Soil Compaction Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs …
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Strength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forces. Elasticity measures the "stretch" in a particle. High strength and elasticity are desirable in aggregate base and surface courses. These qualities minimize the rate of disi ntegration and maximize the stability of the compacted material.
Gravel Road Construction. Although gravel road construction can be done anytime on any surface, a smooth, long-lasting roadway requires the right process. Like any other building project, a gravel road starts with the foundation. The other three stages are sub-grade material, sub-base …

The field density test (road base) testing is it right thing 250mm deep 150mm dia hole have to dig by hand with chisel and hammer by the human? the technology is up on the top, but this test method is look like back to stone age.
Road Base is a blend of Gravel and fine material which, when compacted will form a hard surface with a high level of mechanical strength. This can be used as the main layer for laying the groundwork of creating a road. Our range of road base is of a high quality and is supplied in bulk quantities (Minimum 20 Cubic Meters) to any location in UAE
Steps in Bituminous Road Construction 1. Preparation of the existing base course layer. The existing surface is prepared by removing the pot holes or rust if any. The irregularities are filled in with premix chippings at least a week before laying surface course.

layer of bitumen and aggregate, either as a single aggregate on bitumen, or a mixture of stone and aggregate known as asphalt. It may also be that the pavement is designed to be rigid and would usually comprise a thin lean mixed concrete sub-base layer overlain by a thicker concrete base layer.
Construction companies and contractors rely on aggregate and sand suppliers in UAE for their building material needs. Many aggregate suppliers operate quarries to ensure steady supply of crushed rock materials. They offer a wide range of crushed rock products such as granite, limestone and grit stone.
1.1 This specification covers quality-controlled graded aggregates that, when hauled to and properly spread and compacted on a prepared grade to appropriate density standards, may be expected to provide adequate stability and load support for use as highway or airport bases or subbases.
Chapter 3 Pavement Patching and Repair General The roadway is the paved or otherwise improved portion of a public highway ordinarily used for vehicular travel. The roadway surface is normally classified as rigid (consisting of Portland Cement Concrete) or flexible (consisting of asphaltic materials).
A wide variety of aggregate options are available to you, such as gravel & crushed stone, sand, and other natural stone. There are 36 aggregate suppliers, mainly located in Middle East. The top supplying country is United Arab Emirates, which supply of aggregate respectively.
