Thinlays are thin asphalt overlay mixes typically designed to be placed as thin as 5/8 of an inch. Section N10 is a 4.75 mm nominal maximum aggregate size (NMAS) stone matrix asphalt (SMA) mix with a PG 76-22 binder. The Thinlay in N10 was placed at a thickness of 0.8 inches. Section N11 is a 4.75 mm dense-graded mix with a PG 67-22 binder.

This section lists the standard HMA mixes used in Washington State both today and prior to changing from the Hveem mix design method.

The gradation of the aggregate determines the aggregate surface area, and together with asphalt content and absorption they determine the amount of free asphalt available to coat the aggregates. The volumetric properties of the combined aggregates and the asphalt mixtures are respectively tabulated Table no 3.2.1 & 3.2.2.

For the above reasons, aggregate gradation and size is closely controlled in asphalt mixes. Specific size ranges of aggregates are commonly separated and stockpiled, allowing blends to be created with specific gradations. Aggregates can also be crushed to reduce the maximum size of larger particles.

According to the difference of the maximum particle size of the mixture, asphalt concrete can be divided into 4 types: coarse-grained (35-40mm), medium-sized (20-25mm), fine-grained (10-15mm) and sand (5-7mm). According to the different gradation of mineral aggregate, asphalt concrete can be divided into 3 types: dense graded asphalt concrete ...

Asphalt cement of 60170 penetration grade and gran­ ite aggregates, the only type of aggregate available in Singa­ pore, was used. The binder content of each mixture was the optimum asphalt content by weight of total mix determined by using the Marshall method of mix design (17). Wl and W3 were dense-graded mixes with a nominal top size of 19

For the above reasons, aggregate gradation and size is closely controlled in asphalt mixes. Specific size ranges of aggregates are commonly separated and stockpiled, allowing blends to be created with specific gradations. Aggregates can also be crushed to reduce the maximum size of larger particles.

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. Coarse aggregate: Size: Fine gravel. 4mm – 8mm. Medium gravel. 8mm – 16mm. Coarse gravel.

AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

The maximum particle size is important because it controls the appropriate lift thickness of the mixture placement. For good paving results, the lift thickness of a dense-graded asphalt mix should be 2½ to 3 times the maximum aggregate size or 3 to 4 times the nominal aggregate size in the mix.

Asphalt Emulsion - A combination of asphalt, water, and small amount of an emulsifying agent processed in a colloid mill. The asphalt is sheared into tiny droplets and the emulsifier (a surface-active agent) keeps the asphalt droplets in a stable suspension and controls the …

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.

Lift thickness governs aggregate size. Minimum lift thickness should be at least 3 times the nominal max. aggregate size to ensure aggregate can align themselves during compaction to achieve required density and also to ensure mix is impermeable. The maximum lift thickness is dependent also upon the type of compaction equipment that is being used.

Separate the aggregates by dry sieving into the desired size of the fraction. Weigh in to separate pans for each test specimen the amount of each size of fraction required to produce a batch that will result in a compacted specimen of height 63.5 ± 1.3 mm which is generally of 1.20kg including asphalt percentage.

"Putting down a rock base before placing the hot mix is critical," Prather says. "The size or thickness of the rock makes a difference. We use 2-inch (top-size) rock—as big as your fist. The 2-inch rock sinks into the subgrade and stabilizes the earth," adds Prather. Proper drainage. Another key …
