In the design of road construction site engineers faces the problem of low strength of soil, due to which settlement and failure of road pavement occurs. For improving the strength of soil pavement Hypo Sludge and Lime can be utilized to the soil. In present studies a series of laboratory experiment performed to determine optimum percentage of these two additives. 6% Hypo Sludge or 8% Lime is

In this paper, asphalt pavement design criteria will be displayed and a considerable review on the use of crumb rubber in asphalt pavement reinforcement will be presented and discussed. It also includes a review on the effects of CRM on the stiffness, rutting, and fatigue resistance of road pavement. In order to understand the asphaltrubber reinforcement technology, asphalt properties and
Wastewater treatment plant (WWTP) residuals (paper sludge), boiler ash, and causticizing residues are among the byproducts associated with pulp and paper production that can also be recycled into different applications. WWTP residuals are composed of the solids removed from process water. They consist mostly of wood fibers and mineral matter such as kaolin clay and calcium carbonate. Boiler

Rapid Determination of Wastewater Sludge Dewatering . The handling of wastewater sludge is a significant challenge, because the amount of wastewater sludge is large, the handling, processing and final disposal of sludge are difficult and expensive, which could count for 40% of total operational costs of a wastewater treatment facility.

Paper fibers have a degradation point of 300–500 °C, therefore, they cannot be dissolved during asphalt production (150 °C200 °C). Research results on using paper fiber as asphalt additives are relatively limited. Wang found that lignin fibers (has similar properties with paper fiber) provided enhanced strength, improved abrasion resistance, and superior moisture susceptibility

sludge concretes a section of road pavement is designed. Cost of sections is estimated. The economic analysis shows that replacement up to certain proportion makes the overall design economical. This provides an environmental friendly method of hypo sludge disposal. KEYWORDS: Hypo Sludge, Rigid Pavement, Flexural Strength, Techno, Economic INTRODUCTION Hypo sludge consumes a large
The use of paper industry sludge in stone mastic asphalt as a fiber additive has also been studied. Four different sludges were examined, and the deinking sludge was found to be the most suitable. However, all four tested sludges passed the general specifications for medium and heavytraffic road pavement, according to the Department of Public Works and Highways . In addition, other
