Cariphalte

Cariphalte is a branded range of hot-pour rubberised bitumen sealants manufactured by Shell Bitumen. The products are based on bitumen technology and are designed for infrastructure applications in which a flexible, durable seal is required. Reported uses include concrete roadways, expansion joints, and race-track surfaces. The brand entered commercial use in 1986. Its documented application history includes road infrastructure in Cleveland and Kent, as well as major routes and structures such as the Dartford Crossing, the A4, the A10, the M2, and the M20. These references place Cariphalte within the specialist road-building and civil-engineering materials sector rather than the consumer adhesives or general construction-products market. Two Cariphalte formulations are identified in the available reference material. Cariphalte DM is based on a styrene block copolymer, specifically styrene-butadiene-styrene (SBS). SBS modification is used in bitumen technology to improve elastic and performance characteristics relative to conventional unmodified bitumen, although the available source does not provide a full technical specification for the product. Cariphalte DA is associated with friction-course mixtures, which are road-surfacing mixtures intended to provide suitable surface texture and skid resistance. Cariphalte’s market proposition is therefore performance-oriented and infrastructure-focused: the brand supplies specialised bituminous sealing materials for demanding civil-engineering applications. The available material does not identify a separate corporate entity, retail channel, current product catalogue, headquarters, ownership structure beyond Shell Bitumen, or present geographic footprint. It also does not establish whether the brand remains actively marketed under the Cariphalte name. Accordingly, its current status and contemporary commercial scope remain unconfirmed.

Cariphalte is documented as a Shell Bitumen brand specializing in hot-pour rubberised bitumen sealants. Its development belongs to the wider evolution of modified-bitumen materials for civil engineering, where sealants must accommodate movement, temperature variation, traffic loading, and the interfaces between concrete or asphalt elements. Unlike a general-purpose consumer brand, Cariphalte was specified for infrastructure and specialist surfacing work. The brand was released for commercial use in 1986. The available reference material does not identify an individual inventor, a separate founding company, or the precise location of its initial launch. It does, however, associate the product with Shell Bitumen, indicating that Cariphalte was commercialized within Shell’s bitumen-technology activities. Two formulations are identified. Cariphalte DM uses a styrene block copolymer, described as styrene-butadiene-styrene (SBS). Polymer modification is a significant technical approach in bitumen products because it can provide greater flexibility and resilience than conventional binders, although no complete performance data or formulation history is available in the supplied sources. Cariphalte DA is identified as a material used for friction-course mixtures, linking the brand to road-surface construction as well as joint and crack-sealing work. The brand’s documented application record includes concrete roadways in Cleveland and Kent and major United Kingdom transport infrastructure, including the Dartford Crossing, the A4, the A10, the M2, and the M20. These examples indicate use in substantial highway and roadway projects, but the available material does not provide project dates, contractors, quantities, specifications, or procurement details. It therefore supports recognition of the brand’s infrastructure role without permitting a more detailed project-by-project chronology. The Shell Bitumen Handbook is cited as further reading for the technical context of Cariphalte and related bitumen technologies. No supplied source establishes the current availability of Cariphalte, subsequent reformulations, discontinuation, a current website, or an independently reported operating market. The historical record is consequently clearer than the brand’s present commercial status.

  Commercial release

  [1]Cariphalteen.wikipedia.org

  Cariphalte was released for commercial use as a hot-pour rubberised bitumen sealant brand associated with Shell Bitumen.

A specialist infrastructure-materials brand positioned around hot-pour rubberised bitumen sealing performance for roads, expansion joints, race tracks, and related civil-engineering applications.

• SBS-modified hot-pour bitumen sealant

  Cariphalte DM

  Cariphalte DM is identified as a styrene block copolymer formulation using styrene-butadiene-styrene (SBS). It belongs to the brand’s rubberised bitumen range and is intended for specialist sealing applications in civil engineering. The available material does not provide detailed installation temperatures, performance ratings, packaging, or current availability.

• Bitumen material for friction-course mixtures

  Cariphalte DA

  Cariphalte DA is described as being used for friction-course mixtures in road-surfacing work. Its documented role connects the brand with surface-course applications where the road finish must provide an appropriate texture and level of friction. The supplied reference does not state when DA was introduced, provide a complete formulation, or confirm whether it remains commercially available.
