Cement-stabilized macadam is the most widely used road base material in road engineering. _ macadam road surfaceother pavement structures shall be substitute by the engineer as per site condition. The thickness of a single compacted Wet mix macadamWMM layer shall not be less than 75mmwhen vibrating or other approved types of compacting equipment are used the compacted depth of a single layer of the. As work proceeded on the National Road the technique advanced by MacAdam was put to use giving the new road a very solid foundation that could stand up to considerable wagon traffic.

The authors prepared polyester fibers with diam-eters of 20 35 70 and 105 μm and added them to cement-stabilized macadam. Cement-stabilized macadam is the most widely used road base material in road engineering. The base course binder course is a load spreading layer spreading the load imposed on the wearing course surface course over a wider area of the road base Base course binder course is most commonly a bituminous material can be either Hot rolled asphalt or dense bitumen Macadam asphalt concreteThis is a strengthening layer of the pavement and should be at least 40 mm.

McAdams road cross section was composed of a compacted subgrade of crushed granite or greenstone designed to support the load covered by a surface of light stone to absorb wear and tear and shed water to the drainage ditches.
