An asphalt concrete specimen was blended together from 5 % asphalt binder (by weight) and aggregates with a specific gravity of 2.830. The bulk specific gravity of the asphalt concrete mixture was measured with 2.660 and the theoretical maximum specific gravity was determined at 2.795. Ignore absorption for all following calculations. a) the voids in the total mixture b) voids in the mineral aggregate

A bituminous mixture contains 65% coarse aggregate, 35% fine aggregate (by weight of total aggregate) and 4.8% asphalt (by weight of the mixture). Determine the bulk specific gravity of the mixture if, after compaction, it contains 7.0% air voids. Assume that the aggregate absorbs 0.3% of the asphalt by weight of the aggregate. The specific gravities of the materials are: Coarse Aggregate 2.723 Fine Aggregate 2.664 - 1.05

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,...

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...
