Book Description
ABSTRACT: This study examines the impacts, positive and negative, that various materials and installation processes have on the environment when applied to pathway and bridge construction. The literature review, covers traditional materials used in for these types of projects. Materials reviewed include concrete, pervious concrete, steel, wood, asphalt, crushed stone, mulch, and brick pavers. Traditional construction techniques are described and evaluated for their low impact performance. Low impact is defined in this study as minimal area surrounding the construction work being impacted by both square footage and weight equipment and material needed to build the pathway. With regard to bridge construction top down construction technique is compared to traditional pedestrian bridge construction techniques. The top down method has less of an environmental impact on the underlying and surrounding area than that of traditional methods. The data in the literature review was obtained through various sources determining the make-up of each material and the cost and materials needed to have it installed. Overall, the study will bring further insight to evaluating construction methods based on a low impact performance matrix.
