Problems solved by technology
[0005] The purpose of the present invention is to provide a kind of road project asphalt laying pretreatment process, to solve the problem in the prior art in the process of transshipment or reclaiming of asphalt in the above-mentioned background technology, stone or other hard materials are often easily mixed into the asphalt raw material. Impurities in the asphalt will affect the purity of the asphalt, which will easily lead to changes in the viscosity or performance of the asphalt after crushing, which will affect the use effect of the asphalt, and due to the characteristics of the asphalt itself, hard impurities such as stones mixed into the asphalt are often difficult to be removed. unmanageable problem

The invention discloses a highway engineering asphalt laying pretreatment process which is characterized by comprising the following steps: step 1, firstly, opening a sealing mechanism at the top of a treatment box (1) in asphalt laying pretreatment equipment, and putting asphalt needing impurity removal treatment into a centrifugal net cylinder (10) from a feeding hole (6); step 2, closing a sealing mechanism at the top to enable the heating tank (3) to form a sealed environment, starting the annular heating tank (3), and rapidly and continuously heating the heating tank (3); 3, a driving motor (9) is started to drive a rotating rod (8) and a centrifugal net barrel (10) to rotate rapidly, so that molten asphalt in the centrifugal net barrel (10) is rapidly centrifugally thrown out and flows out from an outflow hole (4) in the bottom of a heating tank (3); 4, the cooling mechanism rapidly cools the falling asphalt, so that the asphalt is rapidly cooled and solidified; and step 5, thoroughly crushing the solidified asphalt by a crushing mechanism in the asphalt laying pretreatment equipment.
Description
technical field [0001] The invention relates to the technical field of asphalt pretreatment, in particular to a road engineering asphalt laying pretreatment process. Background technique [0002] In today's road construction, asphalt pavement is mostly used, which refers to various types of pavements paved with road asphalt materials mixed with mineral materials; asphalt binder improves the resistance of pavement aggregates to road damage and natural factors. Therefore, asphalt pavement is one of the most widely used advanced pavements in road construction. [0003] In the prior art, in the process of transferring or reclaiming the asphalt, the raw materials of asphalt are often easily mixed with stones or other hard impurities, which affects the purity of the asphalt, and easily leads to changes in the viscosity or performance of the crushed asphalt, which affects the asphalt. Due to the characteristics of asphalt itself, hard impurities such as stones mixed into asphalt a...
