Bitumen Additives High Modulus Polymer Asphalt Modifier

EZRoad versatile asphalt additive (VAA) has the functions of asphalt high-viscosity agent, anti-rutting agent, anti-stripping agent, asphalt toughening agent, high-modulus modifier, etc., and even its various properties are better than the modifiers on the market. At the same time, the direct injection method of EZRoad versatile asphalt additive simplifies production, makes it easier to use, and greatly improves production efficiency and process reliability.

EZRoad versatile asphalt additive is directly put into the base asphalt (or ordinary modified asphalt) for fusion reaction, and the chemically cross-linked multi-copolymer modified asphalt can be obtained, which has the following excellent properties:

1. It forms a permanent strong cross-linked material with the asphalt binder and forms a three-dimensional elastic network together, giving the asphalt toughness and elasticity.
2. The high and low temperature performance of asphalt is improved by more than 2 times at the same time, and it can withstand various extreme temperatures. High temperature resistance to flow, medium temperature construction, low temperature resistance to cracking.
3. High peeling resistance, strong bonding between asphalt and aggregate, so that the tensile strength of asphalt is more than 3Mpa.
4. It increases the specific toughness and strength of the asphalt, and the anti-rutting and fatigue cracking properties of the asphalt pavement by 3 times, and prolongs the service life of the pavement.
5. Enhance the stability of asphalt, asphalt can be produced and stored during non-construction seasons.
6. The construction temperature of the asphalt mixture is reduced, the compaction time is short, the open traffic is fast, and the social and environmental protection benefits are high.

Adding EZRoad VAA to base asphalt and ordinary SBS modified asphalt can obtain cross-linked modified asphalt with various PG classifications and various performance conditions. The following table shows the VAA modification effect of a domestic brand of base asphalt and ordinary SBS modified asphalt in the market, which is only for reference of the modification effect.

EZRoad versatile asphalt additive can be widely used in various occasions that need to improve the performance of asphalt, and the direct-injection VAA is suitable for various asphalt grading, and has no effect on the grading of the asphalt mixture. VAA can be applied to the following situations:

1. It is applied to improve the performance of asphalt at intersections and heavy-duty traffic pavements;
2. Overloaded and compressive pavement in factories, mines, ports and logistics parks;
3. Dry on-site modification of high-viscosity asphalt required for drainage pavement, large-pore pavement, etc.;
4. On-site modification as dry SBS, direct injection modifier;
5. It is added to the colored asphalt pavement to improve the durability of the pavement;
6. As a core modified material for export, it solves the difficulties of lack of modified asphalt supporting equipment and
industrial chain in overseas markets;
7. Various scenarios that need to improve the high temperature, low temperature and fatigue performance of asphalt in multiple directions at the same time.

EZRoad versatile asphalt additive package is 5kg/bag, and one box load four bags of 20kg. It can be put into the mixing tank without opening the bags.
