Embodiment 1

[0037] A kind of rare earth compound modified pitch is composed as follows in parts by weight:

[0038]

[0039]

[0040] The preparation method of the modified asphalt is as follows: first, the base asphalt is metered into the asphalt tank with a stirring device through a flow meter and heated to 120-140 ° C, and the rare earth compound is added into the tank according to the specified ratio and stirred for 30 minutes, and then the temperature is raised To 185-190 ℃, add rock asphalt into the tank according to the specified proportion, and stir and mix thoroughly for 20-30 minutes. After processing, pump it into a storage tank and incubate for 1-2 hours before use.

Embodiment 2

[0042] A kind of rare earth compound modified pitch is composed as follows in parts by weight:

[0043]

[0044] The preparation method of this modified pitch is the same as in Example 1.

Embodiment 3

[0046] A kind of rare earth compound modified pitch is composed as follows in parts by weight:

[0047] Binhua 90# ​​asphalt 85

[0048] 1-1000nm cerium oxide 0.5

[0049] Qingchuan rock asphalt 12.

[0050] The preparation method of this modified pitch is the same as in Example 1.

Abstract

The invention relates to rare-earth modified asphalt and a preparation method thereof. The rare-earth compound modified asphalt is prepared from, by weight, 80-95 parts of matrix asphalt, 0.1-3 parts of rare-earth compounds and 4.9-20 parts of rock asphalt. The rare-earth compound modified asphalt has the advantages of being insensitive to temperature changes, free of cracks at low temperature and long in service life, resisting to tracks at high temperature, resisting to ageing, resisting to stripping and the like, the production process is simple, energy consumption is low, and cost is low. The modified asphalt has wide application prospects in building of roads and bridges.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to a rare earth modified asphalt and a preparation method thereof. Background technique [0002] Asphalt has excellent plasticity and cohesiveness, and has a long history of being used as road and bridge pavement materials. my country has a vast territory, and the natural environment such as temperature, humidity, and light varies greatly between the north and the south. With the rapid development of my country's national economy and the rapid increase in traffic volume, ordinary asphalt concrete pavement is facing a severe test. In the construction of roads and bridges at home and abroad, the performance requirements for asphalt materials are becoming more and more stringent. It is required to resist rutting at high temperatures, not crack at low temperatures, resist water damage, etc., and hope to have a long service life. Petroleum asphalt or ordinary natural Bitumen does not me...
