Reflective cracking is one of the primary forms deterioration in pavements. It widespread when Asphalt concrete (AC) overlays are built over a rigid pavement with discontinuities on its surface. Thus, this research work aims to reduce reflection cracks asphalt overlay pavement. Concrete slab specimens were prepared three thicknesses (4, 5, and 6 cm). All these by testing machine designed manufa...

Language: English The Challenge At the outset the asphalt paving process seems to be simple. Trucks deliver hot mix asphalt from plants to the construction site. There the asphalt is loaded on asphalt pavers that evenly spread the asphalt. Finally, compactors compact the asphalt to its required density. Despite this relatively structured process our research shows that there are significant dis...

Rutting of asphalt pavement occurs earlier and is more serious under the increasingly heavy traffic load conditions that can be found in subtropical monsoon climate regions. High modulus concrete (HMAC) with excellent anti-rutting anti-fatigue properties generally used to mitigate this issue. Given relatively high cost additives type asphalt, study feasibility using recycled mixture (RAP) Trini...

Abstract Asphalt mixture is a combination of aggregate and asphalt. Sinabung eruption volcanic ash produced many negative impact on health the environment. So that needs to be done in order study can used road pavement, especially Concrete purpose this determine effect comparison filler sinabung - Binder Course. This research was laboratory experimental nature with asphalt level variation 5%, 5...

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...

BACKGROUND Asphalt workers are exposed to bitumen fume and vapour, and to exhaust from engines and passing traffic. AIMS To assess the occurrence of respiratory symptoms and signs of airflow limitations in a group of asphalt workers. METHODS All 64 asphalt workers and a reference group of 195 outdoor construction workers from the same company participated in a cross-sectional study. Spirome...
