The present application relates to the field of asphalt recycling, and specifically discloses a method for recycling asphalt pavement. The method includes the following steps: S1: milling and crushing the old asphalt pavement, and then recycling the old pavement asphalt material; S2: heating the old pavement asphalt material, adding aggregate and asphalt rejuvenating agent to prepare a mixture A; S3: taking SBS modified asphalt, with nano-TiO 2 / ACF material and additives are mixed to prepare mixture B; then mixture B is heated to 145-165 ° C, mixture A is added, and after stirring evenly, recycled asphalt material is prepared; S4: the recycled asphalt obtained in step S3 is prepared The asphalt pavement regeneration treatment is completed after the material is paved and compacted. The regeneration method of the present application is simple to operate, and the asphalt pavement laid with the recycled asphalt material has the properties of high temperature resistance, low temperature resistance, elasticity, skid resistance, fatigue resistance and aging resistance, and can adsorb and decompose the asphalt material in the production process. , Asphalt fumes generated during the paving process.

The invention relates to the field of equipment for ceramics, in particular to a ceramic bottom polishing machine and a using method thereof. A polishing disc is arranged on a machine frame, a transmission shaft is fixed to the middle of the rear side of the polishing disc, a dust sucking cover is matched with the lower portion of the polishing disc, and the transmission shaft is connected with a transmission device; the bottom of a sliding rod is fixedly welded to the middle of the upper end surface of the machine frame, the sliding rod is arranged at the front part of the polishing disc, and a clamping device is slidably connected to the sliding rod, and the clamping device moves to a proper position from the polishing disc on the sliding rod; the bottoms of the ceramics face towards the direction of the polishing disc and then are sequentially placed between a first clamping bracket and a second clamping bracket, and the clamping device can make certain sliding relative to the sliding rod; and then a motor is started to drive the polishing disc to rotate for polishing the bottoms of the ceramics. According to the ceramic bottom polishing machine and the using method thereof, the ceramic reversed-placing mode adopted by traditional ceramic bottom polishing is changed, displacements of the ceramics are avoided, and meanwhile the distance between the bottoms of the ceramics and the polishing disc can be finely adjusted during the polishing process, thereby improving controllability of polishing.
