With 27 years' experience in the asphalt industry, National Asphalt has emerged as a key player in the South African arena. National Asphalt commenced operations during the latter part of 1988 operating from premises alongside Sterkspruit Crushers in Cliffdale, approximately 30 km from central Durban. Whilst the operations have grown exponentially over the past years, the Cliffdale plant is still a key static plant within the national stable. Over the years the company has operated throughout South Africa and Lesotho. After initially focusing on the KwaZulu-Natal market, the acquisition by Raubex in 2007 accelerated its growth and its footprint in the South African market.

The acquisition of Akasia Road Surfacing in the latter part of 2007, together with the acquisition of a major shareholding in Shisalanga in 2014 and recently the formation of Belabela Asphalt in Botswana, has positioned the company uniquely to take full advantage of all opportunities within the Southern African road markets. Together, with having a number of fixed plants located in strategic locations, the company has focused on investing in a number of state-of-the-art mobile plants including three fully mobile recycling plants built by Comar, a sister company within the Raubex Group. Having led the field in mobile recycling, National Asphalt has an advantage that places it at the forefront of the industry enabling it to carry out contracts anywhere in the country.

Since it opened in 1998, Shisalanga has grown from strength to strength and now not only manufactures and paves hot mix asphalt, but produces a high quality coldmix asphalt, lay surface and slurry seals, crack sealing, deep and shallow milling, insitu-stabilizing and hydro surface treatment.

Shisalanga has become a leader in new innovations, leading the way with products such as steel slag manufactured asphalt, a first in South Africa. This product is the preferred aggregate used for asphalt manufacture on the busiest highway in South Africa, the National Route 3 (N3).
