Computer-Integrated Methodologies for Real-Time Control of Asphalt Paving Operations

A real-time control system is needed for measuring and improving productivity and quality in asphalt pavement operations. This paper presents four computer integrated methodologies necessary to develop a real-time control system for asphalt paving operation. These methodologies include: (I) simulation modeling for optimal allocation of resources. (2) automatic truck dispatching system to maximize truck productivity. (3) Global Positioning System (GPS) for real-time positional data acquisition. and (4) semi-automated path-planning and real-time guidance system for rolling operations. Interrelating these independent methodologies using a systems approach will allow for the development of a real-time control system for asphalt paving operations. Developing a real-time control system by standardizing construction practices will create a system that is amenable to strict quality and cost control.
