BITAREL BTL Hot applied joint sealant Type N2 is composed of petroleum bitumen, polymer and target texturing agents.
Scope of application
BITAREL BTL Hot applied joint sealant Type N2 is used to seal contraction joints and cracks of all concrete and asphalt concrete pavements.
Benefits
- complies with the requirements of STB EN 14188-1-2009, type No. 2 “Joint fillers and sealants. Part 1. Technical requirements to hot applied sealants“;
- high heat resistance;
- low-temperature flexibility;
- good adhesion to asphalt coating;
- resistance to cyclic deformations;
- water resistance;
- ease of laying;
- recyclability.
Base preparation
Prior to application of joint sealant, the asphalt surface should be free of dust, dirt, debris and oils. Under wet or ice conditions, the surface should be blown down with compressed air.
The area of the repairable crack should be dry and free of loose parts.
It is recommended to pre-coat cracks with BitaGrunt Bitarel primer.
Product preparation
The sealant should be heated in a mastic pot equipped with a mixer to a free flowing state of 160-180 °C.
Product application
The sealant is applied in a heated liquid state.
Sealant cooling may lead to shrinkage that requires refilling to be performed immediately after the first one.
Use the filling method to eliminate removal of excessive sealant.
