The reduction in the ability of bitumen to bond with aggregate surface due infiltration moisture has been recognised for years, and this deterioration phenomenon is called damage. In general, loss bonding between shortens service life top layer pavement. Many investigations have conducted understand mechanisms damage strength find ways improve strengthen mitigate effect moisture. This paper reviews extensive literature on bitumen-aggregate asphalt mixtures. general description theories that...
Airport pavements deteriorate with age due to the impacts of environmental factors and air traffic. There is a dearth studies on scheduling airport pavement maintenance importance assessing different strategies using Life-Cycle Cost Analysis (LCCA). An analysis cost–benefit study delay in alternatives should be done determine whether one-year beneficial. This concerns management systems significance several preservation depending inputs outputs based data from Rocky Mountain Metropolitan...
Machine learning (ML) models are excellent alternative solutions to model complex engineering issues with high reliability and accuracy. This paper presents two extensively explored ensemble for predicting asphalt pavement temperature, the Markov chain Monte Carlo (MCMC) random forest (RF). The RF multiple MCMC (RF-MCMC) were used hybridise proposed algorithms optimal prediction of temperature. study thermal instruments measure temperature in Gaza Strip, Palestine. measurements made at a...
Researchers are exploring the utilisation of reclaimed asphalt pavement (RAP) as a recycled material to determine performance non-renewable natural aggregates and other road products such binder, in construction rehabilitation stage pavements. The addition RAP mixtures is complex process there need understand design mixture. Some problems associated with adding moisture damage cracking caused by poor adhesion between binder. There add rejuvenators mixture containing enhance its performance,...
This study was conducted to investigate the effect of ageing on bitumen, before and after modification. Nano-clay modified bitumen (NCMB) produced by adding nano-clay (NC) 60/70 penetration grade bitumen; then, binder tested using conventional tests for properties such as penetration, softening point viscosity. These were carried out ageing. A rolling thin film oven (RTFO) used simulate short-term (STA), a pressure vessel (PAV) long-term (LTA) binder. After initial results showed an...
Airports play a critical role in transporting goods and passengers supporting the growth of world economy. spend huge sums annually to maintain improve pavement functions by expanding runways, taxiways, aprons, perform routine maintenance rehabilitation existing pavements. Besides traditional direct costs, comprehensive airport management system should also consider indirect costs such as fuel, crew, passenger delay, aircraft maintenance, loss revenue when conducting life-cycle cost analysis...
Road safety and pavement condition are considered top priorities in our civilized societies, it’s important that the remains an excellent state for a long time. However, eventually, will get exposed to different types of distresses as result traffic loads, rough environment conditions, soil underline subgrade. Therefore, achieve required standards surface roads country provide best performance: detection measurements extension must be included maintenance preparation. This paper proposes...
Bonding strength of bitumen is one the most important properties in need independent evaluation. Conducting a pull-off test to determine bonding can be done using Universal Test Machine (UTM). In this work, UTM was used investigate effect adding an additive with 60/70 penetration grade bitumen; nano-clay at percentage 2% and 4%. A designed mold fabricated granite stainless steel substrates. The investigation covered influence variation mixing process (mixing duration power rotation during...
This study investigates the effects of ageing simulation on physical properties nano-clay modified bitumens (NCMBs). Bitumen with penetration grade 60/70 is 0, 2 and 4% nano-clay, consistency samples characterized using penetration, softening point, viscosity tests before after aging. Atomic force microscopy (AFM) used to evaluate surface roughness tip deflection bitumens. The results revealed that incorporation up NC resulted in increased hardness bitumen, all were affected by ageing; for...
This study uses the artificial neural network and response surface methodology to develop two models for predicting rheological properties, complex modulus (G*) phase angle (δ) of bitumen-filler mastic. It also analyses evaluates accuracy both by determining coefficient determination (R2), mean squared error (MSE), root (RMSE). The prediction use G* δ data from a previous researchers at Nottingham Transportation Engineering Centre determine three types mastic (limestone, cement grit stone)...
