Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading. A particularly interesting question is whether a...

Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces. The design of the structural overlay thickness for rubblized projects is difficult as the resulting structure is neither a true rigid pavement nor a true flexible pavement. The most important aspect of the desig...

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

This paper proposes the use of neural network(NN-) based pavement structural analysis tools as surrogates for the flexible pavement response analysis in the new mechanistic empirical pavement design guide (MEPDG) developed for the American State Highway and Transportation Officials (AASHTO). Some of the recent successful applications of NN-based structural analysis models for predicting critica...

Pavements are vulnerable to subgrade layer performance because it acts as a foundation. Due to significant increase in truck traffic, pavement engineers are challenged to build more strong and long-lasting pavements. To increase the load-bearing capacity of pavements, subgrade layer is often stabilized with cementitious additives. Thus, an overall characterization of cementitiously stabilized s...

paper studies the impact of the liquidity, underpricing and ownership up on both the short term and long term performance of the initial public offer (ipo) stocks in the equity markets of india. empirical analysis is undertaken to study the impact of liquidity, underpricing and ownership on performance of ipo stocks. multiple regression analysis is undertaken for analyzing the impact. it is fou...

are collaborating to evaluate the performances of three flexible pavement designs, including two perpetual/long-life (with and without the rich bottom mix (RBM) layer) and one conventional pavement designs. The three flexible pavement designs are being monitored by strain, pressure, temperature and moisture sensors, which are installed in the asphalt, granular and sub-base layers. Two types of ...

In order to improve the accuracy and reliability of an existing rutting performance prediction model, based on long-term observation data RIOHTrack’s full-scale pavement structure, model in China’s Specifications for Design Highway Asphalt Pavement was evaluated, correction method proposed, which improves model’s makes it more suitable estimation region. The research found that has significant ...
