Definitions

  • the present patent has for object a mobile mixer to be used in train for cold recycling asphalt concrete roadways.
  • the innovation finds particular even if not exclusive application in a mobile train to operate in situ in the road paving/repaving by also using recyclable material obtained by road scarification of the pre-existing road paving (art commonly known as "stabilisation").
  • the in situ road directly road
  • repaving known art provides the mixing and preparation of the components on the road itself after having carried out the milling (scarification) of the road paving for a certain depth (some centimetres), by means of a first front milling self-propelled machine, known as scarifier machine, which provides for milling the material upstream by a milling machine discharging it downstream on another towed machine, with eventual addition of new grit (for example by a grit spreader operating in front of the train), for the correction of the granulometric curves, and addition of binding materials with mixing action before the laying on road.
  • scarifier machine first front milling self-propelled machine
  • the work is started from the scarifier machine which scarifies (mills) the road paving for a certain depth transforming the road pavement in granular form (broken asphalt) , discharging it in a downstream line (grit line or broken asphalt continuous cumulus or continuous heap) where the heap shaper-meter adjusts it.
  • the corrective grit is spread by a grit spreader upstream of the scarifying machine, directly on the road pavement to be scarified, so that an even mixing virgin material or rejuvenant material with scarfied (milled material), by means of the same action of the milling cutters is obtained.
  • the train of machines which substantially concern the mixing therefore downstream of the scarifier machine, which generally operates separately, subsequently provides in the front-end, a self-propelled loader that conveys the broken material previously prepared in grit heap-line to a towed mixer machine which substantially concerns this invention, through a proportioning hopper, from which through a suitable ponderal dosage, it is discharged into the mixer.
  • the towed mixing machine mixes the materials introducing the hot or cold bituminous binder into a mixer, by a pump connected to the aggregates feeding system in order to add the binder necessary for the mixing by picking it up from a suitable binder material tank integrated with the train (asphalt recycling travelplant with cold planer).
  • the mixer or mixing machine or blending machine is made up of a container having a double rotor with blades.
  • one or more direct flame burners for the binder (bitumen) eventual heating are provided, and the mixed material is discharged while still hot, that is with the mixed bitumen not yet solidified, in the form of a heap line (grit line), from the rear mouth of the mixer,
  • the following machine in the train provides for spreading the material on the road by spreader.
  • additional water tank to the binder tank may be provided for cement mixture.
  • the same train can perform stabilisations with cement or with other binders (generally cold) such as for example bituminous mixtures in solution with solvents or in emulsion with water.
  • binders generally cold
  • the mixing unit includes a mixer group or unit (equipped/able with a water or volumetrically proportioned bituminous binders spraying device), of the "Trough” type with a pair of horizontal or lightly tilted shafts, longitudinally placed parallel to one another endowed with oppositely rotating mixing blades.
  • a road paving cold recycle train is provided, the train being for the collection in continuous of bulk material in a grit line along the feather-edge restoration runway, of the type frontally involving two arms with means for picking -up the bulk material in front of their path and means for the conveying on a downstream blending machine, which includes between the wheels or front tracks and wheels or rear tracks, suction means (SA) for sucking all that granulated material and dust which the front pick-up means have failed to collect from the underlying paving is provided.
  • SA suction means
  • Purpose of the present innovation is to realise a new train particularly suitable to the cold working and laying of the material, without the drawbacks, complexity, problems, of the prior cold arts and of the as much complex hot laying arts.
  • the mixer to form a cold recycle self-propelled train for the road paving rehash, of the type involving:
  • mixing means and said binder material spreading means provide:
  • a towing vehicle provides to feed the fluid bitumen to said mixer in said spraying ramp.
  • cement binder favours a fastest absorption in the mixture of the waste water after the new layer rolling, making the new paving more rapidly practicable.
  • the additive materials to the bitumen are amines in the 1/3% percentage, which favour the realisation of the mixture.
  • the amount of bitumen is advantageously provided in about 2-4%, advantageously in about 3% of the material to be recycled (aggregates).
  • the amount of water for the bitumen foaming advantageously ranges within a 2 to 5 % value.
  • the mixing vehicle according to this invention includes:
  • Substantially said mixing means and said binder material delivering means provide:
  • a continuous mixer (P1) with double axis (Ax) with co-penetrating blades or crossing blades (PO) and discharge at one end (S) is used while on the top the spraying ramp extends (P12) with a plurality of sprayers comprising an additived bitumen duct (B+AD), that gets through an interchangeable gauger (U1) to flow in a turbulence pre-chamber where the water is injected under pressure (H2O), which is tightly mixed with the bitumen and additive (B+AD) and exits from the spraying nozzles with rapid expansion of the water particles that immediately evaporate foaming the material, which falling above the mixer (P1) is mixed with the aggregate together with the liquid cement mortar (M).
  • B+AD additived bitumen duct
  • U1 interchangeable gauger
  • PLC Process Control Coding Logic Computer
  • M variable motor
  • tacho-dynamo tachymetric dynamo or tachymeter-dynamo, P6.
  • a by-pass (BP) in the bitumen feeding for the recirculation in case of delivery stop to the mixer is provided.
  • the computer-controlled system determines and controls all the parameters for a regular continuous working.
  • mixing vehicle is endowed with the following devices or units:
