- Given the specifications for an asphaltic concrete mixture and the results of a sieve analysis, determine the proportion of different aggregates to obtain the required gradation. Coarse aggregates: 60% Fine aggregates: 35% Filler: 5%Define the following terms:a. Saturated surface-dry condition of aggregatesb. Absorption of aggregatesc. Free water on aggregatesd. Referring to Figure , which portion of the water in the aggregate reacts with the cement in the PCC mix?8. What is the maximum allowable limit of Materials Finer Than 75 Mm (No. 200) Sieve in Coarse Aggregates in % according ASTM C33? 9. What is the maximum allowable limit (in %) of clay lumps and friable particles in fine and coarse aggregates? 10.

- The mass of aggregate B has been reduced and weighed to conduct an aggregate test shown in Table 2. (e) Calculate the: (iii)apparent specific gravity, and the (iv) aggregate absorption.A sample of lightweight coarse aggregate weighs 532.3 g when oven-dried, 615.7 g when saturated surface-dried, and 191.3 g when submerged. Calculate the bulk specific gravity, apparent specific gravity, and percent absorption.TEST PROCEDURE: 1. Dry the aggregate test sample to a constant weight at a temperature of 110 ± 5°C, then cool to room temperature. 2. Select suitable sieve sizes to furnish the information required by the specifications covering the material to be tested. Common sieves in millimeters are 37.5, 25, 19, 12.5, 9.5, 4.75, 2.36, 1.18, 0.6, 0.3, 0.15, and 0.075 mm (11 2 in., 1 in., 3 4 in., 1 2 in., 3 8 in., No. 4, No. 8, No. 16, No. 30, No. 50, No. 100, and No. 200). 3. Nest the sieves in order of decreasing size of opening, and place the aggregate sample on the top sieve. 4. Agitate the sieves by hand or by mechanical apparatus for a sufficient period. The criterion for sieving time is that, after completion, not more than 1% of the residue on any individual sieve will pass that sieve during 1 minute of continuous hand sieving. 5. Determine the weight of each size increment. 6. The total weight of the material after sieving should be compared with the original weight of the sample placed…
