More than 90% of Malaysian roads are constructed using asphaltic concrete. However, previous investigations of asphaltic concrete have mainly concentrated on the macroscopic properties of the composite materials based on the assumption that the mixtures are homogeneous and isotropic. This paper applies a digital image processing technique to compare the orientations of coarse aggregate particle...

soil characteristics is very important in water erosion processes. the present investigation was conducted in gully lands of ardebil province, iran, to assess the role of soil texture and structure on aggregate stability using wet sieve method. to achieve the study purposes, mean weighted diameter of aggregates was calculated, and its relationships with lime and clay percentages, sodium absorpt...

The sources of aggregate productivity growth are explored using detailed data for four-digit U.S. manufacturing industries during 1958-96 and a decomposition formula which allows to quantify the contribution of structural change. Labor productivity as well as total factor productivity are considered and the aggregation is performed with either value-added or employment shares. It is shown that ...

An aggregate game is a normal-form game with the property that each player’s payoff is a function only of his own strategy and an aggregate function of the strategy profile of all players. Aggregate games possess a set of purely algebraic properties that can often provide simple characterizations of equilibrium aggregates without first requiring that one solves for the equilibrium strategy prof...

The Aggregate Demand – Aggregate Supply framework has dominated intermediate macroeconomics textbooks since the 1980s. However, there have been 2007). In spite of these criticisms, the ADAS framework had continued to dominate the textbooks, with little or no response to these criticisms. This paper reviews the main criticisms of the ADAS framework, and then focuses on Gregory Mankiw's presentat...

the purpose of this research was to evaluate the application of recycled aggregates of constructiondebris such as concrete, cement block and rubbles from pars-kangan site in asphalt concrete mix design. toevaluate the performance of aggregates different mix designs with recycled aggregate percentages of 0, 10,30, 50 and bitumen percentages of 4, 4.5, 5, 5.5, 6, and 6.5 were provided and two mar...
