Approved Extract

This certificate covers the use of SoilTech MK lll, a non-traditional soil stabiliser, for road construction of base and sub-base layers in all regions of South Africa. SoilTech MK lll is a water based modified bitumen emulsion polymer blend soil bonding agent, which gains strength from mechanical compaction and does not become brittle when cured. SoilTech MK III stabilizers have been purposely designed to penetrate through the road’s base layer, into the sub-base layer, via capillary action. 

SoilTech MK lll, a non-traditional soil stabiliser, is a liquid nano-polymer blend soil bonding agent with elastomers. It is a water based modified bitumen emulsion polymer blend soil bonding agent, which gain strength from mechanical compaction and do not become brittle when cured. It is utilized in base and sub-base stabilization using in-situ materials for both paved and non-paved roads. SoilTech MK lll has been designed with multiple particle-sized nano-polymers coated with micro surfactants in order to lower surface tension and to utilize water as a medium to penetrate the sub-base layer. SoilTech MK lll polymers gain strength from mechanical compaction and do not become brittle when cured. The product penetrates through the road’s base layer into the sub-base via capillary action. The E-modulus property of the elastomer allow the pavement to be flexible under heavy load. The mixing ratios and application rate (mix design) depend on the site specific material and the required road design specifications. SoilTech MK lll is applied at ambient temperature and by use of water tanker trucks. It is applied as a form of bitumen stabilizing material and in accordance with the standard design methods detailed in SANRAL’s manual SAPEM 2014 and SABITA’s TG2 are applicable. Alternatively, Polyroads Pavements (Pty) Ltd.’s guideline documents offer application method.
