"BLACK SEAL" AND ITS USE FOR FINISHING OR RESTORATION ASPHALTIC SURFACES

EL SELLO NEGRO Y SU EMPLEO PARA TERMINACION O RESTAURACION DE LAS SUPERFICIES ASFALTICAS

The construction of bituminous road surfaces presents many complications. Causes producing defective surface textures in pavements are specified and the use of coatings of the "black seal" type to obtain a better appearance, sometimes increasing the durability of asphaltic concrete covers is suggested. Data are presented on experiments with a special type of Black Seal on two roads of Santiago de Chile; one of them presented little surface cracking after approximately ten years of use, while the other, used for more than 25 years, had surface cracks besides some deep ones and holes, which were previously repaired. /TRRL/
