Asphalt mixture cracking has become the dominant type of asphalt pavement distress in Indiana. In recent years, efforts have shifted away from standard Superpave design method search methods to improve resistance pavements cracking-related distress. This paper presents a review applicability Illinois Flexibility Index Test (I-FIT) evaluate potential Indiana mixtures. this study, two indices were compared: flexibility index (FI) and (CRI), both derived load-displacement curve. The quality...
This paper presents an evaluation of the rutting performance geosynthetics in asphalt pavements. The both a fibreglass geogrid and sheet reinforcement material were evaluated using third-scale model mobile loading simulator (MMLS3). surface profile each type reinforced slab (and control slab) was monitored compared. To investigate movement mixtures caused by MMLS3 as well interfaces reinforcements slabs, trench cuts made once tests complete. results demonstrated that can reduce downward ruts...
Intelligent compaction (IC) is an emerging technology that can be applied to improve the of hot mix asphalt (HMA). This study investigated applicability IC for quality control (QC) and/or assurance (QA) HMA through a survey, phone interviews, and review demonstrations conducted in Indiana. The questionnaire survey gathered information about (1) field usage by state DOTs, (2) benefits technology, (3) future plans implementation. Only two DOTs have adopted QC, whereas other 24 respondents not...
This paper presents a new method for the local calibration of rutting models in Mechanistic–Empirical Pavement Design Guide (MEPDG) Indiana’s pavements using accelerated pavement testing (APT). The study focused on verification, calibration, and validation MEPDG both field APT sections. In this study, methodology was developed that uses layer distribution. Also, procedure to provide most realistic simulations conditions (climate, traffic, aging) virtual weather station data generation,...
This paper describes a neural network model for an electrical differential system electric vehicle. When vehicle drives along curved road lane, the speed of inner wheel has to be different from that outer in order prevent vibrating and traveling unsteady path. Because each this independent driving force, is required replace gear system. However, it difficult analysis nonlinear behavior relation steering angle, as well structure. Therefore, used learn relationships. To realize model, data was...
After the implementation of Mechanistic-Empirical Pavement Design Guide (MEPDG) in Indiana, an overall evaluation stiffness characteristics local AC mixtures and ability level III MEPDG predictive equations to estimate dynamic modulus (E*) with was required. Therefore, primary objectives this study were identify significant differences among Indiana asphalt mixtures, evaluate performance commonly used E* models, assess influence input on pavement design life typical structures. It found that...
This paper investigates the applicability of Hamburg wheel-tracking test (HWTT) for asphalt mixture quality acceptance using laboratory-compacted specimens and field-compacted specimens. Density distribution functions rut depths, stripping inflection points, rutting resistance index (RRI) values used in HWTT were obtained mixtures with different nominal maximum aggregate size (NMAS) binder performance grades. Clear distinctions among depth distributions high-temperature grade observed The...
Abstract This paper presents a development in measuring skid resistance laboratory performance test for chip seal. It is important to develop relationship between the British pendulum (BPT) and locked-wheel (LWST), or grip tester (GT). The seal typical pavement preservation treatment used by North Carolina Dept. of Transportation (NCDOT). In America, loss common road condition that indicates need seal, as one major advantages an increase resistance. Most agencies have specified cycle which...
Abstract This study presents quantifications of the electrical interactions between aggregates and emulsions using zeta potentials evaluates interaction influence on seal coat curing aggregate loss performances. Three seven consisting CRS-2P, RS-2P, AE-90S for Trap Rock, Sandstone, Blast Furnace Slag, Steel Limestone, Dolomite, Crushed Gravel were used potential electrostatic interaction, water content test performance, sweep performance. All showed positive at a low pH negative high with...
This paper presents a new test protocol for the performance evaluation of bituminous surface treatments (BSTs) using third-scale Model Mobile Loading Simulator (MMLS3). The BST characteristics covered by this include aggregate retention, bleeding, skid resistance, embedment depth, cracking, and rutting. In study, MMLS3 method was applied to evaluate effects various mix parameters on retention bleeding; these emulsion application rates, fines content, gradation. Results demonstrate that...
Abstract This paper presents an evaluation of maltene rejuvenator effectiveness. The was applied on the U.S.-40 highway in Henry County, IN, and its performance monitored evaluated using four different methods: (1) friction, (2) permeability test, (3) dynamic shear rheometer, (4) contact-angle test. results demonstrate that has no significant effects pavement permeability. However, reduced moduli (i.e., modulus, viscous elastic modulus), increased phase angle, water drop contact angle...
This paper reports on the controlled synthesis of 3D CuO nanogrids by combined use electrospinning and thermal oxidation a composite metal mesh/polymer mat architecture. The obtained result from three steps encompassing: (i) Cu atom clusters diffusing into nanofibers producing polymer-metal “core-shell”-type fibers (ii) decomposition polymeric shell; (iii) metallic core to form self-supported, open consisting continuous nanoparticles with an average diameter 20 nm. calculated band gap energy...
We report the growth of high-quality GaN epitaxial thin films on graphene-coated c-sapphire substrates using pulsed-mode metalorganic vapor-phase epitaxy, together with fabrication freestanding by simple mechanical exfoliation for transferable light-emitting diodes (LEDs). High-quality grown sapphire were easily lifted off thermal release tape and transferred onto foreign substrates. Furthermore, we revealed that pulsed operation ammonia flow during was a critical factor films. These films,...
The primary goal of pathway analysis using transcriptome data is to find significantly perturbed pathways. However, not always successful in identifying pathways that are truly relevant the context under study. A major reason for this difficulty a single gene involved multiple In KEGG database, there 146 genes, each which more than 20 Thus activation even will result many This complex relationship often makes very difficult. While we need much powerful methods, readily available alternative...
