Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paving machine or a compounding plant for laying an asphalt mixture or the like, and a method for managing paving work, and more particularly to a paving machine having means for recording data measured by the sensor. TECHNICAL FIELD The present invention relates to a pavement construction management method capable of easily recording construction conditions and the like for laying a plywood using the same and a plywood plant.

[0002]

[Future technology] Conventionally, in laying construction of asphalt mixture using a paving machine such as an asphalt finisher, a shipping slip of the asphalt mixture in a mixture plant and a construction record of the asphalt finisher construction site are created. That is, in the mix plant, when shipping the asphalt mix, the shipment tonnage of the asphalt mix,
Issue a handwritten slip stating the type of asphalt mix, shipping temperature, etc. and hand it to the driver of the dump truck that conveys the asphalt mix. The mix plant manages the shipping slip, which is a copy of the handwritten slip.

When the driver of the dump truck arrives at the construction site of the pavement, he hands it over to the driver of the handwritten slip asphalt finisher. The driver of the asphalt finisher refers to the handwritten slip handed to him and performs the laying work of the asphalt mixture. When the supply of asphalt mixture from the dump truck to the asphalt finisher is completed, the temperature of the supplied asphalt mixture is measured and recorded, and the asphalt mixture is laid. Measure and record the temperature of the asphalt mix even after laying it. For the measurement of the temperature of the asphalt mixture at the time of supply, each time the dump truck arrives, a worker holds a contact-type thermometer in hand and inserts a probe into the mixture to record data. Also, take a picture when inserting the probe. Even at the time of measuring the temperature of the asphalt mixture after laying and leveling, the work of inserting the probe into the asphalt mixture at every measurement point provided at intervals of 20 m and taking photographs are repeatedly performed.

The shipping slips and the construction records created at the pavement site in the composite material plant serve as the basis for reports submitted to administrative ministries and materials for improving the efficiency of construction.

[0005]

However, in the case of laying construction of asphalt mixture as described above, the following problems have occurred. That is, in the laying work, there is a problem that the construction man-hours for measuring the temperature of the asphalt mixture are enormous and the work period is extended. Moreover, in the case of large-scale construction with more than 50 dump trucks, the above problems become more prominent, and errors in temperature measurement etc. increase, making it possible to create effective materials for construction efficiency. There is also the problem of becoming impossible.

Further, the conventional temperature measuring method using the above-mentioned probe requires a lot of time for the work, so that an error may occur especially in the asphalt mixture after laying. That is, even though the asphalt mixture supplied from the dump truck to the hopper of the asphalt finisher falls below the hopper and is spread and air-cooled immediately after it is laid, it takes time to perform the measurement work. Even in the part where the temperature is measured, a temperature difference occurs in the order of temperature measurement.

In addition, the preparation of the above-mentioned report and data requires a great deal of labor for processing a huge amount of data such as the measured value of the mixture temperature and the mileage of the dump truck. There is also a problem that it causes an increase in construction costs for the material laying work.

The present invention has been made in view of the above-mentioned problems, and by providing a non-contact infrared radiation temperature sensor on a paving machine, the temperature measurement of a mixture laid on the paving machine is automated and its accuracy is improved.
