Most of the waste materials recycled for production new construction are by-products various manufacturing processes, such as aggregate washing process. Recycling is paramount importance since it could reduce adverse environmental impacts resulting from landfilling. Various studies have attempted to recycle different types and into concrete paving blocks. However, availability literature on blo...

Surface dressings are a sustainable maintenance alternative for pavements with surface distresses, due to the low amount of resources involved. This paper aims analyze viability using twelve different dressing solutions, including three binders (conventional and modified emulsions, soft 160/220 bitumen) covering diluted emulsion, treatment Portland cement concrete (PCC) pavements. Several test ...

To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

Recent research has developed experimentally verified dynamic models for skid-steered wheeled vehicles and used these results to derive a power model for this important class of all-terrain vehicles. As presented in this paper, based on the torque limitations of the vehicle motors, the dynamic model can be used to develop payload and terrain-dependent minimum turn radius constraints and the pow...

A mathematical model of braking a car using differential equations has been compiled. The calculation scheme the plane-parallel motion during is given. When car, three forces are considered in contact each wheel with road: force, slip resistance and normal reaction road. diagram components force acting plane road when sliding. drawn up to determine reactions on wheels car. To assess preservatio...

To overcome the limitations of pavement skid resistance prediction using friction coefficient, a genetic-algorithm-improved neural network (GAI-NN) was developed in this study. First, three-dimensional (3D) point-cloud data an asphalt surface were obtained smart sensor (Gocator 3110). The coefficient then pendulum tester. 3D dataset analyzed to recover missing and perform denoising. In particul...

The application of asphalt hot mix recycling is one challenge in sustainable road pavement research. In addition to the vast amount research on performance recycled asphalt–concrete, frictional resistance still limited. effects aged and aggregates skid were investigated this carefully extracted from field-reclaimed pavement, engineering mechanical properties virgin measured. degradation was sim...

In mechanized timber harvesting, it is common practice to build brush mats from logging residues on skid trails. Protective effects of brush mats against soil compaction are documented by several studies. On the other hand, a large quantity of nutrients is concentrated on the skid trail. Fully mechanized harvesting has been criticized frequently for this reallocation of nutrients. Is there real...
