Abstract Weak lateritic subgrades are more often than not encountered during road construction in Ghana. This makes it necessary to find economically efficient ways improve the engineering properties of these marginal soils. The objective this study is investigate effects coconut fiber (30 mm, 60 mm and 90 lengths) palm on some geotechnical characteristics a weak subgrade. soil was collected fr...
From the perspective of sustainable waste management and its environmental impact, biomass bottom ash (BA) remains problematic challenging to use as a recycling material for civil engineering infrastructures. This study evaluated performance lateritic soil (LS), stabilized with cement BA, subbase material. BA has been considered replacement in LS prior introduction hydraulic stabilization means...
Expansive soil needs to undergo treatment be used as safe foundation for roads and buildings. From an environmental conservation economical point of view, the usage agricultural industrial wastes is best option. In this study, effects utilizing plastic waste marble dust on engineering properties expansive soils were examined. Various laboratory tests carried out sampled by adding 10, 15, 20% 0....
Abstract Road construction over soft subgrade soil is a major issue affecting cost and scheduling of highway projects. Many techniques have been conducted to strengthen the subgrade. One them are using additives such as coconut shells, rice husk ash, stone dust, fly ash. soil. The strength commonly expressed California Bearing Ratio (CBR). In this study, crushed shells (CCS) 65 mm 10 ranges siz...
seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. this devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.the base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...
This paper analyzes and compares the responses of a two-storied steel structure to 1994 Northridge earthquake in California. Response modal nonlinear time-history dynamic analysis was especially used on with fixed-base base-isolated systems show realistic behavior structure. Intuitively, best choice for seismic isolation technique is use flexible element, or an isolator, at structure’s base, wh...
1 State Supervisor of Prosthetic Services, Ministry of Social Affairs, Helsinki, Finland. The original patellar-tendon-bearing (PTB) prosthesis was constructed at the Biomechanics Laboratory of the University of California. For details regarding the anatomical and physiological considerations (J), the biomechanics (4), and the construction (2), the reader is referred to the June 1962 issue of A...
INTRODUCTION The objective of this study was to examine reimbursement trends for emergency provider professional services following the balance billing ban in California. METHODS We conducted a blinded web-based survey to collect claims data from emergency providers and billing companies. Members of the California Chapter of the American College of Emergency Physicians (California ACEP) reimb...
In the recent times, use of geosynthetic-reinforced soil (GRS) technology has become popular for constructing safe and sustainable pavement structures. The strength subgrade is routinely assessed in terms its California bearing ratio (CBR). However, past, no effort was made to develop a method evaluating CBR reinforced soil. main aim this paper explore appraise competency several intelligent mo...
The strength comparison of fibre reinforced peat and clayey-silt for the compacted sub-grade by using reinforcement technique from scrap tire is presented. tires are extracted shredded into a standard size, i.e., rubber-chip, rubber-crumb, rubber-powder fibre-polyester consistency homogeneity design mix. In this study, two types fibres used, which polyester rubber crumb. at various designated p...
