Problems solved by technology

However, the plant-mixed cold recycling technology of foamed asphalt is very dependent on construction machinery. At present, the output of plant-mixed cold recycling equipment commonly used in China is generally 200-220t / h, which seriously does not match the construction capacity and affects the overall construction progress.

Abstract

The invention discloses a plant-mixing cold-recycling foamed bituminous mixture production system, relating to the technical field of road paving devices. The plant-mixing cold-recycling foamed bituminous mixture production system comprises a stabilized soil mixing plant and a bitumen foaming device, wherein a bitumen jet pipe of the bitumen foaming device is communicated with a stirring device of the stabilized soil mixing plant, the bitumen foaming device comprises a new bitumen heating tank and a bitumen foaming pipe, the bitumen foaming pipe is of a double-layer sleeve pipe structure, and an inner-layer core pipe of the bitumen foaming pipe is sequentially provided with a self-spinning turbulator, a cross butt-jointing blade and a radial guide pipe from the inlet end to the outlet end. The plant-mixing cold-recycling foamed bituminous mixture production system is transformed by the existing stabilized soil mixing plant directly, the investment cost is low, and the stabilized soil mixing plant can achieve multiple purposes.

Description

technical field [0001] The invention relates to the technical field of road paving devices. Background technique [0002] Factory-mixed foam asphalt cold recycling technology refers to the old asphalt pavement after milling, digging, recycling, crushing and screening, adding a certain proportion of asphalt, new aggregate, cement and water, mixing, paving and rolling and other processes to form a pavement structure layer that meets the performance requirements. Foamed asphalt cold recycling technology can achieve energy saving and emission reduction, recycling of waste resources, protection of ecological environment, etc., and can also reduce engineering costs. The popularization and application of this technology will generate huge economic and social benefits. Since foamed asphalt is foamed by violently expanding asphalt through physical methods, the key to the application of foamed asphalt cold recycling technology largely depends on the foaming effect of asphalt. The mai...
