mechanical equipment, approved hand spreading methods may be used. COMPACTING Aggregates are required to be immediately compacted to a minimum of 100 % of the maximum dry densities in accordance with AASHTO T 99. Compaction equipment is required to be in accordance with Section 409.03(d). Density of the compacted aggregate is determined in


Aggregates are divided into natural aggregates and artificial aggregates. According to the degree of thickness, they are divided into coarse aggregate (crushed stone or gravel) and fine aggregate (sand). Due to the non-renewable resources, the mining of natural aggregates is increasingly restricted.


Crushed Aggregate Base Coarse (Compaction Gravel) shall consist of one or more courses or layers of coarse aggregate, either crushed gravel or crushed stone, fine aggregate and binder or filler blended as necessary to produce an intimate mixture of the required gradation and stability. Requirements: The aggregate shall consist of hard, durable ...


this report is on aggregates that generally are used in applications that require durable stone, that is, stone that is resistant to mechanical breakdown through such things as freeze and thaw action and stone-to-stone grinding caused by loads on the aggregate. Stone of this nature, such as is used for aggregate in large concrete structures and


CRUSHED STONE PLANTS A crushed stone plant differs somewhat from a sand and gravel plant. Raw material, of various sizes, is brought from a quarry, to a primary crusher, by haul units. Some primary crushers are fed by wobblers, which are chain driven conveying systems, with eccentric rollers.


A.A. Jimoh and S. S. Awe (2007), A study on the influence of aggregate Size and type on the compressive strength of concrete presented in his research that the effect of crushed stone sand as fine aggregates causes of flexural strength increase than the concrete with natural sand but the values decreases as percentage of crusher dust increases ...


Mechanical Concrete® is a way of binding crushed stone aggregates together into a load bearing cellular building unit. The Mechanical Concrete® unit can support compressive loads and resist lateral soil pressure. It is basically a compressive material. Mechanical Concrete® confines the stone within a Mechanical Cement®, stay-in-place, cylinder.

Mechanical Concrete® is a breakthrough, patent protected, construction technology. It utilizes a cylinder made from waste auto tires to confine and integrate crushed stone, or other natural and recycled aggregates, into a permanent stone building unit. The result is a strong, economical construction and maintenance product for low volume roads.


Mechanical Concrete® solves a variety of low volume road problems: it is a completely new way to more effectively use crushed stone, natural and recycled aggregates and to stabilize indigenous materials. Engineering Specs Mechanical Concrete® offers a minimum 200 pounds per square inch (14.4 tons per square foot) working strength.
