Wet mix macadam (WMM) is a type of road construction material that consists of a mixture of crushed aggregates, water, and binding material like bitumen or cement. Here are the general steps on how to make wet mix macadam:
Prepare the base: The base of the road must be properly prepared before laying the WMM. It should be compacted and leveled to create a stable foundation.
Select the aggregates: The aggregates used in WMM should be of a specified size and quality to ensure proper compaction and durability. The aggregates are usually a mix of crushed stone, gravel, or sand.
Mix the aggregates: The aggregates are mixed in a pug mill or mixing plant with water and binding material, such as bitumen or cement. The amount of water and binding material will depend on the specific requirements of the project and the type of WMM being used.
Transport the mix: Once the WMM mix is prepared, it is transported to the site in trucks or dumpers.
Lay the WMM: The WMM is laid on the prepared base using a motor grader. The thickness of the WMM layer can vary, but it is usually between 75-100 mm. The WMM layer is then compacted using a roller to achieve the desired density and smoothness.
Cure the WMM: The WMM is allowed to cure for a few days before the final asphalt or concrete layer is added on top.
Atlas is manufacturer and exporter of wet mix macadam plants. We manufacture the same in different models and capacities ranging from 100 to 300 tph.
It’s important to follow the specific guidelines and specifications provided by the project engineer to ensure proper construction of WMM.
