ADDITIVES IMPROVE ASPHALT LAYING METHODS

The article describes improvements resulting from the use of additive materials in asphalt and bituminous mixes. The use of the following additive materials is evaluated - rubber, glass waste, plastic waste, epoxy resins, asbestos fibre, cement/hydrated lime, kaolin clay and, anti-stripping agents. Although there are advantages in using such additive materials to strengthen bituminous mixes, the additional cost incurred must be taken into account. The inclusion of additive materials could result in a reduction in bituminous materials consumed, as an additive which results in a 20% cost increase can offer a 50% increase in useful life. /TRRL/
