Name the aggregate gradation type shown in Figure 1 and explain what the curve slope indicates. Name the common bituminous mixture with this gradation and describe how the gradation features influence the bituminous mixture characteristics

1. Calculate the following properties for the data provided in the Table below for a coarse aggregate sample. a. Bulk SSD specific gravity b. Bulk Dry specific gravity A Bulk Dry Sp. Gr. = c. Apparent specific gravity d. Absorption capacity. В — С B Bulk SSD Sp. Gr. = В — С where A Apparent Sp. Gr. = А — С A = dry weight B = SSD weight C = submerged weight В — А (100) A Absorption (%) Weight of Pan + Oven- Dry Aggregate Weight of Pan Weight of Submerged Aggregate Weight of Pan + SD Aggregate 0.8495 Ib 1.9885 lb 0.6870 lb 1.9630 Ib 2. If the Moisture Content of a stockpile sample of the same coarse aggregates is 1.85 %, what is the moisture state of aggregate sample? Select from the four standard moisture states. Explain how you arrived at the answer. 3. If Bulk unit weight of coarse aggerates is 98 Ib/ft³determine the % Voids of dry-rodded aggregate. Youlk S.G(Bulk Dry)*Pwater %Solids * 100 4. Determine the % solids for 2 cases discussed in pre-lab video by using below data.…

A 1g granular powder have the following data below, compute for the following: Volume of the solid alone = 1 cm3/g Volume of intraparticle pores = 0.2 cm3/2g Volume of spaces between particle = 3.2 cm3/g Volume after tapping = 2.4 cm3/2g Note: Answer should be in three decimal places A) Specific volume = ? cm3/g B) Specific granule volume = ? cm3/g C) Specific bulk volume = ? cm3/g D) Total porosity = ? E) Interspace porosity = ? F) Intraparticle porosity = ? G) Hausner ratio = ? H) Carr's compressibility index = ?
