Deco® granite comes in 3 colours, brown, pink and gold, and should be stabilised with cement at 5%, or 1 bag of off‐white cement per tonne of Deco® Granite for pedestrian use, or 10%, or 2 bags of cement per tonne for driveways.
20/12/2011 · Crushed stone may also be made from granite and other rocks. Dense grade aggregate, or DGA, also known as crusher run, this is a mixed grade of mostly small crushed stone in a matrix of crushed stone powder, graded to produce low void content and maximum weight when compacted.
mixing is usually employed only when very coarselygraded aggregates are employed. Both of these grades may be used for surface treatment work, as may RC5. When used for this purpose, cover aggregate should follow the asphalt spread as closely as possible. RC4 and RC5 are both well adapted to stationary or travelplant

18/08/2020 · Wet Mix Macadam construction is an improvement upon the conventional Wet Bound Macadam (WBM) and is intended to be as an alternative and more durable pavement layer in roads and highway works.. It generally consists of clean, crushed, graded aggregates premixed with other granular materials and water and rolled to a dense mass on a prepared surface.
Classifiion of Aggregates Based on Size Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classifiion of aggregates based on size: Aggregates are classified into 2 types according to size

OpenGraded Mixes. Unlike densegraded mixes and SMA, an opengraded HMA mixture is designed to be water permeable. Opengraded mixes use only crushed stone (or gravel) and a small percentage of manufactured sands. Opengraded mixes can be used in these ways: Permeable pavement. An opengraded mix is used for the entire pavement hard surface.
Graded base is a construction aggregate typically composed of crushed rock capable of passing through a 20millimeter (3⁄4 in) rock screen.

Specifically, opengraded mixes and low asphalt binder content mixes are particularly prone to segregation. Stockpiling. If aggregate is loaded on top of a conical stockpile then larger aggregate sizes are more likely to roll to the outside and bottom. Asphalt plants.
DenseGraded Mixes. A densegraded mix (Figure 1) is a wellgraded HMA intended for general use. When properly designed and constructed, a densegraded mix is relatively impermeable. Densegraded mixes are generally referred to by their nominal maximum aggregate size. They can further be classified as either finegraded or coarsegraded.
