S.W.COLE provided geotechnical engineering and construction materials testing services associated with proposed improvements to the stormwater collection and drainage systems at a Madbury, New Hampshire metal recycling facility. The facility used for metal recycling consists of a variety of buildings and associated bituminous concrete and Portland cement concrete (PCC) pavement areas. The pavement areas, subjected to significant loading associated with heavy truck traffic and metal stockpiling, were beginning to fail.
Subgrade preparation
The project involved the re-construction and addition of PCC pavement. S.W.COLE performed subsurface explorations at the site (including test borings) and developed design plans for new PCC pavement. The client wanted to utilize reclaimed aggregate base materials from reclaimed bituminous pavements, and S.W.COLE performed blend analyses and made recommendations for optimum reclaim depths to generate an acceptable new product.
S.W.COLE was also retained during construction to provide geotechnical field personnel to observe soil subgrade preparation for pavement and structure areas. We sampled recycled and imported aggregate base materials for laboratory and field testing for gradation and compaction and provided field and laboratory testing of the concrete used to construct the PCC pavement.
