Problems solved by technology

However, as far as the existing coal tar pitch road construction oil is concerned, due to its poor adhesion to aggregates, easy flow at high temperature, brittle cracking at low temperature, and poor aging resistance, it can no longer meet the needs of modern traffic road construction.

Embodiment 1

[0015] The medium-temperature bitumen with a temperature of 360°C from the bottom of the secondary tower is directly sent to the soft coal pitch high tank, and the anthracene oil is slowly pumped into the coal from the tank according to the ratio of medium-temperature bitumen: anthracene oil = 25:75 Put the asphalt in a high tank, stir it with a stirrer for 5 hours, and keep the final temperature at 150°C, take a sample and analyze it, and get the road oil product after passing the test.

Embodiment 2

[0017] The medium-temperature bitumen with a temperature of 360°C coming out of the bottom of the secondary tower is directly sent to the soft coal pitch high tank, and the anthracene oil is slowly pumped into the coal from the tank according to the ratio of medium-temperature bitumen: anthracene oil = 35:65 Put the asphalt in the high tank, stir with a stirrer for 6 hours, and keep the final temperature at 150°C, take a sample and analyze it, and get the road oil product after passing the test.

Embodiment 3

[0019] The medium-temperature bitumen with a temperature of 360°C from the bottom of the secondary tower is directly sent to the soft coal pitch high tank, and the anthracene oil is slowly pumped into the coal from the tank according to the ratio of medium-temperature bitumen: anthracene oil = 30:70 Put the asphalt in a high tank, stir it with a stirrer for 7 hours, and keep the final temperature at 150°C, take a sample for analysis, and get the road oil product after passing the test.

Abstract

An oil for building rod is prepared from medium-temp asphalt and anthracene oil. Its advantages are high stability, quality and content of asphalt, and proper softening point of distilled residue.

Description

technical field [0001] The invention relates to a road construction oil and a production method thereof, in particular to a production method of modified coal tar pitch road construction oil. Background technique [0002] With the rapid development of traffic road construction, it is required that asphalt and road construction oil used on traffic roads must have excellent ductility, elastic-plasticity, and aging resistance. Most of the existing asphalt pavements use a high-quality pavement regeneration sealant mixed with coal tar pitch produced by coking plants and petroleum pitch produced by oil refineries. This sealant combines the advantages of coal tar pitch and petroleum pitch. Both stability and extensibility have been improved to a certain extent. However, as far as the existing coal tar pitch road oil is concerned, due to its poor adhesion to aggregates, easy flow at high temperature, brittle cracking at low temperature, and poor aging resistance, it can no longer m...
