Another asphaltic concrete mixture consists of 42% coarse aggregates, 51% fine aggregates, and 7% mineral fillers. The respective bulk specific gravities of these materials are 2.600, 2.710, and 2.690. The asphalt cement content of the total weight of the mix of a sample is 5.5%. The bulk specific gravity of the sample was calculated as 2.467, and the maximum bulk specific gravity of the mix was estimated using ASTM D2041 as 2.562. Determine the value of the sample's air voids,...

An aggregate blend is composed of 59% coarse aggregate by weight (Sp Gr. 2635), 36% fine aggregate (Sp. G. 2.710), and 5% filler (Sp. Gr. 2.748). The compacted specimen contains 6% asphalt binder (Sp Gr. 1.088) by weight of total mix, and has a bulk density of 143.9 lb/t Ignoring absorption, compute the percent voids in total mix, percent voids in mineral aggregate, and the percent voids filled with asphalt.

use (absolute volume method). Calculate the materials (type II cement, coarse aggregate, fine aggregate, and water) needed to make 16 concrete cylinders (diameter = 4", height = 8") for our compression tests. Specified compressive strength = 3000 psi at 28 days. For coarse aggregate, please choose 3/4 in max size gravel containing some crushed particles with the following assumptions: oven-dry specific gravity of 2.68; oven-dry rodded unit weight: 100 lb per cu. ft; moisture content: 1%.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
