1. a kind of modified pavement asphalt production technology, it is characterized in that it the following steps are included:

Pitch is put into progress emptying in oil unloading trough and obtains material asphalt, material asphalt is then pumped into high temperature by step 1 It is heated at 120-130 DEG C in tank, the material asphalt after heating is successively finally pumped into heat exchanger and with agitating device In reactor；

SBS rubber is transported to by the weight for accounting for material asphalt total weight 3-8% equipped with material asphalt by step 2 under normal pressure In reactor with agitating device, formed under conditions of 130-135 DEG C by strong stirring 16-18 hours with material asphalt Mixture adds the lubricating oil for accounting for material asphalt total weight 1.5-3.5 ‰ so that SBS rubber gradually mixes with material asphalt Basestocks and the lignocellulosic for accounting for material asphalt total weight 1.5-3.5 ‰ are made after mix 16-18 hours again with material asphalt Modified pavement asphalt, the temperature of modified pavement asphalt is at 120-130 DEG C.

2. modified pavement asphalt production technology according to claim 1, it is characterized in that the SBS rubber of step 2 is to pass through spiral shell Rotation conveyer is transported in the reactor with agitating device.

3. modified pavement asphalt production technology according to claim 1, it is characterized in that the high-temperature tank and with stirring The level gauging of the reactor of device uses U.S. Edmund spy pressure sensing transmitting system.

4. modified pavement asphalt production technology according to claim 1, it is characterized in that described is anti-with agitating device It answers and is connected with PLC intelligence control system on device.

Technical field

The present invention relates to a kind of modified pavement asphalt production technologies.

Background technique

For current process for preparing asphalt since material addition is unable to control, application condition is big, causes institute's formed asphalt Performance is poor, and the process prepared is also more complicated.

Summary of the invention

The present invention provides a kind of modified pavement asphalt production technologies, and the parameter that it is not only prepared is more accurate, and make Standby asphalt performance is relatively good.

The invention adopts the following technical scheme: a kind of modified pavement asphalt production technology, it is characterized in that it includes following Step: pitch is put into progress emptying in oil unloading trough and obtains material asphalt, material asphalt is then pumped into high temperature by step 1 It is heated at 120-130 DEG C in tank, the material asphalt after heating is successively finally pumped into heat exchanger and with agitating device In reactor；SBS rubber is transported to by the weight for accounting for material asphalt total weight 3-8% under normal pressure and is dripped equipped with raw material by step 2 In the green reactor with agitating device, pass through strong stirring 16-18 hours under conditions of 130-135 DEG C with material asphalt It forms mixture and adds the profit for accounting for material asphalt total weight 1.5-3.5 ‰ so that SBS rubber gradually mixes with material asphalt Lubricant base material and the lignocellulosic for accounting for material asphalt total weight 1.5-3.5 ‰ and material asphalt are again after mix 16-18 hours Modified pavement asphalt is made, the temperature of modified pavement asphalt is at 120-130 DEG C.

The SBS rubber of step 2 of the present invention is transported in the reactor with agitating device by auger conveyor.Institute The level gauging of the high-temperature tank and the reactor with agitating device stated uses U.S. Edmund spy pressure sensing transmitting system.Institute PLC intelligence control system is connected on the reactor with agitating device stated.

The invention has the following advantages: the parameter that the present invention is not only prepared compares after using above technical scheme Accurately, and the asphalt performance of preparation is relatively good.The present invention uses advanced PLC intelligence control system, and computer shows technique stream Journey, technological parameter is very clear, has the characteristics that the height that process control is accurate, material metering is accurate, simple and clear, described The level gauging of warm tank and the reactor with agitating device uses U.S. Edmund spy pressure sensing transmitting system, control errors Within 0.2%.Temperature control is shown in such a way that teletransmission liquid crystal display combines using scene temperature table, guarantees technological temperature Accuracy.While in order to guarantee the safety of equipment in use.
