EMULPEN is an asphalt emulsion, dark brown in color, developed for priming of base layers and granular soils. It is an ecological product, since it uses water as an application vehicle, allowing application with homogeneous dosage rates with low viscosities. It can be used in compacted soils with humidity of up to 4%.

The income from EMULPEN varies according to the characteristics of the base layer or soils (more porous or less porous), presenting a range of 0.8 to 1.2 L / m², and requires a total priming period of 24h to 36h, depending on the conditions and soil characteristics and ambient temperature.
