Cement bound granular material (CBGM)

Cement Bound Granular Material (CBGM) is a type of hydraulically bound mixture commonly used in road construction and other applications. It provides a cost-effective and durable alternative to traditional flexible materials, offering long-lasting performance. CBGM is a blend of aggregates, cement, and water and is transported in tippers and laid using a paver.

CBGM offers a robust solution for constructing, long-lasting pavements rapidly. It provides a substitute to the more conventional flexible materials, such as Asphalt Concrete Heavy Duty Macadam (AC HDM), a dense, high-performance asphalt mixture designed for heavy traffic applications, often used as a base or binder course.  

What applications can CBGM be used for?

CBGM is versatile in application and comes in multiple variants. Depending on the strength requirements, CBGM can incorporate a wide range of aggregates, including recycled and manufactured aggregates.CBGM is particularly well-suited for heavier applications where robust, durable construction is required. It also provides a solid, stable foundation for traditional asphalt to be laid upon.

Typical applications include:

• pavement construction suitable for foundations or pavement bases, including major trunk roads
• ports ideal solution to withstand the heavy demands of ports and harbours applications
• airports
• industrial and commercial - suitable for installation in most external loading and storage environments.  

What benefits can CBGM provide?

• Cement Bound Granular Mixtures (CBGM) are effective for incorporating multiple internally produced materials within your business.
• CBGM specifications allow for the use of recycled materials, helping develop lower-carbon products.
• Our plant's advanced blending capabilities ensure precise aggregate mixing, meeting grading specifications.
• This flexibility supports material experimentation and allows the use of stockpiled, lower-quality, or capped materials.
• By reducing waste and enhancing sustainability, CBGM contributes to a more environmentally friendly approach.
