Each year, more than 25 percent of highway fatalities in the United States occur at or near horizontal curves, according to the Federal Highway Administration (FHWA). In an attempt to save lives and prevent injuries, some 30 states across the U.S. are applying high friction surfaces (HFS) to improve skid resistance at locations with a high incident of vehicle crashes such as severe horizontal c...

The application of recycled asphalt pavement (RAP) on a large scale is highly promoted to meet the current needs carbon neutrality and sustainable development purposes. However, majority RAP mixture productions are currently relying restoring effects provided by rejuvenators. Therefore, study focuses feasibility using high penetration binder (HPAB) in as replacement for conventional In this stu...

In this study, an artificial neural network was developed in order to analyze flexible pavement structure and determine its critical responses under the influence of standard axle loading. In doing so, more than 10000 four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, and subgrade soil were analyzed under the impact of standard axle loading. P...

Traditionally, fatigue cracking in asphalt pavement means failure, which is the basis for controlling design thickness of pavements. In fact, failure pavements includes three stages: cracking, crack expansion, and structural failure. Therefore, this paper aims to investigate life bottom-up concrete (AC) considering different stages The dynamic modulus AC grades was experimentally determined. te...

ABSTRAKPenggunaan lapis tambah pada perkerasan jalan adalah upaya untuk memperbaiki kondisi fungsional dan struktural, karena memiliki masa pakai yang terbatas. Seiring bertambahnya usia, akan semakin buruk hingga memerlukan rehabilitasi. Penelitian ini bertujuan mengembangkan perangkat lunak tebal bernama "OVRL" dengan mengikuti pedoman Pd T-05-2005-B menggunakan metode lendutan melibatkan ala...

The regulation of Rho of plants (ROP) in morphogenesis of leaf epidermal cells has been well studied, but the roles concerning regulators of ROPs such as RhoGDIs are poorly understood. This study reports that AtRhoGDI1 (GDI1) acts as a versatile regulator to modulate development of seedlings and leaf pavement cells. In mutant gdi1, leaf pavement cells showed shorter lobes in comparison with tho...

To investigate the involvement of the yolk-sac membrane in ion absorption, developmental changes in whole-body cation contents, cellular localization of vacuolar-type H(+)-ATPase (V-ATPase), and size and density of pavement and chloride cells in the yolk-sac membrane were examined in tilapia (Oreochromis mossambicus) larvae in fresh water (FW) and those transferred to seawater (SW) at 2 days be...

In pavement management, prioritized resource allocation is imperative given the fact that there is rarely enough funding with highway agencies to address all the pavement sections. In view of the complexity involved in the decision making process, subjective evaluation based on expert’s judgments is unavoidable. Analytic Hierarchy process (AHP) has been applied by researchers to solve pavement ...

Longitudinally tined (LT) concrete pavement surfaces were shown to produce less noise than transversely tined (TT) ones, making them more desirable where traffic noise may be an issue, if the two textures are shown to have equivalent safety performance. The present effort focused on rural freeway crashes between 1991 and 1998. This guaranteed the presence of high speeds and absence of various f...

Highway pavement are deteriorating fast due to lack of timely maintenance, leading to higher vehicle operating costs, increasing number of accidents etc. Thus, timely maintenance of the highway pavement is essential. Because, once pavements start to deteriorate; they deteriorate rapidly beyond the point where maintenance is effective. Thus, there is an urgent need to develop a strategy for main...
