Wet Mix Macadam Rate per Cubic Meter in 2022

Wet Mix Macadam Rate per Cubic Meter, Price, weight per cum and Specification

In wet mix macadam, the aggregates and binding materials are premixed in a batching plant and then laid on the site. WMM is a base course to the pavement. In this article, we will know how to calculate the wet mix macadam rate per cubic meter.

The traditional Water Bound Macadam method is very time-consuming. Further, segregation of aggregates takes place which results in a non-uniform surface. To overcome this a more durable pavement construction technique is devised which is called Wet mix macadam.

Wet mix macadam has many advantages over Water Bound Macadam. For example, it has a superior gradation of aggregates, a faster rate of construction, a higher standard of densification with less amount of water etc.

The base thickness of the single compacted layer of Wet Mixed Macadam (WMM) should not be less than 75 mm. It is laid in layers of 75 mm or 100 mm as per the given thickness and can go up to 200 mm provided appropriate compacting equipment is used.

Rate analysis for Wet Mix Macadam

Rate analysis of Wet Mix Macadam consists of determining the total quantity of material, cost of material, machinery/plant charges and labour charges.

Weight of WMM per cum

Weight of Wet Mix Macadam per cum depends on the unit weight of the aggregates used. Generally, the unit weight of WMM per cum is 2200-2300 Kg.

What is wet macadam mix?

In wet mix macadam, the aggregates and binding materials are premixed in a batching plant and then laid on the site. The base thickness of the single compacted layer of Wet Mixed Macadam (WMM) should not be less than 75 mm.

What is density of WMM?

Wet Mix Macadam (WMM) has bulk density of 2200-2300 Kg per Cum.

What is meant by WMM Road?

The roads in which met mix macadam (WMM) is used as the base course is known as WMM Roads. In Wet mix macadam roads, aggregates and fine material are mixed with water in batching plant and then laid on the site.

What is the difference between water bound macadam and wet mix macadam?

The traditional Water Bound Macadam method is very time-consuming. Further, segregation of aggregates takes place which results in a non-uniform surface. Wet mix macadam has many advantages over Water Bound Macadam. For example, it has a superior gradation of aggregates, a faster rate of construction, a higher standard of densification with less amount of water etc.

How do you make wet macadam mix?

In wet mix macadam, the aggregates and binding materials as per the IRC and MORTH Specification, are premixed in a batching plant with water and then laid on the site in desired thickness.
