Abstract

The invention discloses a bituminous pavement hot-in-place recycling paving device. The bituminous pavement hot-in-place recycling paving device comprises a vehicle body. A material receiving hopper is arranged at the front end of the vehicle body and connected with a material receiving box through a first scraper chain. A stirring paddle is arranged in the material receiving box. A double-layer paving device is arranged at the tail of the vehicle body and comprises a front material divider, a front ironing plate, a rear material divider and a rear ironing plate. The material receiving box is connected with the rear material divider through a second scraper chain. A heating plate is arranged at the bottom of the vehicle body. The vehicle body is provided with a combustion furnace, a hot air outlet of the combustion furnace is connected with the heating plate through a hot air conveying pipeline, and the hot air conveying pipeline is provided with a circulation draught fan. According to the bituminous pavement hot-in-place recycling paving device, upper face layers and lower face layers of fresh materials and reworked materials can be paved and constructed at the same time, a lower bearing layer of the bituminous pavement can be preheated, the bonding quality between the layers of the bituminous pavement is guaranteed, hot connection of transverse and longitudinal construction work lines can be achieved, and the paving quality of the bituminous pavement is greatly improved.

Description

technical field [0001] The invention relates to an in-situ thermal regeneration unit for asphalt pavement, in particular to a paving device used for the last process of in-situ thermal regeneration of asphalt pavement. Background technique [0002] Asphalt pavement hot-in-place recycling utilizes the pre-order equipment of the unit to heat the asphalt pavement, loosen it, and remix it, and the recycled asphalt material falls on the ground to form a silo. Due to certain specific pavement requirements, the construction process may be adjusted at any time, either involving the overlaying process, or involving the issue of the grading of recycled materials. At present, there is still a lack of relatively complete equipment to meet the needs of various road construction techniques. Contents of the invention [0003] Based on the above-mentioned technical problems, the present invention provides an in-situ thermal regeneration paving device for asphalt pavement. [0004] The t...
