BAM

What BAM does

Bayerische Asphaltmischwerke GmbH & Co. Kommanditgesellschaft für Straßenbaustoffe (bam) is a Bavarian asphalt manufacturer founded in 1969 and headquartered in Hofolding, Germany, operating a network of more than 40 owned production sites plus affiliated plants. The company is a wholly-owned subsidiary of Basalt AG, a diversified German conglomerate group, and runs six operating subsidiaries (AMB, AME, AMW, GBH, HWR, and Inn-Asphalt-Mischwerke) covering plant operations, stone quarrying, and material processing. BAM produces standard asphalt concrete grades (Asphaltbeton, Splittmastixasphalt, Gussasphalt), noise-reducing open-porous asphalt (bam flüstra), cold repair asphalt (bam Kaltasphalt), colored asphalt (bam COLOUR), liquid-tight silo asphalt for JGS/biogas facilities (DEUSEAL), and a next-generation recycled-content line (bam OPTIMATE) that uses up to 100% reclaimed asphalt granulate via parallel-drum counter-current recycling systems. Quality control is run under DIN EN 13108 with central and per-plant laboratories.

The business model is a quote-based, B2B direct-sales operation. Customers — Bavarian state and municipal road authorities, construction companies (Bauunternehmen), airport operators, and the agricultural sector — purchase or take delivery from regional branch offices (Munich, Nuremberg/Bamberg, Augsburg, Würzburg, Plattling), with products shipped by company or contracted truck fleets or picked up at production sites. Recycled asphalt is sourced back through GBH's crushing/screening operations, creating a closed-loop feedstock that supports both cost efficiency and the company's Umweltpakt Bayern, KUMAS, ISO 50001, and TÜV Entsorgungsfachbetrieb environmental positioning. Revenue is transaction-based across asphalt sales, granulate processing fees, and subsidiary hardware-style sales; pricing is not publicly disclosed and contracts typically net within 30 days of invoice.

Management comprises two Managing Directors (Geschäftsführer), Dipl.-Ing. Michael Liegl and Dipl.-Ing. Matthias Schellenberger. The company is privately held under Basalt AG, has been a kununu Top-Company employer four years running (2022-2025), and holds DIBt building approval for DEUSEAL along with CE marking across its road-construction product line. Financials including revenue are not publicly disclosed.
