Oil pollution causes deterioration of the physical, chemical, mechanical, and geotechnical characteristics affected soil leading to loss productivity for engineering purposes. Different stabilization methods serve as a remedy such regain its properties. This study was concerned with utilization lime stabilize crude oil contaminated investigate efficacy stabilization. The also focused on determi...

This study resulted from the need for better consideration of subgrade and unbound layers on performance flexible pavements in Kansas. Thus, main objective was to develop pavement prediction models with emphasis effects layers. To this end, distress data, which were collected over several years across state Kansas, including rutting, fatigue cracking, transverse roughness core analysis, served ...

Abstract The objective of this study was to evaluate the suitability steel slag as an additive engineering properties weak clay soil. Different geotechnical laboratory tests were conducted on both stabilized and natural soils. Steel (SS) added at a rate 0, 5, 10, 15, 20, 25% Specific gravity, grain size analysis, Atterberg limit test, compaction free swell, California bearing ratio (CBR), uncon...

Newly, the utilization of polypropene for packaging consumer products was populated significantly, which might make ecological problems. So, it is substantial to detect environmentally friendly techniques recycle these waste substances without causing any environmental risks. One such technique could be utilize poly wastes as stabilizer agents soils. In current investigation, textiled-poly bags...

OBJECTIVE To assess the geographic distribution and trends of AIDS deaths for the 1988-1997 period in Mexico. MATERIAL AND METHODS Crude and adjusted mortality rates were estimated for the 1988-1997 period. A trend test was performed using the simple linear regression method. Standardized mortality ratios (SMR) and years of potential life lost (YPLL) were calculated for each Mexican state. ...

New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festu...
