LAIEX, world-leading company in asphalt polymers, is consolidated in the asphalt road and highway construction sector, guaranteeing quality and durability.

The increase in traffic volume and vehicle weight requires the development of new asphalt mixtures with better performance. And that is where Laiex comes in, in the design of these new asphalt mixtures:

In adding polymers to improve road performance and extend their lifespan.

Our objective:

+ longer lifespan of roads, – less road maintenance.

Main effect of adding polymers to asphalts: Potential improvement in viscosity-temperature ratio

ADVANTAGE: More resistant at extreme temperatures

LAITEX BX-478

Hot Modification

Anionic styrene butadiene latex.

We present a NEW TECHNOLOGY to modify hot asphalt,

LAITEX BX-478, anionic butadiene styrene latex.

Properties

Specifically designed to withstand high temperatures without affecting its structure and mechanical properties, and with a highshear resistance. The modification with high solid styrene-butadiene latex is a simple process to improve the final properties of asphalt. The incorporation of LAITEX BX-478 generates a polymer network that increases the viscosity of the asphalt and therefore its resistance to sagging.

Advantages

The process of modifying the asphalt withLAITEX BX-478 saves 15% on heat energy compared to the modification with SBS polymer. When modifying the asphalt with emulsion polymer LAITEX BX-478, there is a 50% increase in the productivity of the industrial modifier plant.

LAITEX B-754

Cold modification

High solid butadiene styrene latex

to formulate cationic asphalt emulsion.
