General Asphalt Recommendations - Asphalt, Concrete and ...
www.morrisandperry.co.ukThe asphalt layers must be compacted while the material is at an appropriate temperature. Recommendations for temperatures and for laying and accuracy of finish are given in British Standard 4987 for macadams and BS 594 for hot rolled asphalt. In view of the skill needed in laying asphalt materials it is
Volumetrics in Asphalt Mixtures
www.co-asphalt.com= (Vol. of air + effective asphalt) (Bulk vol. of compacted mix) = (Va + Vb - Vba) / Vmb X 100% = (Va + Vbe ) / Vmb X 100% - Adequate VMA is needed to ensure that adequate amount of asphalt could be added to the mixture without overfilling the voids and resulting in asphalt bleeding.
