Abstract - Aggregate as the main constituent of concrete about 70.0% to 80.0 % occupy the total volume of the concrete. They highly affect the both fresh and hardened concrete properties of the concrete. By using the optimization techniques such as Talbot's grading curve or Power curve, Coarseness factor chart and Fineness modulus.

Fuzzy modelling is a type of computerized reasoning used to simulate the real plant operation. In this work, a lot of agent degree information for …
The fine aggregate curves as seen from Fig. 6(b) showed well graded curves using IS and particle packing methods and CPM method showed nearer values to the IS gradation curve. Similarly, the gradation curves of coarse and fine aggregate developed using MTM, JDD and CPM and ASTM C33-18 proportions are shown in Fig. 7.
— The part of aggregate processing investigated in this paper is the crushing, specifically primary crushing using a jaw crusher. Coarse aggregates for unbound use are often produced using a single crushing stage in a jaw crusher, as opposed to concrete or asphalt aggregates, where at least two and often three or four crushing stages are used ...

The white grading curves of the used source materials are displayed in Figure 4 and the binder content along with the RAP aggregate density are summarised in Table 2. These results show that the two slab/milled RAP blends (source 2 and 3) are very similar in terms of gradation, aggregate density, toughness, and binder content.
