Plant for the production and distribution of bituminous conglomerates and operating method of the plant, wherein the plant is provided with a dryer having a first portion and of a second portion, which are connected to each other in series one after the other.

The present utility model pertains to the technical field of equipment for producing asphalt concrete (AC) or hot mix asphalt concrete (HMAC), and relates more particularly to an improvement to mobile asphalt plants provided with side protectors. Proposed are protective screens for the areas which should be avoided by operators and others, where high temperatures and noise levels prevail. The protectors are installed in the area where virgin aggregate arriving from the metering system is transferred to the drying/heating system, where the intake temperature of the metered material is high and elements such as the conveyor belt can cause injury to operators. The other area to be isolated is the place where the burner of the plant carries out the process of combustion.

The present disclosure provides an improved system and process for the production of Hot Mix Asphalt containing High Recycle/Reclaimed Asphalt. Unlike conventional processing systems, the presently disclosed system utilizes a combination of dryer design and cyclone and wet scrubber technology to remove dust, particulate matter and oil residue from hot gas emissions produced during the process and recycles it back into the system.

Procedure and plant for the production of tempered bituminous mixtures with reclaimed asphalt pavement (RAP) comprises: a) Provision of RAP having a granulometry comprised between 0 and a maximum diameter; b) Processing said RAP to obtain at least two RAP fractions (one fine, another coarse); c) Subjection of predetermined quantities of said RAP fractions to a process of mixing and heating by hot gas flow such that the heating times of each fraction are adapted to the granulometry thereof, the temperature of the mixture at the end of the step being comprised between 90 C. and 120 C.; d) Blending the mixture with a predetermined quantity of bituminous emulsion supplied at a temperature comprised between 60 C. and 80 C. The temperature of the final mixture will be between 90 and 110 C.

A system for controlling the production of an asphalt mix. The preferred system comprises an asphaltic material source, an asphaltic material sensor, a liquid asphalt cement source, a liquid asphalt cement meter, and a controller. The asphaltic material sensor communicates the amount of asphaltic material liquid asphalt cement and the amount of asphaltic material moisture contained in the amount of asphaltic material to the controller, the liquid asphalt cement meter communicates the amount of liquid asphalt cement provided by the liquid asphalt cement source to the controller, and the controller controls the amount of asphaltic material provided by the asphaltic material source and the amount of the liquid asphalt cement provided by the liquid asphalt cement source. A method comprising controlling the amount of asphaltic material and the amount of liquid asphalt cement provided to the asphalt mix substantially continuously and substantially in real time.

The present invention relates to an asphalt composition containing an asphalt, a polyester resin, and a crosslinked rubber.
