The purpose of this study was to evaluate the effects of FAA and gradation on the resulting VMA of certain HMA mixtures The effect of FAA was evaluated using mixtures containing coarse limestone combined with six different fine aggregates Mixtures with three gradations which pass through above and below the restricted zone three different mineral filler contents and four different values

The geometrical morphology influences the slippage and interlock among aggregates for resisting and distributing applied loads In recent years the discrete-element method (DEM) has been employed for simulation of asphalt mixture structure This paper introduces an approach for simulation of aggregate and asphalt mixtures using parameterized shape and size gradation Both the plane geometry

Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates This is done by sieving the aggregates as per IS 2386 (Part I) – 1963 In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves The apparatus used are – i) A set of IS Sieves of

Gradation of Coarse Aggregates Proper gradation of coarse aggregates is one of the most important factors in producing workable concrete Proper gradation ensures that a sample of aggregates contains all standard fractions of aggregate in required proportion such that the sample contains minimum voids Aggregate Gradation Table | Salmon Bay

Gradation Recycled concrete material should be crushed and screened to produce aggregate that satisfies the AASHTO M6 (5) and M80 (6) gradation requirements for PCC With appropriate adjustments a plant can produce any desired gradation Crushed fine aggregates (minus 4 75 mm (No 4 sieve)) are generally not used or are blended with natural sand

Perform the coarse aggregate gradation/sieve analysis according to ASTM C136 Enter the original mass of the sample Enter the individual weights retained in grams for each individual sieve and the pan The individual % of grams retained cumulative % retained cumulative % passing will be calculated

All aggregates are somewhat porous and will absorb water as well as asphalt Limestone and lightweight aggregates are more absorptive than aggregates such as gravel The amount of binder applied to the roadway should compensate for absorption into the cover aggregate More absorptive aggregates also tend to have a higher affinity for asphalt
