Abstract. Compaction quality and density of longitudinal joints are critical to the service life of asphalt pavements. Maintaining deteriorated longitudinal joints has become challenging for many highway agencies. A poorly constructed low-density joint can prematurely distress an otherwise sound flexible pavement, leading to its performance issues in the long run. Longitudinal joints are built...
Abstract. Recently, the cost of road repairs increases every year because of an early-age distresses and the fact that the quality of the concrete mixtures produced in a batch plants are not stable. A stable quality control of cement concrete mixtures is very important in construction site. This paper de-scribes the development of quality control equipment and technology using Internet of...
Abstract. Highway concrete pavement infrastructure built in California during the 1960s-1970s required major rehabilitation by the end of the 1990s. Due to increasing traffic and impact on users caused by long-term closures, the California Department of Transportation (Caltrans) was forced to look for novel strategies to repair highway pavement quickly. Following the successful completion of...
Abstract. Cold mix patching materials (CMPMs) have become increasingly popular solutions for the emergency asphalt repairs of small- to medium-sized potholes in severe winter conditions or where short reopening times are required. Their performances need to be carefully monitored in the early post-application phases, when these materials have a high potential to face several distresses. The...
Abstract. Anti-oxidation is one of the important functions of preventive maintenance for asphalt pavements. The major working principle of preven-tive maintenance’s anti-oxidation is to retard the entrance of oxygen into the asphalt pavements. To advance the quantitative evaluation of preven-tive maintenance’s oxidation resistance, this study investigates the feasi-bility of using the oxygen...
Abstract. Narrow trenching on road pavement has become a widespread practice for installing telecommunication infrastructures on road pavements. Although such technique guarantees a social and environmentally sustainable construction, the quality of the backfilling plays a crucial role in both the short- and long-term properties of the trench. In this context, the present research aims to...
