Wet Mix Macadam Process. Wet Mix Macadam Plant Wet Mix Macadam (WMM) is a relatively newer concept used for laying the base course, which is placed right before the hot mix asphalt during road construction. The binding materials used for the base in case of WMM are prepared in the plant and then brought to the site for overlaying and rolling.

9. The common types of base course materials used in India for the construction of flexible pavement are 'wet mix macadam', 'water bound macadam', soil aggregate mixes and stabilized soil mixes. The flexible pavements of most of the important highways are being constructed these days using WMM as the base course.


In the wet stone method, the stone cladding adheres to the perimeter wall of the building by using wet mix like mortar or adhesives. The wet installation can be performed by two main methods-the Direct Adhesion Method and Spot Bonding Method. Among the techniques mentioned above, the most common and easiest way used is the direct adhesion method.
