The proposed project will further develop the technology of “Full-Depth Cold In-Place Recycling (CPR) of Asphalt Pavements with Self Cementing Fly Ash” by establishing the engineering methodologies required for (1) the design of rehabilitated pavement, and (2) the construction monitoring of the recycled road base. The results of the proposed project will be targeted to the so-called low traffic volume flexible or built-up pavements. Counties and local governments have large networks of rural and county roads that are classified as low traffic volume pavements, best described as conglomerates of base course and wearing course of chip seal or other asphalt overlays that have been built up over many years. A demonstration of the CPR process on approximately 2.5 miles of such roadway was conducted in August 2004. The proposed project will build upon the results obtained in this demonstration project and will have the following two objectives: (1) establish the parameters for engineering design of rehabilitated road pavements with fly ash stabilized recycled asphalt base layer, and (2) establish the parameters for rapid construction monitoring using Dynamic Cone Penetrometer. The deliverable of the proposed project will be a comprehensive design and construction guide including model specification, preconstruction testing program, methods for engineering design of rehabilitated road pavements with fly ash stabilized recycled asphalt base layer, and procedures for construction quality control and quality assurance.
