Abstract

The invention discloses a regenerated OGFC (Open-graded Friction Courses) mixed material and a preparation method thereof. The mixed material comprises cellulose, hyperviscosity modified asphalt, new mineral aggregate, mineral powder and an OGFC old material. The preparation method comprises the following steps: respectively heating the OGFC old material, new mineral aggregate and hyperviscosity modified asphalt; then, mixing the heated OGFC old material and the new mineral aggregate with cellulose; then, adding the heated hyperviscosity modified asphalt into the mixture and mixing; then, adding the mineral powder, continuously mixing to form a regenerated OGFC mixed material; and finally, carrying out a Xielunbao asphalt leakage loss experiment and performance index test on the regenerated OGFC mixed material. The preparation method of the regenerated OGFC mixed material provided by the invention is simple to operate and accurate in result, and the potential value of the OGFC old material is fully utilized and the OGFC old material is reduced to the regenerated OGFC mixed material, so that the cost of OGFC is lowered.

Description

technical field

[0001] The invention belongs to the technical field of road material preparation, and relates to a preparation method of an OGFC mixture, in particular to a regenerated OGFC mixture and a preparation method thereof. Background technique

[0002] Open Graded Friction Course (OGFC for short) refers to paving with asphalt mixture with large void ratio, which can quickly drain rainwater from the inside of the road surface, and has anti-skid, noise reduction, anti-glare, The road paving material that seeps into one body is generally used as the upper layer or the upper layer and the middle layer of the drainage pavement. With the application and popularization of drainage pavement, the use of OGFC as the most important surface material of drainage pavement has increased sharply.

[0003] However, during the use of the drainage pavement, the gaps in the OGFC will be blocked by solid particles such as accumulated dust and tire rubber particles. After long-term use...
