ASPHALT PAVEMENT LIFE CYCLE. This is a chemical oxidation process that is often referred to as the aging or age-hardening process. This chemical change at the asphalt binder makes the pavement more brittle and subject to wear and cracking. In addition to hardening, the asphalt also begins a process known as raveling.
Asphalt Plant Tour. Drum plants, which make asphalt continuously and can store the asphalt for several days in heated storage silos. You'll find common components in both batch and drum plants including: Cold feed bins — Accurately meter the different aggregates used in the mix to the drying drum.
Life-cycle Cost. Life-cycle costs of hot-mix asphalt pavements are significantly lower than those of Portland cement concrete pavements. The APA has developed life-cycle cost analysis software that uses the principles recommended by the Federal Highway Administration (FHWA) to compare the economics of alternative designs for a given road project.
The work consists of an analysis of the life cycle of 1 km of road pavement and includes all stages of the life cycle: from extraction of virgin materials to end of life. Three types of pavements are compared, among which one produced with virgin materials and traditional technologies in plant, which is used as a reference, and two in which the use of Reclaimed Asphalt Pavement (RAP) and Warm Mix Asphalt …

Benefit For Professional Customers AQUA PATCH is the perfect solution for Maintenance and Repair Organizations (MRO) Repair Crews: AQUA PATCH is a big time saver for repair crews because it eliminates the need for costly trips back to the asphalt plant.AQUA PATCH doesn’t have the time constraints associated with hot-mix or warm-mix asphalt.
Asphalt is produced in an asphalt plant. The process involves heating the aggregate or rock to about 300° and then mixing the hot liquid asphalt cement with the aggregate. Once the products are heated and well mixed, it is hauled by truck to a job site where crews place the mix with the use of an asphalt paver.
