Problems solved by technology

[0003] Normal temperature modified asphalt can be produced in the range of minus 20 degrees Celsius to 50 degrees Celsius. At present, there is no small indoor test processing equipment for simulating on-site production conditions in the market, and it is impossible to simulate the on-site processing temperature and stirring speed of room temperature modified asphalt.

specific Embodiment

[0042] As a specific example, if it is desired to process normal temperature modified asphalt at minus 10°C, the dosage of the modifier is 15%, the quality of the base asphalt is 2.0kg, and the stirring speed is 200r / min.

[0043] (1) Calculate the amount of modifier and the amount of asphalt put in each batch.

[0044] The total amount of modifier = mass of base asphalt × modifier dosage = 2.0kg × 15% = 0.3kg

[0045] The mass of each batch of base asphalt = the total amount of modifier / 2=0.3kg / 2=0.15kg

[0046] Batch quantity = mass of base asphalt / mass of each batch of base asphalt = 2.0kg / 0.15kg≈14 times

[0047] (2) Turn on the temperature control system of the environmental box, make the temperature of the environmental box reach the predetermined temperature: -10°C, and keep the temperature constant for more than 30 minutes.

[0048] (3) Put 0.3kg modifier into the processing barrel at one time;

[0049] (4) Put 0.15kg of the first batch of asphalt into a processing ...

Abstract

A small normal temperature modified asphalt processing device for indoor tests is mainly characterized by including an environmental box, a temperature control module, a speed control module, a stirrer, a stirrer lifting control module and a processing barrel; the device comprises a heating temperature adjusting system and a refrigeration temperature adjusting system which are mutually independent, and the temperature is in a range of -20 DEG C to +50 DEG C; the processing barrel is fixed in the environmental box; the stirrer fixed in the environmental box and located above the processing barrel is controlled by the stirrer lifting control module and the speed control module and performs stirring in the processing barrel; a built-in temperature sensor is electrically connected with the temperature control module, is mainly used for controlling and displaying a processing temperature in the processing barrel, and is placed at the tail end of the center of a stirring impeller rotating rod. The device is portable, can really simulate a processing environment of normal temperature modified asphalt in the range of -10 DEG C to +50 DEG C, conveniently determines the processing parameters of the modified room temperature asphalt such as the temperature, the rotation speed and the modification agent mixing amount, and can provide samples for indoor detection of properties of the room temperature modified asphalt.

Description

technical field [0001] The invention relates to a small normal-temperature modified asphalt processing equipment for indoor testing. Background technique [0002] "Normal temperature" is mainly relative to hot mix, warm mix and cold mix, and its meaning mainly means that the mixing temperature of asphalt mixture is lower than that of ordinary hot mix and warm mix asphalt mixture, and at the same time, the aggregate needs to be heated To remove moisture, asphalt binder needs to be constructed at 90°C~100°C, and the mixing temperature is higher than that of general cold mix materials; however, the paving and rolling temperatures of room temperature modified asphalt are comparable to that of general cold mix materials. Pave and roll in the temperature range of 50°C to minus 20°C. The emergence of room temperature modified asphalt can make up for the technical defects of poor pavement performance and unsuitable full-width paving and use of water medium room temperature material...
