An acceptance test for bitumen for rolled-asphalt wearing course
Trrl Lr 777 A technique in which cores of different wearing-course materials could be inserted in road surfaces was developed to evaluate the performance of a range of bitumens under traffic. At the same time a number of laboratory tests were carried out on the bitumens and it was found that permittivity (dielectric constant) correlkated best with development of texture in rolled asphalt, an…
Improving Adhesion Characteristics of Bituminous Mixes by Washing Dust-Contam…
Whether the engineering characteristics of bituminous mixes (especially their resistance to moisture effects) can be improved by washing the coarse aggregates and mixing the coarse and fine aggregates separately has been investigated. Results indicated that the washing of the coarse aggregate was most effective with the weaker aggregate. Washing the coarse aggregates generally improves the stre…
