Abstract
Various methods were used to design asphaltic concrete,
hot rolled and mastic asphalts. Asphaltic concrete and
mastic asphalt were designed principally using the
Marshall procedure, while hot rolled asphalt was designed
according to BS 594 and a method proposed for gap-graded
mixes. A typical surface dressing design was also carried
out for a lightly trafficked road suitable for Northern
Nigeria. The optimum binder content and other design
parameters were determined for the surfacings investigated.
Some of the values obtained were 6.9%, 6.86% and 13.7% as
binder content for asphaltic concrete, hot rolled and
mastic asphalts respectively. 17.2kN, 8.4kN and 10.2kN for
stability. 4.0%, 5.2% and 3.0% were obtained as voids in the mix.
The analysis and cost estimates of test results showed
that it would cost N3G5.17 to lay a m3 of asphaltic
concrete against N341.70 for hot rolled asphalt. It will
cost 84.86 to apply surface dressing on a m2 of road
surface
