Pavement performance is contingent on effective pavement design that addresses the subgrade soil properties, projected traffic loadings, construction materials, and climatic conditions. At FERN CEM CORP we have designed pavements for many types of projects including state roadways, municipal roadways, ports, airports, intermodal facilities, and parking lots. We are capable of producing pavement designs that …
With every organization looking to cut costs wherever possible, how do you know if a hiring a pavement consultant is worth the cost?

However subsequent performance and terms may cause questions/issues to arise. …

Urban fill material containing debris including ash and coal encountered during assessment activities require classification. For example, S-1 classification may be based upon the high frequency of use by adults and children and/or high intensity of activities at the Site. The MCP may provide exemptions from reporting and/or cleanup for specific conditions that are common …
As part of your pre-project investigation, you may elect to extract pavement cores (samples) of the existing pavement to understand the prevailing conditions (existing pavement thickness & soils type below paved surface). After some preconstruction investigation, on some projects we have discovered that the underlying surface is PCC. The stresses triggered by a PCC sublayer …
Whether a roadway or parking lot, the pavement and underlying material need to withstand the loading being applied, this is the “use” consideration. The stresses at the bottom layer of the pavement (subgrade) is part of the consideration when selecting the application. Understanding these quality characteristics will inform the scope of the project, so that …
