AGS ROAD PROJECTS

Advanced Soil Engineering, Road Stabilisation, Dust Control & Erosion Management

Afrivaar Global Solutions (AGS), together with AGS’s international engineering partner, delivers advanced soil, road, and dust-control technologies used successfully across Australia, and now being deployed through AGS in Africa, including DR Congo, Zambia, Botswana, Tanzania, Namibia, South Africa, Ghana and Angola .

These systems are engineered for mining, government infrastructure, industrial developments, and rural community networks, turning weak, dusty or water-susceptible ground into durable, long-lasting, high-performance roads.

ROAD STABILISATION

Using AGS Guardian™ Road Stabiliser Technology

AGS’s partner-developed stabilisation chemistry chemically binds in-situ soils, converting weak granular or clay materials into highly compacted, load-bearing pavement layers.
This removes the need for expensive imported gravel or asphalt in many cases.

This technology is used widely across Australia’s mining and rural road networks, and AGS is now applying it across Central, Southern and East Africa with excellent results in tropical, semi-arid and wet clay conditions.

Applications

  • Mining haul roads & pit access

  • Rural community connector roads

  • Agricultural transport routes

  • Industrial parks & construction access roads

  • Internal site roads and laydown yards



    AGS Step-by-Step Process — Road Stabilisation

    1. Site Assessment & Soil Investigation

    • AGS engineers analyse local soil, CBR values, Atterberg limits, particle composition, moisture content and plasticity.

    • Traffic loading, haul truck weights and climate factors are assessed.

    • This determines dosage, depth, and stabilisation method.

    2. Design & Treatment Plan

    • AGS designs layer thickness (typically 150–300 mm).

    • Selects the suitable AGS Guardian™ formulation (polymer-based, enzyme-enhanced or hybrid).

    • Calculates application rate for soil type and required strength.

    3. Surface Preparation

    • Clear loose material.

    • Grade and shape existing road.

    • Install drainage fall where needed.

    4. Scarifying the Road Layer

    • Scarify ground to the stabilisation depth.

    • Break up clumps to ensure uniform mixing.

    5. AGS Product Application

    • Uniform spray application of AGS Guardian™ Road Stabiliser using calibrated tankers/dosing units.

    • Application rate varies by soil and design thickness.

    6. Mechanical Mixing

    • Graders or rotary mixers incorporate stabiliser into soil.

    • Blend until homogenised, with consistent colour and texture.

    7. Moisture Conditioning

    • Bring soil to optimum moisture content (as per Proctor testing).

    • Ensure uniform moisture to avoid weak pockets.

    8. Compaction

    • Heavy vibratory roller compacts the treated layer.

    • Compaction targets: typically ≥ 98% modified Proctor.

    • AGS conducts in-situ density checks.

    9. Curing Phase

    • Allow 24–72 hours (depending on weather) for chemical bonding.

    • Light traffic permitted initially; full operations resume after cure.

    10. Optional AGS Surface Seal

    • For dusty or high-wear areas, AGS applies a polymer sealing coat (AGS Guardian™ Surface Seal).

    • Provides a smooth, waterproof, dust-free finish.

    11. Quality Testing & Verification

    • Post-treatment CBR testing.

    • Surface penetration resistance checks.

    • Rut-depth and lateral displacement measurements.

    12. Maintenance Schedule

    • AGS provides a long-term maintenance template:

      • light grading intervals

      • retouch application if needed

      • inspection after heavy rain

    The result is a stronger-than-gravel, lower-cost, long-life road surface built using the soil already available onsite.

DUST SUPPRESSION & FUGITIVE DUST CONTROL

Using AGS TotalDust™ Control Systems

AGS offers a complete dust management program using proprietary binding polymers, moisture-locking agents, and surface sealants from AGS’s partner technology, applied and branded as AGS systems.

This technology is extensively used in Australian mining operations, where dust levels and PM standards are tightly regulated.

Haul roads

  1. Access roads

  2. Stockpiles

  3. Loading & unloading zones

  4. Construction corridors

  5. Communities next to mining or quarry operations

    AGS Step-by-Step Process — Dust Suppression

    1. Dust Survey & Risk Assessment

    • AGS maps dust sources, road conditions, traffic counts and meteorology.

    • Baseline PM10 / PM2.5 measurements recorded.

    • Sensitive receptors identified (workers, villages, schools).

    2. Product Selection

    AGS uses different AGS TotalDust™ chemistries depending on soil type:

    • AGS TotalDust™ Polymer Binder – long-term sealing

    • AGS Hygro-Lock™ – moisture retention for clay/silty soils

    • AGS Stockpile Shield™ – for stockpiles and exposed materials

    • AGS NanoBind™ – deep penetrating fines-binding agents

    3. Surface Preparation

    • Road trimmed to reduce loose fines.

    • Berms removed to allow even treatment.

    4. Application

    • Applied using water carts fitted with AGS dosing units.

    • Achieve uniform coverage across full lane width.

    • Application rates adjusted based on CBR, fines content, and traffic volume.

    5. Operational Monitoring

    • PM monitors installed to capture real-time dust reduction.

    • Road conditions observed multiple times a day during initial implementation.

    6. Conditioning & Setting

    • Product binds dust particles and creates a semi-flexible surface matrix.

    • Traffic helps embed and compact the treated layer.

    7. Re-application & Maintenance

    • Low-traffic roads: re-application every 6–12 months.

    • High-traffic haul roads: every 3–6 months (depending on rainfall).

    • AGS provides a custom O&M schedule.

    8. Compliance Reporting

    • AGS provides documentation for environmental regulators and mining safety authorities.

EROSION CONTROL & SEDIMENT MANAGEMENT

Using AGS EarthGuard™ Systems

AGS delivers preventive and remedial erosion control solutions designed for:

  • embankments

  • disturbed soils

  • road batters

  • drainage channels

  • mine rehabilitation areas

These systems combine chemical surface bonding, slope reinforcement, and optional vegetative or geotextile integration.
This approach is widely adopted in Australian civil and mining rehabilitation programs.

AGS Step-by-Step Process — Erosion Control

1. Erosion Hazard Assessment

  • Map slopes, run-off patterns, rainfall intensity and soil type.

  • Identify high-risk erosion zones.

2. Solution Selection

Depending on severity:

  • AGS EarthGuard™ Surface Binder – prevents surface wash

  • AGS HydroCover™ – hydromulch/hydroseed for vegetation

  • AGS GeoArmor™ – geotextiles, meshes, erosion blankets

  • AGS SedimentShield™ – for drainage lines or high-flow zones

3. Earthworks & Surface Preparation

  • Grade slopes to stable angles.

  • Bench steep slopes if necessary.

  • Remove loose debris.

4. Binder Application / Armouring

  • AGS EarthGuard™ spray creates a bonded crust that resists rainfall and sheet-flow erosion.

  • Applied via spray systems or hydroseeder depending on surface area.

5. Structural Reinforcement (if required)

  • Install geotextiles, mats, or geo-cell structures.

  • Anchor edges and overlaps.

6. Drainage Integration

  • Add diversion banks, check dams, silt traps and sediment logs.

  • Ensure controlled flow direction.

7. Vegetation Establishment

  • Apply AGS HydroCover™ blend (seed + mulch + binder) to regenerate natural cover.

8. Monitoring & Maintenance

  • Regular visual inspections (monthly or seasonal).

  • Reapply binders after extreme rainfall if needed.

  • Maintain drainage and traps.
