalt binder," is usually a liquid binder that contains bitumen, resins, and oils. It can occur naturally, ...
