Document Type and Number:
Japanese Patent JP3957389
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an asphalt-emulsifying agent capable of improving the adhesivity of asphalt to aggregates and capable of largely shortening a working time and a road-blocking time due to a road construction, because the curing of asphalt is finished at least within 3 hr after application, when a pavement work is carried out using the asphalt-emulsifying agent.
SOLUTION: This asphalt-emulsifying agent comprises 40-80 pts.wt. of asphalt, 60-20 pts.wt. of water, 0.01-10.0 pts.wt. of a surfactant, and 0.01-5.0 pts.wt. of a performance-improving agent comprising tall oil fatty acid and/or a tall oil derivative having an acid value of 50-300 and an iodine value of 5-200.
