LABOUR BASED SURFACING TECHNOLOGY
On Site Production of Labor Based Asphalt.
Pavement Materials Group offers project site support for contractors and engineering companies planning to manufacture premix asphalt on site, either for immediate usage or stockpiling for future use.
Our Labor Based Asphalt was designed for on-site or off-site production using conventional concrete mixers or hand mixing using our Asphalt Filler, Bitumen Emulsion and Selected Aggregates. Selected aggregates can be sourced locally, reducing transportation costs and supporting local quarries. Designed to support employment creation, Pavement Materials Group assist.
High Performance Asphalt, with an extended shelf life
HPC Labor Intensive Surfacing Asphalt was developed to address the generic problems of other Asphalt brands and presents benefits to the Environment, Contractor and Community through reduction in equipment requirements, creating jobs for the community and lowering cost of tar asphalt surfacing projects.
HPC Labor Intensive Asphalt Mix Design
Crusher sand (<6mm) | 50% |
Anionic Binder (60% Net) | 9 % |
HPC Carbon Asphalt filler | 20% |
6,7/9.5mm road stone | 21% |
THE GRADING OF HPC PREMIX ASPHALT COMPLIES WITH TRH-8 ROAD SPECIFICATIONS
Onsite Preparation & Usage Procedure
ONSITE HPC CARBON ASPHALT PREPARATION
- Mix the required quantity of HPC Carbon filler, crusher-sand and road stone.
- Add the required quantity of bituminous emulsion Binder and mix thoroughly.
HPC Premix Cold Asphalt Applications
- Rural and residential roads
- Road maintenance and repair
- Labor intensive road construction
- Pothole Repairs
- Driveway Construction
HPC ASPHALT APPLICATION
- Ensure that the base layer is well compacted to the required density and is swept free of loose material.
- Lightly water the base sweeping off any free standing water immediately (no prime is required).
- Place the prepared HPC Cold Asphalt mix at regular intervals and level to the required loose thickness.
- Lightly water the levelled mix.
- Compact using a roller with 4 - 6 passes (water the drums to assist with sticking of material).
- Apply additional water if required during compaction. Once the surface becomes saturated with a brown liquid, sufficient water and compaction has been applied.
ADVANTAGES OF HPC PREMIX ASPHALT
- Self-Priming
- No Heating Required
- Mix Design Conforms to South African TRH8
- Exceeds Design criteria for E4 Classification of Roads (TRH8)
- Easy Application – no Specialised Equipment Necessary
- Ideally Suited to Labor Based Construction
- Minimal Disruption to Traffic
- Cost Effective
