Abstract: Asphalt composition for road pavement, excellent in drying strength, strength after immersion in water, and strength after immersion in petroleum, method for producing same, and road paving method. Composition comprises asphalt, polyester, and aggregate. Polyester has alcohol component-derived constituent unit containing ?65 mol % bisphenol A/alkylene oxide adduct and carboxylic acid component-derived constituent unit containing ?50 mol % terephthalic or isophthalic acid. Composition has softening point of 95°?130° C., hydroxyl group value of 20-50 mgKOH/g, and ratio of polyester resin of 5-50 parts by mass based on 100 parts by mass of the asphalt. Production method comprising mixing asphalt, the polyester, and aggregate at 130-200° C. for ?30 seconds. Polyester resin is mixed in ratio of 5-50 parts by mass based on 100 parts by mass of asphalt. Road paving method comprises laying asphalt composition obtained by production method as set forth, thereby forming an asphalt paving material layer.

Abstract: Provided are an asphalt composition for road pavement, which is excellent in drying strength, strength after immersion in water, and strength after immersion in petroleum, a method for producing the same, and a road paving method. [1] An asphalt composition for road pavement including asphalt, a polyester resin, and an aggregate, wherein the polyester resin is a polyester having an alcohol component-derived constituent unit containing 65 mol % or more of an alkylene oxide adduct of bisphenol A and a carboxylic acid component-derived constituent unit containing 50 mol % or more of at least one selected from the group consisting of terephthalic acid and isophthalic acid and has a softening point of 95° C. or higher and 130° C.

Abstract: The invention relates to optically transparent compositions containing hydrophobic silicone oil and alkyl ether carboxylates that are useful e.g. as a hair treatment composition such as a shampoo. In particular, it provides an optically transparent composition comprising (a) a hydrophobic silicone oil; and (b) an alkyl ether carboxylate derived from alkanols having 6 to 22 carbon atoms; wherein the weight ratio of component (b) to component (a) is in the range of 1:1 to 20:1. The composition preferably also contains anionic surfactants as component (c), the total amount of the components (b) and (c) being preferably in the range of 10-25 wt.-% with respect to the total weight of the composition. The invention also provides a method for preparing the above composition.

Abstract: The invention relates to optically transparent aqueous compositions containing hydrophobic silicone oil and a comparably low amount of wash-active matter, being suitable as a hair treatment composition such as a shampoo. In particular, it provides an optically transparent aqueous composition comprising (a) a hydrophobic silicone oil in an amount of 1-3 wt.-% with respect to the total weight of the composition; (b) a solubilizer for the silicone oil; and (d) an anionic surfactant; wherein the weight-ratio of component (b) to component (a) is in the range of 1:1 to 12:1; and wherein the total amount of the components (b) and (c) is in the range of 10-25 wt.-% with respect to the total weight of the composition. The invention also provides a method for preparing the above composition.
