Crushed aggregate subbase/base layers function primarily as support of the pavement and provide additional load distribution There are two methods of material placement The requirements for compaction eveness levelling and uniformity are much higher than for embankment layers Over compaction and aggregate crushing needs to be avoided.
types of asphalt emulsion ma y be used if experience has proven that satisfactory performance will result Othe r emulsions which can be used can be found listed in ASTM D3628 Aggregate The aggregates shall be crushed stone crushed slag crushed gravel or sand con forming to the requirements of the appropriate ASTM specifications.
Aggregates Breedon is a leading producer and supplier of bulk aggregates in Great Britain crushed rock in a variety of grades bagged aggregates decorative aggregates and sand gravel Operating throughout Scotland central eastern and northern England and Wales our quarries produce crushed limestone granite basalt sand gravel for a
Cold Mix Aggregate The type of mix aggregate used in open graded mixes must meet certain requirements of shape size gradation cleanliness and surface properties The aggregate should have a maximum size of mm for base courses mm for surface courses and have between 0 and 10 passing the mm sieve size with no more than 2
The rock is crushed and compacted to provide a more solid surface The rock size gradations are shown in the specifications 4 2002A 11 Decomposed Granite Decomposed granite is used similarly to gravel mulch The material is more complex to construct as it needs to have solidifying emulsions and layered construction to achieve a solid surface.

Although limestone and crushed gravel both performed well Abbas recommended using aggregate with absorption below 3 percent otherwise you will need more asphalt content They will continue to use PG58 28 and recommended a
19 12 2013 Bitumen emulsion cold mixtures are more and more used for low traffic pavements In comparison to hot mixtures they present many advantages such as reduction of energy consumption cost savings and low environmental impact 1 2 .Cold mixtures are composed of aggregates 90–95 in weight and bitumen emulsion.
durability Crushed aggregates are recommended The recommended minimum amount of fractured faces is 60 75 percent Select the Type of Emulsion In selecting the type of emulsion consideration must be given to the aggregate type and gradation and climatic conditions Medium set emulsions are normally used for
