The invention discloses an
asphalt warm-mixing foaming
system which is used for solving the problem of mixing hot
asphalt for high class highways. The
system mainly consists of a water storing device, a water feed device, an
asphalt foaming device and an
electric equipment control device, wherein the water storing device is connected with the water feed device which is connected with the asphalt foaming device; the
electric equipment control device is connected with the water storing device, the water feed device and the foaming device; an asphalt foaming
pipe in the asphalt foaming device is in a two-layer sleeve structure, wherein an outer casing
pipe is a
heat transfer oil heating casing
pipe, and an inner core pipe is a foam asphalt generating core pipe; splitter plates are arranged at an asphalt inlet part, and fixed
helical blades which are orthometric are arranged at the inner part of a pipe cavity of the foam asphalt generating core pipe;
water spray nozzles for foaming are symmetrically arranged. Through the adoption of the foaming
system, the hot asphalt and water are combined to enable the asphalt to generate foams, so that the stickiness of the asphalt is reduced, the temperature and the time for mixing the asphalt with aggregates are reduced and shortened, and the problems of energy dissipation and low construction efficiency are solved; at the same time, the environmental
pollution degree and the production cost are reduced, and the construction is facilitated. The system disclosed by the invention has the advantages of simple and practical structure, easy manufacture, simple control, accurate computation, strong compatibility and the like.
