Asphalt composition with holding and masking agents

Abstract

Two specific types of ingredients are added to cold or hot melt asphalt or coal tar for the dual purposes of holding, reducing or complexing the obnoxious and toxic odors from asphalt while at the same time allowing a pleasant masking fragrance to predominate. The holding agents consist of various organic compounds which can bond or complex with and effectively hold onto other molecules. Typical complexing agents include dialkylgylcol alkyl ethers and dialkylphthalates. Typical fragrances include natural and synthetic oils or extracts such as lemon oil, orange oil, peppermint, spearmint, cinnamon, bubble gum and most other common fragrances. The concentrated extracts of fragrances consist of natural and synthetic materials having glycols, glycol ethers, alcohols, esters, aldehydes, ketones, and other compounds which can simply mask the obnoxious odors.
