Continuous Mixing & Paving

The RapidMix 400CW is a continuous mixing plant which produces high quality, controlled mixtures for utilisation in a range of civil engineering applications -from airport runways and dam construction to soil stabilisation and the treatment of contaminated land.

The RapidMix 400CW provides a cost‑effective solution to projects where compliance with technical specifications coupled with demand for high‑volume output is critical. Blending of materials is done at rates of between 300 and 400 tons per hour. The mobile nature of the plant, combined with its technologically advanced design allows KMC Construction to meet the high-volume demand on projects.

The final aggregate produced with the RapidMix 400CW is transported to an aggregate paver which then spreads and places the material to the required width and grade for the roadway being constructed. The remainder of the process follows conventional methods.

There are three distinct advantages when using the in‑plant process:

  1. It results in improved workability and lead times as the material is placed at the precise optimum moisture content (OMC).

  2. There are no windrows (i.e. near zero waste of expensive material).

  3. The consistency of the blended material, mixed with the in‑plant method, cannot be matched with conventional methods. This is critical to the durability of the road.

Overall, the quality of the product is improved with greatly reduced lead times also being achieved.

APPLICATIONS:

  • Blending of multiple aggregates for road construction

  • Stabilising of aggregates with cement and/or bituminous emulsion to OMC for road subbase and bases

  • Mixing of G1 material to OMC for road bases

  • Roller‑compacted concrete (RCC)

Bitumen Stabilised Materials

Ever increasing economic pressure and environmental awareness drives the development of more effective technologies for road construction and rehabilitation. This has seen an increased interest in pavement rehabilitation using in‑situ stabilisation with bitumen products. Stabilisation with bitumen provides environmental benefits such as low temperature construction and the use of existing material in the pavement structure.

KMC Construction’s continuous mixing plant process positions us as a market leader in the application of bitumen stabilised materials (BSM). In‑plant mixing method is a superior process. The in-plant treatment of materials results in far greater consistency and homogeneity compared to other conventional methods of mixing and blending of material. KMC Construction has successfully proven these results on a road rehabilitation project, through on-site testing and independant tests performed by certified laboratories, in close collaboration with Pavement Engineers.

The efficiency of this method of construction means that clients are able to build more kilometres of road with the same budget. Roads constructed using BSM layers are also far more durable due to the high level of consistency achieved using this method.

Asphalt Paving

The responsible use of fossil fuels and associated binder products used by the asphalt industry drives the need for constant innovation. Continuous research into engineering stronger asphalt pavements which are more economical and sustainable also results in the necessary changes to the methods of construction required. As these changes occur, we will ensure adaptation through the use of the latest technology of asphalt pavers in our fleet. Incorporating 3D survey technology we are able to ensure that the best quality, rideability, levels and grades are achieved in the roads we construct.

Slipform Concrete

KMC Construction possesses a wealth of experience when it comes to slipform paving. Starting from smaller jobs, using medium-sized pavers on our infrastructure projects and expanding to major projects, using specialised slipforming techniques, for major contractors. Through the amalgamation of the slipform operation from another major contractor, KMC Construction was able to procure the machines, equipment and teams involved in all their past successfully executed slipform work. We now boast the largest complement of slipform pavers in the country allowing us to offer a broad range of products including, but not limited to: roads; runways; track slabs; barriers; parapets; channels; sidewalks; and drains.
