Relationship Between Porosity, Permeability, and Grain …

Relationship between porosity and permeability of very coarse-grained, coarse- and mediumgrained, silty and clayey sandstones. The interstitial water content (irreducible minimum) was determined with an apparatus using principles of capillarity (BEESON,1953, p.21).

Cohesion Intercept of Soils + Typical Values

Introduction. The cohesion intercept is a term used in describing the shear strength soils. Its definition is mainly derived from the Mohr-Coulomb failure criterion and it is used to describe the non-frictional part of the shear resistance which is independent of the normal stress. In the stress plane of Shear stress-effective normal stress ...

 · The porosity (n%) of Taref Sandstone has a significant correlation with mostly its physical and mechanical properties of the studied sandstone. Through matching correlation data among these parameters, it was clearly indicated that both porosity (n%) and dry density (γd) had been considered as the major parameters influencing other physical and mechanical properties of the studied …

Revised Soil Classification System for Coarse-Fine …

The fines threshold is F t h = 10 – 42 % in coarse-fine mixtures while the sand threshold is F t h = 47 – 70 % in gravel-sand mixtures. The threshold fraction F t h decreases when the relative size ratio R d increases, the liquid limit increases, the coarse grains become well graded, and the particle shape becomes rounder.

5 Aggregate Specifications and Requirements

There is a specific requirement for gravel coarse aggregates regarding crushed particles. This requirement applies, however, only when gravel coarse aggregates are used in HMA, compacted aggregates, and asphalt seal coats except asphalt seal coats used on shoulders. Crushed particles are defined as those particles having one or more sharp, angular, fractured faces. Fractured faces that have an area less than 25 percent of the maximum cross sectional area of the particle are not considered crushed. ASTM D 5821 is used to determine the crushed particle content. Crushed gravel …
