Bitumen/asphalt modification

Viscosity Reduction for Smart Construction.
The addition VESTOPLAST® or VESTOWAX® resp. GTL Sarawax to the bituminous binders used in road construction does not only enhance the performance of road surfaces, it also makes construction work easier and safer.

Waterproofing membranes and joint fillers - Bitumen modification.
The addition of POLYVEST® HT to bituminous binders accelerates performance and elongations and makes system cost more efficient.

TEGO® Addibit is a well-known range of additives for bituminous coatings and asphalt applications like e.g. emulsifiers.

Evonik is providing a broad range of technologies to serve the road construction industry. VESTENAMER® and TEGO® Addibit products provide solutions for today‘s requirements such as durability, reduction of emissions and energy consumption, and thus support sustainable road construction and maintenance.

VESTENAMER® has been used as an additive in the rubber industry for years. By virtue of its properties, the versatile polyoctenamer can solve a variety of problems in the compounding and processing of rubber. It can also improve the dynamic properties of the vulcanized material and as well be used to recycle waste rubber.

Roofing / Water proofing
High melting grades from Evonik’s VESTOPLAST® range of amorphous poly-alpha-olefins often are component in polymer modified bitumen (PmB) for the production of high-grade membranes for roofing and bridge construction. Beside excellent performance within a broad temperature range, PmBs containing non-reactive thermoplastic VESTOPLAST as a modifier are particularly well suitable for recycling processes, which are becoming more and more important.
