Quantity of the WBM is generally measured in cubic meters while that of the WMM in square meters. What is GSB material? Granular Sub Base(GSB) is natural or designed construction material,

vegetation.Road area is prepared for the finished formation level. This is usually done using a manually and mechanically like tractor shovel and Kankar road. WBM Road is laid as layers of about 10cm and may disintegrate immediately under traffic. Read More Wbm RoAd. Bituminous roads. Bituminous roads are prevalent roads around the world.Disadvantages of Bituminous Road : The viscosity of the bitumen and aggregate mix plays important role in defining the performance of bituminous road. If the bituminous material is used in excess than the value for given mix,

In the construction of the WBM road it effects the performance of the bituminous road.

Preparation of The Foundation. The foundation for receiving the new layer of W.B.M may be either the subgrade or subbase course. This foundation layer is prepared to the required grade and camber and the dust ...In this video,

since road construction techniques are similar throughout the world light graded aggregates premixed with other granular materials and water and rolled to a dense mass on a prepared surface.GSB full form in road construction | DBM | WMM | WBM full form in road construction. September 2 the maintenance cost is high. The overall life span of Water Bound Macadam Road is less. A high probability of danger to traffic and inconvenience is there if these roads do not receive proper maintenance. This leads to yielding and softening of the subsoil as these ...Construction Steps of WBM roads Step 1. The foundation for receiving the new layer of WBM roads may be either the sub grade or sub base or base course. This layer is thus prepare by scarifying and filling the depressions and patching the pot holes,

The following steps are adopted for the construction of WBM roads: 1. Preparing the foundation for receiving the WBM course. The foundation supporting the layer of WBM is either the subgrade or sub-base course. It is prepared to the required grade and camber. It is cleaned of all the dust particles and loose ...Construction Procedure of WBM road,

Salient Features of WBM Roads • WBM means Water Bound Macadam. • The word Macadam comes from the name of Scottish Engineer John L. Macadam.GSB uses to prepare sub-base courses for road construction. Granular sub-base is the large size of gravel or boulder. The size of GSB is up to 65mm. DBM full form in road construction stands for dance bituminous macadam. WMM full form in road construction stands for wet mix macadam. WBM full form in road construction stands for water-bound macadam.Figure 2 : road construction 2.1 Types Of Road Constructio (Highway Construction) : 1) Earth road and gravel roads 7. 2) Soil stabilization roads 3) Water bound macadam road(WBM) 4) Bituminous or black-top road 5) Cement concrete road 2.1.1Earth Road And Gravel Road:- An earth road is cheapest type of road prepared from natural soil.5. WBM Roads. Water Bound Macadam (WBM) roads contain crushed stone aggregate in its base course. The aggregates are spread on the surface and rolled after sprinkling water. WBM roads provide better performance compared to earthen,

drainage weather conditions in the region etc.WBM Road provides better performance compared to Earthen machine and labour costs Sir John Macadam who initially presented and construct the WBM roads. He was the Surveyor General of Roads in England.Construction WBM road involves the following steps; a. Preparation of Sub-grade. i. Cutting and filling of soil are done according to requirement. ii. The level of the sub-grade is decided by subtracting the total thickness of the pavement from the finished level. iii. Sub-grade is thoroughly compacted using rollers of weight 6 to 10 tones.WBM road construction procedure is given below in detail. The materials are compacted but don't act as monolithic mass and deformation occur from top to bottom. The flexible pavement generally consists following basic layers: subgrade,
