A kind of preparation method and equipment of asphalt mixture prefabricated drainage splayed groove

Abstract

The invention relates to a method for preparing a prefabricated splayed trough of an asphalt mixture, comprising the following steps: step 1: preparing raw materials for the prefabricated splayed trough; step 2: stirring the raw materials to obtain an asphalt mixture; step 3: mixing the asphalt The material is loaded into the test mold; step 4: compaction; step 5: the asphalt mixture prefabricated drainage splayed groove is formed; step 6: demoulding; step 7: maintenance; The invention also provides the equipment for the preparation method of the asphalt mixture prefabricated drainage splayed groove. The beneficial effects of the present invention are as follows: the damage to the drain tank in severe cold weather is reduced, a large amount of financial and material resources are saved for the later maintenance, and the deicing salt has a strong anti-corrosion effect; the replacement is simple and convenient, and it is convenient for the later maintenance; the equipment The cost is low, the structure is simple and compact, the loading method is simple, and the operation is easy, which not only reduces the cost but also improves the working efficiency.

Description

technical field [0001] The invention relates to the field of a prefabricated asphalt mixture splayed trough, and in particular provides a preparation method and equipment for a prefabricated asphalt splayed trough. Background technique [0002] During the service of highway engineering, water is a very important destructive factor. It often causes serious diseases such as subgrade erosion, road surface muddying, and mud pumping, which affects highway traffic capacity and road driving safety. Therefore, the importance of road drainage is becoming more and more important. The bigger it is, the water encroachment problem of the subgrade should be paid close attention to, so as to ensure the smooth drainage of the subgrade, so as to maintain the overall continuous stability. In foreign countries, in addition to setting up a complete pavement surface drainage system, the pavement drainage problem is also studied from the selection of pavement materials, material combination desig...
