Anti-rutting agent

Anti-rutting agent

LVJIAN® anti-rutting agent is a kind of asphalt mixture additive composed of a variety of polymers. It greatly improves the high-temperature stability of the asphalt mixture through the multiple effects of tackifying, stiffening, filling, asphalt modification, and elastic recovery on the surface of the aggregate, and also improves the water stability and low-temperature crack resistance of the mixture.

Performance

Embedded squeeze effect

The anti-rutting agent softens during the construction process due to the high temperature. These particles are thermoformed during the rolling process, which is equivalent to a single-size fine aggregate with high adhesion filling the gaps embedded in the aggregate skeleton, increasing The skeleton function of the asphalt mixture structure is strengthened, the interaction between the mixtures is strengthened, the mixtures are closer, the permeability of the formed pavement is reduced, and the ability of the asphalt mixture to withstand loads is increased.

Reinforcement effect

Due to the microcrystalline area formed by the polymer in the anti-rutting agent has considerable stiffness, it is partially drawn into plastic fibers during the mixing process, and bridges and crosslinks within the aggregate skeleton to form a fiber stiffening effect. Due to the presence of polymer fibers, it forms a network in the cement, strengthening the interaction and integrity of the asphalt slag cement system.

Cementation

The anti-rut agent is put into the mixing pot of asphalt mixture. At a temperature of 170 ~ 180 ° C, it is first softened by dry mixing with the mineral material, and the asphalt is continued to be mixed. Anti-rut particles and asphalt become cemented, so that the asphalt performance is improved. The softening point of the asphalt is increased; the sensitivity to temperature is reduced; the adhesion of asphalt to the mineral is increased.

Deformation recovery

The elastic component of the anti-rutting agent has the function of elastically recovering the deformed part of the pavement at a higher temperature, thereby reducing the permanent deformation of the Shaped asphalt pavement.

Application

● Highway: highway and high grade highway, especially suitable for high temperature area, heavy traffic section and long longitudinal slope section;

● Municipal roads: municipal trunk roads, bus lanes, etc., especially suitable for intersections and bus stops;

● Airport ports: airport runways, container stacking sites, industrial facilities land and other roads and sites required to bear heavy loads; Roads and sites requiring heavy loads;

● Pavement maintenance: various pavement maintenance and pit repair, covering asphalt concrete to cement pavement, etc.
