Different Types of Aggregates Used in Road Construction: Classification of aggregates based on Grain size: 1.Fine Aggregate: The aggregate with grain size below 4.75 mm is termed as fine aggregates.. The percentage of all type deleterious materials in fine aggregate should not exceed 5 %.
Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of various coarse aggregates given below: Fine gravel: 4mm – 8mm.
Laying Road Base Material. The crusher run road base to be placed on top of the sub base shall consisting of crushed aggregate laid in layers each of thickness not exceeding 200mm and to give the specified total compacted thickness and width, correct line and levels shown in road construction drawings.
Aggregate size 20mm used in RCC structure, 40mm aggregate size used in PCC structure or mass concreting and 75 mm and more size used in retaining wall construction. Size of aggregate used in PCC This is best, perfect, ideal and standard size of aggregate used in PCC like construction of PCC pavement, road, walkway or driveway.

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.
Crushed Stone Sand. It looks like gravel and feels like gravel. But unlike gravel, crushed stone sand is a natural but commercially created resource that is made from crushed minerals, such as granite or limestone. Crushed stone sand is commonly used for road construction, and is widely known as a low-cost, high-value commodity.
Building Materials. Building materials cover a wide range of construction products like concrete, sand, clay, bricks, plaster, adobe, tiles, reinforced concrete, shotcrete, aggregate, wattle and daub, lath, gypsum plaster, plaster of paris, mortar, slab, siding, clapboard, asphalt tile, plastering sand, UPVC windows, asbestos, marbles, steel etc. Buildings materials is an umbrella term that is
Sand in Road construction in the SADC Region is to provide practitioners with a good understanding of the engineering properties of one of the most abundant, naturally occurring materials found in the Southern African region – sand – so as to facilitate the more wide-spread use of this ubiquitous material in the construction of low volume

Current practices in terms of sustainable highways. In Europe, 277.3 million tons of asphalt were produced in 2013 for the construction of roads (source: 5924. European Asphalt Pavement Association). Asphalt is produced at high temperatures (160 – 180°C). Per ton of asphalt, 275 MJoule is needed, which implies a consumption of 76 billion
We have the capability to produce world class construction material, especially aggregate for asphalt projects, supported by top of the line machinery and equipment. Our quarry is located in the leading aggregate production zone of the Middle East, Kadra, RAK, UAE.

Road Aggregate 101: Specifications and Uses Gravel – unconsolidated rock fragments formed as a result of the weathering and erosion of larger rocks. PennDOT requires gravel used for road construction to be durable with a minimum of 85% crushed particles and at least two faces resulting from fracture.
Operating throughout Scotland, central, eastern and northern England and Wales, our quarries produce crushed limestone, granite, basalt, sand & gravel for a variety of uses in the construction industry. We also supply high PSV (Polished Stone Value) stone, sub-base materials and sands for the road construction industry.
Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway. The aggregates to be used in road construction, particularly
Aggregate size 20mm used in RCC structure, 40mm aggregate size used in PCC structure or mass concreting and 75 mm and more size used in retaining wall construction. Size of aggregate used in PCC This is best, perfect, ideal and standard size of aggregate used in PCC like construction of PCC pavement, road, walkway or driveway.
Aggregates are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix. On average, 38,000 tons of aggregates are necessary to construct one lane mile of interstate highway.
Three types of aggregates were used in this study which include natural sand as fine aggregate (NFA), coarse aggregates with grading of 4.75–20 mm were dolomite as natural (NCA) and the crushed concrete rubble as (RCA) which were collected from fifteen different sources of demolished buildings and landfill locations then crushed using a Hartle PC-160 mobile impact crusher shown in Fig. 1
