LBS Asphalt

Introduction To Labour Intensive Road Surfacing

LBS Asphalt (labour based road repair and surfacing) is a cold asphalt formulated mixture of inert fillers, bitumen extenders and binder enhancers designed to be blended with selected aggregates and water.
Manufactured by Road Material Stabilisers (Pty) Ltd, it was originally developed in 2004 in response to a request from the Road Agency Limpopo’s Gundo Lashu project team which included representation from the International Labour Organisation and BKS Consulting Engineers. The brief was to design an asphalt seal to the highest possible recognised standards whilst maximising the labour component. A product was required that would be suitable for implementation and inclusion in poverty relief or EPWP programmes where contractors and their labour force have little or no prior experience and skills.

Key Principles​

In order for this to be achieved the LBS Asphalt system was designed specifically focusing on 6 key principles:

1. Job Creation

The system has been deliberately designed to maximise the labour component

2. Quality

The asphalt premix meets the necessary design criteria, for a fine or medium continuously graded asphalt as defined by both COLTO and TRH8.

3. Cost Effectiveness

LBS asphalt offers a significant cost advantage over pre-mix bagged cold asphalt.

4. Simplicity

All equipment required on site for the mixing of the asphalt components has deliberately been kept as basic as possible

5. Training & Technical Support

SAQA accredited training, provided in partnership with the South African Foundation for Empowerment Training & Innovation

6. Sustainability (Exit Strategy)

A program has been designed to ensure that community-based asphalt plants and road repair teams are developed into structured, business enterprises.

LBS Projects

The LBS Asphalt technology has been used by numerous municipalities and road authorities across South Africa since 2004. The technology has been approved as an asphalt surfacing option for SANRAL Southern & Western Region’s Contractor Development Programs on various projects in the Eastern & Northern Cape.
The ultimate goal of the LBS Asphalt system is to create an environment for community empowerment by stimulating the creation of new jobs, converting them into sustainable businesses, turning job seekers into job creators and adding real value to road authority, road repair and maintenance programs.

LBS Applications

  • Rural and residential roads
  • Road maintenance and repair
  • Labour intensive road construction
  • Poverty relief programmes

Advantages of using LBS


Mix design

Conforms to South African TRH8

Exceeds design criteria

For E4 classification of roads (TRH8)​

Minimal disruption to traffic

Cold Asphalt

No heating required

Easy application

No specialised equipment necessary

Ideally suited to labour based construction

Cost effective

80% of the final mix is sourced locally thereby reducing transport costs significantly

Environmental Impact of using LBS

LBS is environmentally friendly, it has no long-term adverse impact on the environment and is safe to handle. It is non-toxic and non-hazardous.
