Ensuring that tender submissions meet the required bitumen mastic asphalt specifications is crucial for achieving optimal performance and durability. Contractors and suppliers must adhere to the precise British Standards (BSS) to guarantee compliance and consistency in project execution.
Key Specifications of Bitumen Mastic
1. Grade & Type of Mastic Asphalt
Bitumen mastic can be categorized based on the type of aggregate used:
- Natural Rock Aggregate Mastic
- Limestone Aggregate Mastic
Each type must comply with the relevant British Standard Specifications (BSS), ensuring consistency in asphaltic cement composition as outlined in the designated tables and column numbers.
2. Standard Compliance & Asphaltic Cement Selection
- The asphaltic cement type must align with the required BSS table references, ensuring the correct viscosity, penetration, and performance.
- Contractors must be informed about the required isolating membrane, such as:
- Sheathing Felt
- Fiberglass Tissue
- Kraft Building Paper Underlay
3. Surface Reflective Treatments
To enhance durability and weather resistance, the bitumen mastic surface may require a reflective treatment, including:
- Aggregate Chippings for anti-slip properties
- Bituminous Aluminium Paint for heat reflection
- Acrylic Coloured Paint for aesthetic and protective coating
Mastic Asphalt Standards for Tendering
Architects, engineers, and quantity surveyors should specify the exact BSS standards for mastic asphalt in tender invitations. This ensures that the recommended asphaltic cement composition is used for each application, maintaining high-quality and long-lasting results.
