A soil engineering classification derived from the cone penetration test (CPT) involves uncertainty of correlation between composition and mechanical behavior. This results in overlaps different types currently used CPT systems. Accordingly, two statistical criteria, region estimation point estimation, are suggested to address this problem. Further, a new fuzzy subset approach is introduced develop truly independent classification, establish transition conventional classifications by...
To facilitate the use of recycled materials in pavement construction, a mechanistic-based approach is required to better characterize base materials. This paper demonstrates application shakedown theory behavior traditional and based on laboratory repeated load triaxial (RLT) tests full-scaled accelerated loading tests. A new that dissipated energy proposed explain different responses tested under loading. The illustrated there are two during RLT tests, namely, stable unstable responses,...
Three testing methods for predicting the durability of cement-stabilized soils—the tube suction (TS), 7-day unconfined compression strength (UCS), and wetting–drying tests—were tested compared their correlations influence factors using a problematic low plastic silt clay from subgrade commonly encountered in Louisiana. A series samples was molded at six different cement dosages (2.5, 4.5, 6.5, 8.5, 10.5, 12.5% by dry weight soil) four molding moisture contents (15.5, 18.5, 21.5, 24.5%). The...
The placement of an asphalt overlay on top existing pavement is rarely a lasting solution. Due to continuous movement the pavement, discontinuities such as cracks and joints propagate through causing reflection cracking. Reflection cracking serious challenge associated with rehabilitation. Practical experience shows that propagates at rate 1 in. per year. As need grows for new rehabilitation methodologies improve performance overlays against cracking, number state transportation agencies...
In September of 2005, Hurricane Katrina devastated New Orleans and caused sustained flooding. Limited pre- postflooding tests indicated that the pavement structures tested were adversely impacted by flood water. Consequently, Louisiana Dept. Transportation Development hired an independent contractor to structurally test approximately 383 km (238mi) region's federally aided urban highway system both inside outside flooding area. Falling weight deflectometer (FWD) performed every 161 m (0.1mi)...
Non-structural parameters such as surface distresses and ride quality have commonly been used functional indicators in the treatment selection process. However, transportation agencies considered recent years implementing structural capacity into their pavement management system (PMS) decision-making processes. The objective of this study was to develop a condition index for Louisiana, known Structural Health Index (SHI), on scale from 0 100 that describes integrity structure based...
When adjacent foundation pits are excavated concurrently, the stress and deformation of soil structures affected by their interactions. This paper investigates performance two deep in Shanghai soft clay. These were concurrently with respective excavation depths 15.45 18.50 m 20-mm-wide confined middle zone (middle pits). The behavior wall deflections was examined on basis measured data. Results indicated that (1) greater lateral deflection rates observed for walls side (distant from pits)...
The Rolling Wheel Deflectometer (RWD) offers the benefit to measure pavement deflection without causing any traffic interruption or compromising safety along tested road segments. This paper presents a detailed field evaluation of RWD system in Louisiana, which 16 sites representing wide array conditions were tested. Measurements used assess repeatability measurements, effect truck speeds, and relationship between (FWD) measurements conditions. On basis results experimental program, it was...
To improve engine power at high altitude, the regulated two-stage turbocharger (RTST) which was applied to different altitudes developed by authors. The working process model of heavy-duty common-rail diesel matched with RTST built study regulating characteristic variable geometry (VGT) vane and both turbine bypass valves also matching performance altitudes. control scheme operating conditions first put forward, optimal opening maps VGT were obtained. results show that openings decrease...
Nonstructural factors, such as surface distresses and ride quality, have been commonly used the main indicators of in-service pavement conditions. In last decade, concept implementing a structural condition index in management system (PMS) to complement functional indices has become an important goal for many highway agencies. The rolling wheel deflectometer (RWD) provides ability measure deflection while operating at posted speed limits causing no user delays. objective this study was...
Although the use of a controlled atmosphere is one most successful storage techniques, mechanism thereof in rice remains unclear. We stored aromatic cultivar Daohuaxiang package filled with 98 % N2 and 35 CO2 for 3 months. investigated 2-acetyl-1-pyrroline loss, enzyme activities, proteomics changes during storage. The results showed that content was reduced by 37.40 %, 25.65 43.89 using N2, storage, conventional Controlled slowed down increase malondialdehyde Daohuaxiang. 26S proteasome...
