Book Description
The Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center has been developing robotic equipment and machinery for highway maintenance and construction operations. It is a cooperative venture between the University of California at Davis and the California Department of Transportation (Caltrans). The research and development projects have the goal of increasing safety and efficiency of roadwork operations through the appropriate application of automation solutions. This report describes the continuing development of automated equipment for deploying and retrieving traffic cones. In this latest phase of the project, the center has continued the development of the automated cone machine (ACM) through further testing and development of the first generation integrated prototype ACM and the design and fabrication of an integrated Multi-stack ACM developed to maximize the number of cones carried by the automated cone machine. Included in this report is the development of an improved control system for the retrieval arm which is a critical component used to pick up the traffic cone off the road. A first generation ACM prototype (ACM 1) is being used in tests and demonstrations on the highways of California. Operators using ACM 1 can place and retrieve cones without any set up and control the machine from within the confines of the cab. These machines can easily be run by a single operator and are very compatible with the process of closing a lane. The ACM 1 design was integrated into the existing Caltrans manual cone body truck and was limited to two stacks of 40 cones each. The new ACM multistack is designed to carry six stacks of 50 cones for a total of 300 cones. These machines are unambiguous demonstrations of the successful application of automation in a very demanding environment. This development work and the continued support of commercialization at AHMCT support the Caltrans goal of making these machines available to the maintenance operations.

Book Description
Polyvinyl chloride (PVC) has been around since the late part of the 19th century, although it was not produced commercially until the 1920s; it is the second largest consumed plastic material after polyethylene. PVC products can be rigid or flexible, opaque or transparent, coloured, and insulating or conducting. There is not just one PVC but a whole family of products tailor-made to suit the needs of each application. PVC is extremely cost effective in comparison to other plastics with a high degree of versatility in end-use and processing possibilities, as the reader will note from this book. It is durable, easily maintained, and can be produced in a large range of colours. As a result PVC finds use in an extensive range of applications in virtually all areas of human activity, including medical equipment, construction applications such as flexible roof membranes, pipes and window profiles, toys, automotive parts and electrical cabling. The PVC industry has also started to tackle some of its end-of-life issues. This practical guide provides comprehensive background on the resins and additives, their properties and processing characteristics, as well as discussion of product design and development issues. There have been, and still are, issues and perceptions over environmental and health acceptance covering vinyl chloride monomer, dioxins, phthalate plasticisers, and lead (and cadmium) based heat stabilisers and these are discussed in depth in this book. This book will be of interest to raw materials suppliers and processors or end-users of PVC, as well as anyone with a general interest in this versatile material: resins and additives properties and testing design issues processing, including post processing and assembly property enhancement sustainable development
