Cold in place recycling, as an alternative to milling and standard replacement, shows a series of technical, economic and environmental advantages, which have done its use to grow in Spain, especially from 1990 onwards. Nevertheless, these actions have revealed certain aspects and limitations that prevent cold recycling from being considered a fully consolidated technique nowadays. The use of v...

In this report, we conducted a questionnaire survey targeting contractors who perform placing and compaction of concrete, investigated the actual conditions compaction. As result, description in JASS 5 is standard for ordinary so number workers, rod diameter internal vibrators, etc. been determined according to construction conditions. addition, there were many opinions that it was expected pos...

Quantitative analysis of depth-converted reflection times defines long-term differential motion across individual structures in a central Appalachian interior basin known as the Rome trough. Differential motion decreases exponentially with time. Rotation about a hinge defining the trough’s west margin reached approximately 37% of total displacement in about 63–78 million years (m.y.). Displacem...

Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

Compaction of porous rocks can occur in two modes: uniform and localized. Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly...

Earth bricks are a traditional eco-friendly construction material. In this study, harbor-dredged sediments were used along with hemp shiv to develop brick manufacturing procedure and compaction techniques produce durable earth for the valorization of waste dredged sediments. Prismatic specimens size 4 × 16 cm3 manufactured Dunkirk after analyzing their suitability according French standard flex...

Background Interest in left ventricular non-compaction (LVNC) as a distinct clinical form of cardiomyopathy is supported by recent publications. Echocardiographic and select cardiac MRI criteria have been established which are used to facilitate the diagnosis and have led to concerns of diagnostic accuracy. We used cardiac magnetic resonance imaging (cMRI) to assess standard criteria for LVNC.

Soil compaction can affect crop growth and greenhouse gas emission and information is required of how both these aspects are affected by compaction intensity and weather. In this paper we describe treatments of compaction intensity and their effects on soil physical conditions and crop growth in loam to sandy loam cambisol soils. Soil conditions and crop performance were measured over three sea...
