Problems solved by technology

The multiple technical solutions disclosed above generally have complex preparation processes, high cost, and large pollution, and do not really realize the normal temperature liquefaction and high viscosity of asphalt.
Since various additives are dispersed in the base asphalt at high temperature, they may segregate and agglomerate as the temperature drops during actual use, thereby affecting its road performance

Embodiment 1

[0026] 1. Preparation of reactive high-viscosity liquid asphalt

[0027] Weigh 55 parts of base asphalt, 30 parts of organic solvent and 20 parts of modifier in parts by weight. The organic solvent is prepared from linoleic acid, linolenic acid and sodium methyl silicate in a weight ratio of 10:10:2; the modifier is composed of GT012 type SBS latex, RWE10 type epoxy resin and liquid carbon system C9 type petroleum resin is formulated according to the weight ratio of 3:21:11. and prepared as follows:

[0028] (1) Heat the base asphalt weighed in parts by weight to 140°C and keep it warm for later use;

[0029] (2) Add the organic solvent to the base asphalt treated in step 1, stir at a speed of 100r / min for 10 minutes, and stir at a speed of 30r / min for later use;

[0030] (3) Add the modifier weighed by weight, and stir for 8 minutes at a speed of 120r / min to prepare a reactive high-viscosity liquid asphalt;

[0031] (4) Put the prepared asphalt into a container, keep it s...

Abstract

The invention discloses reactive high-viscosity liquid asphalt and a preparation method and application thereof. The reactive high-viscosity liquid asphalt contains, in parts by weight, 50-60 parts ofasphalt, 25-35 parts of an organic solvent and 15-25 parts of a modifier. A reactive high-viscosity liquid asphalt mixture which is obtained through mixing of the reactive high-viscosity liquid asphalt, an inorganic active powder curing agent and graded aggregate has the advantages of low cost, high strength, rapid strength development, convenient construction and a wide application range, can beused as a super-thin abrasion layer which is laid on an original pavement, and can also be applied to newly-built drainage pavements.

Description

technical field [0001] The invention relates to the field of road building materials, more specifically, the invention relates to a reactive high-viscosity liquid asphalt, a preparation method and application thereof. Background technique [0002] Compared with ordinary modified asphalt, high-viscosity asphalt has better viscosity and toughness, and has high bonding strength after being combined with aggregate. Traditional high-viscosity asphalt generally adopts hot mixing technology, which has the disadvantages of complicated preparation process, high cost and large pollution. In order to avoid the disadvantages of hot mix asphalt, warm mix asphalt and normal temperature asphalt have been developed one after another. Although warm-mix asphalt reduces the mixing temperature to a certain extent, it still needs to be heated during use, which does not fundamentally solve the problem. Emulsified asphalt and solvent asphalt are mostly used for room temperature asphalt, and the ...
